Introduction
    OA is one of the most common condition treated by
     the Physiotherapist.
    Osteoarthritis is the most common form of arthritis
     worldwide..
    It can occur in any synovial joint; the commonest
     sites being the knees, hips & small hand joints.
    Consequences of OA include pain, reduced function,
     & restriction in daily activities.
    Management is made complex because structural
     changes can occur without the patient displaying any
     symptoms.

       The word "arthritis," meaning "inflammation of a
        joint," is a misnomer.

       Carol David, 1999 Definition of OA vary, but
        considered to be a chronic degenerative &
        progressive condition affecting synovial joint.
       John Ebnezar, 2003 It is a degenerative, non-
        inflammatory joint disease characterized by
        destruction of articular cartilage & formation of
        new bone at the joint surface & margins.
       Royal College of Physician, 2008 OA refers to a
        clinical syndrome of joint pain accompanied by
        varying degrees of functional limitation & reduced
        quality of life.

       There is an underlying primary disease of the joint
        which leads to degeneration of the joint.
       It can occur at any age after adolescence.
       The predisposing factors are –
         Congenital  mal development of joint
         Irregularity of joint surface from previous trauma
         Previous disease producing a damage to articular
          cartilage
         Internal derangement of the knee
         Obesity & excessive weight

Pathology of oa
11


        OA is a multi-factorial, metabolically active
         process usually begins in middle age.
        It was thought to be only degenerative, but it have
         reparative features.
        The activity & behavior of chondrocytes provides
         the key to progressive nature of joint degeneration.

Patho-mechanics
12


        Increased in water content in articular cartilage
        Changes in quality of collagen fibers, which
         increased in diameter & disrupt collagen bundle.
        At molecular level – loss of proteoglycans in
         cartilage & severity of lesions appear to be
         proportional. (Lotts et al., 1987)
        Repeated weight bearing on such cartilage leads to
         fibrillation.
        Cartilage gets abraded by the grinding mechanism
                         P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Patho-mechanics cont…

        Further rubbing – subchondral bone become hard
         & glossy (eburnated)
        The bone at the margins of the joints hypertrophies
         to form a rim of projecting spurs known as
         osteophytes.
        The loose flakes of cartilage incite synovial
         inflammation & thickening of capsule.
        These leads to stiffness & deformities of the joint.

Incidence
14


        Affected 44% - 70% of population of age 55years.
        Symptomatic OA increased with age & weight
        Weight bearing joints are more affected.
        Relationship between osteoporosis & OA is largely
         increasing.
        Athletes involves in running does not reduce the
         incidence of OA.
        Age, genetic & presence of other local articular
         pathology affect the biomechanical structure of joint.

pain
18


        It is often most immediate importance to the patient
        Worsen at night – due to raised pressure in subchondral bone
         (Pinals, 1996)
        Often raised with movement & relive with rest.
        Many structure may give rise to pain in OA
            Periarticular soft tissue – capsular/ligament strain
            Periosteal elevation secondary to raised intraosseous pressure
            Muscular pain & weakness
            Inflamed & overstretched synovium
            Refer pain from spine
            Inability to cope

                               P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Muscle spasm
19


        It is a protective mechanism
        Movement cause pain so the body attempts to stop
         movement
        But prolong spasm cause pain due to metabolic
         accumulation & fatigue.
        Adaptive shortening may also occur in muscles.




                        P.R.Khuman MPT, Ortho & Sports   19-Jun-12
stiffness
20


        Probably deprivation of normal movement
        Subchondral micro-fractures heal & callus forms,
         this cause loss of joint mobility & stiffness




                        P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Inflammation & effusion
21


        It is not always present unless the joint is
         underwent over activity
        Sign & symptoms includes are –
          Heat

          Erythema

          Tenderness

          Effusion

          Discomfort   &
          Pain.

                            P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Loss of Range of motion
22


        Combination of joint pain, stiffness & possible
         effusion will often cause limitation of end ROM
        Certain joint may develop capsular pattern with
         restriction in certain ROM




                        P.R.Khuman MPT, Ortho & Sports   19-Jun-12
23



                            CAPSULAR PATTENS
Hip        Adduction contracture – due to increase force in lateral margin of acetabulum

Knee       Flexion contracture. 75% medial compartment, 25% lateral, 48% PF
Ankle      Increase valgus force – limited inversion & supination
Great toe Hallux valgus – restricted abduction
Shoulder   Adhesive capsulitis may develop – restricted abduction, lateral & medial rotation

Hands      The small joints of fingers are often involved.
DIP        Typically Heberden’s nodes – in 70% of OA hand
PIP        Bouchard’s nodes – in 35% of patients
MCP        In 10% of patients
CMC        In 60% of patients

                                 P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Muscle inhibition & atrophy
24


        Effusion will inhibit surrounding muscle of joint.
        This may be a safety mechanism as the intra
         articular pressure becomes relatively positive.
          E.g.quadriceps contraction may lead to rupture of
           knee joint capsule (Bland, 1994).
        Chronic muscle inhibition is often linked to chronic
         pain & will lead to atrophy & ensuring weakness.



                         P.R.Khuman MPT, Ortho & Sports   19-Jun-12
crepitus
25


        The flaked cartilage & eburnated bone end grate
         against each other characterized sound.
        Mild creaking – indicate synovitis
        Loud cracking – indicate advance disease




                        P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Joint instability
26


        Surrounding muscle weaken & imbalance
        Pain episodes are unpredictable causing joint to give
         away.
        These process together with chronic stretch of soft
         tissue will alter joint alignment.
        These will lead to instability & possibly subluxation




                        P.R.Khuman MPT, Ortho & Sports   19-Jun-12
deformities
27


        Osteophyte development reduce joint instability by
         increasing the peripheral articular surface area.
        Such deformities are more profound in established
         OA but may not developed equally on medial &
         lateral.
        This may contribute to varus & valgus deformities
        Together with the soft tissue laxity, it will alter
         normal joint biomechanics.

Radiographic finding
28


        X-ray changes –
          Loss of joint space
          Sclerosis

          Altered bone end shape

          Osteophytes

Reduce function
31


        All the clinical features described above can result
         in functional difficulty.
        Often described problems are – walking a distance,
         climbing stairs, getting out of chair, writing,
         opening jars etc.
        But most patients compensate by alternative ways
         of achieving the task.

ROLE OF KNEE LOADING IN Oa
33


        Knee loading plays a major role in OA knee
         development and progression.
        During the stance phase of gait, high loads are applied
         to knee in both sagittal and frontal planes.
        The most relevant load is the external knee adduction
         moment (AM) in the frontal plane generated because
         the ground reaction force vector (GRFv) passes medial
         to the joint center.
        This moment forces the knee laterally into varus & is
         resisted by an internal abduction moment, resulting in
         compression of the medial joint compartment &
         stretching of the lateral structures.

                          P.R.Khuman MPT, Ortho & Sports   19-Jun-12
ROLE OF KNEE LOADING IN Oa
34


        The AM influences the load distribution between
         the medial & lateral plateaus.
        The higher the AM the greater the load on the
         medial plateau relative to the lateral plateau.
        Importantly, the AM during gait is a factors known
         to predict OA progression in humans.
        A 20 to 30% increase in the AM is associated with a
         2.8 to 6.5 time increase in the risk of progression.

LOCAL MECHANICAL FACTORS Influencing KNEE
     LOADING & PHYSICAL THERAPY OUTCOMES
36


        The effectiveness of physical therapy interventions
         in knee OA is likely to differ depending on local
         mechanical factors.
        The main local mechanical factors are –
          Mal-alignment

          Laxity.




                           P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Mal-alignment
37


        The mechanical alignment of LL influences
         distribution of loads across the medial and lateral knee
         joint compartments.
        Pre-existing mal-alignment - contribute development
         of OA
        Or mal-alignment may arise - consequence of OA
         process due to cartilage loss, bony attrition, and
         meniscal damage.
        Mal-alignment has been shown to be mediator for the
         effects of other factors (such as obesity) on disease
         progression.
                          P.R.Khuman MPT, Ortho & Sports   19-Jun-12
38


        GRFv –
          In Neutrally Aligned Knee – passes slightly medial to
           knee joint
          In Varus Knee – displaced more medially to knee

          In Valgus Knee – passes more laterally to knee




                          P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Laxity
39


        Passive knee laxity refers to abnormal motion of
         tibia with respect to femur in unloaded state.
        It is determined by ligaments, joint capsule, other
         soft tissues, and the joint surfaces.
        Varus-valgus laxity has been found to be greater in
         people with knee OA.
        Dynamic stability relies on integrity of passive
         structures with the coordinated activity of muscles
         around the knee joint.
                        P.R.Khuman MPT, Ortho & Sports   19-Jun-12
40


        Declines in joint stability can lead to a change in
         load distribution.
        The cartilage may then be less able to withstand
         applied loads and this may lead to degeneration.

Diagnostic Approach to Joint
41
              Pain & OA
        Diagnosis of OA is made clinically based on –
          History

          Physicalexamination
          Laboratory and radiologic investigations
            To exclude inflammatory arthritis, secondary osteoarthritis,
             and non-articular causes of joint pain.

        A practical diagnostic approach to a patient
         presenting with joint pain, which is suspected to be
         due to osteoarthritis is to ask 3 questions:
         1.   Is the source of pain articular or non-articular?
         2.   If articular, is the pathology osteoarthritis?
         3.   If osteoarthritis, is the pathogenesis idiopathic
              (primary) or secondary?

     articular pain?
     Palpation is key in evaluation. Non-articular sources of joint pain include:
        Peri-articular soft tissue pain:                          Referred pain:, e.g. knee
            Ligament (tear/strain)                                 pain due to:
            Tendon (tendonitis, enthesitis)                        Hip pathology
            Muscle (myositis, myofascial pain, disuse              Myofascial piriformis pain
             atrophy, tight                                         Prolapsed lumbar disc with
            hamstrings)                                             sciatica.
            Fascia (fasciitis, iliotibial band syndrome)          Central pain:
            Bursa (bursitis)                                       Fibromyalgia
            Plica                                                  Restless Leg Syndrome

Is it osteoarthritis ?
44


        As osteoarthritis has no specific clinical
         characteristic or diagnostic laboratory test, and
         radiographic findings may not correlate with
         clinical severity, the diagnosis is made clinically
         based on history and physical examination, with
         laboratory and radiologic tests selectively
         undertaken to exclude inflammatory arthritis,
         secondary osteoarthritis, and non-articular causes
         of joint pain.

46


        Primary/idiopathic OA has a symmetrical predilection
         for joints of fingers, hips, knees & spine.
        Involvement of other joints should prompt an evaluation
         for secondary causes of osteoarthritis:
          Trauma, Charcot’s (neuropathic) joint, Avascular necrosis
          Inflammatory arthritis
              Crystal arthropathy
              Rheumatoid arthritis
              Septic arthritis

          A possible  role for quadriceps-strengthening ex in
           slowing disease progression was first explored in 1999.
          Muscle weakness (particularly quadriceps) is a well-
           recognized impairment in people with knee OA.
          It has been associated with increased pain & a greater
           deterioration in function over time.
          Quadriceps strengthening has formed the cornerstone
           of traditional OA exercise therapy.

          Quadriceps muscles play a large role in resisting the
           abduction moment (AM).
          Women with a moderate to high isokinetic quadriceps
           strength had respectively a 55% - 64% reduced risk of
           developing hip or knee OA.

          Control of varus-valgus laxity is largely produced by
           co-contraction of the quadriceps & hamstring muscles.
          An increase in hamstring strength was associated with
           less deterioration in function in people with knee OA.

Gait Retraining
66


        Gait patterns can influence loading at the knee joint,
         and thus changing them through gait retraining could
         slow disease progression.
        Parameters altering include – toe-out angle, walking
         speed & location of loading under foot during stance.
        Although patients may be able to alter their gait pattern
         when instructed in clinic, use of biofeedback devices,
         leg/foot taping, or other strategies may be necessary to
         allow the pattern to become habitual.

        Degree of toe-out
            It represents the angle of foot placement (FP)
            It is the measure of angle formed by each foot’s line of
             progression & a line intersecting the center of the heel
             and the 2nd toe.
            Normal angle for male 70
            The degree of toe-out decreases as the speed of walking
             increases in normal men.
        Toe-out angle –
            There was 10% reduction in odds of structural
             disease progression per additional 10 of toe-out angle.
            Thus, small alterations in toe-out angle may have
             clinically relevant effects.

        Walking speed –
          Itis another factor associated with knee load, with
           faster walking speeds increasing all knee loads
           (including the knee AM).
          Indeed, people with knee OA often walk more slowly
           than the average, which is thought to be an adaptive
           mechanism in reducing knee loads.

        Aerobic exercise – including cycling, swimming,
         and walking has been found to be effective for
         relieving symptoms in knee OA.
        Such exercise could also have benefits for longer-
         term joint health by assisting with weight
         reduction.
        the combination of dietary weight loss and exercise
         (including both aerobic and resistance components)
         was more effective in improving function and pain

          Realign unstable or structurally deficient joints with
           restoration of normal force distribution
          Improve proprioception; and improve stability and
           patient perception of instability.

          Wedged   insoles were first proposed as a treatment for
           knee OA in the 1980s by Japanese researchers.
          Wedged insoles exert a mechanical effect on the lower
           limb by altering the magnitude, temporal pattern, and
           plantar location of GRFv acting on the foot during gait.
          LW increase the subtalar joint valgus moment thereby
           reducing the moment arm of the knee AM arm in the
           frontal plane.

        Viscoelastic materials used in footwear or in insoles
         augment body tissues (particularly the heel pad) in
         reducing the magnitude of the heel-strike transient.
        With age, heel pad structure alters and results in a
         loss of shock absorbing capacity.
        Viscoelastic insoles can attenuate transient forces
         incurred during walking, running, stair climbing,
         and jumping activities.

        Electrotherapeutic modalities are widely used in PT
         departments to decrease pain associated with OA.
        Popular Rx include - US, IFT, SWD, LASER &
         TENS.
        The proposed physiological effects of these
         modalities include deep heating, increased blood
         flow, reduced muscle-spasm, promotion of
         inflammatory response, and pain relief.


                        P.R.Khuman MPT, Ortho & Sports   19-Jun-12
76


        There are many laboratory-based studies that
         demonstrate the physiological effects of electrotherapy
         modalities that should theoretically produce therapeutic
         effects.
        Until clinical trials replicate laboratory findings,
         electrotherapy cannot be considered an efficacious,
         cost-effective, evidence-based intervention for OA.
        However, it should be noted that patients generally like
         electrotherapy Rx & considerable placebo effects could
         be used to enhance other aspects of a Rx package.
                          P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Thermotherapy
77


        Heat applied through various heated packs, relieves
         pain
        Heat ‘close the pain gate’, improved local circulation,
         increased collagen extensibility, reduced muscle spasm,
         and improved ROM.
        Similarly, cold therapy applied through ice packs or
         baths may relieve pain via the ‘pain-gate’ mechanism,
         reduced peripheral nerve excitability, and reduction in
         joint effusions and oedema.
        Thermotherapy appears to be a simple, cost-effective,
         means of assisting pain control & therefore is an
         appropriate tool in patient self-management regimes.

78   P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Ultrasound (US)
79


        Ultrasound (US) is probably the most commonly
         used electrotherapy modality, especially for hip,
         knee, and vertebral OA.
        It is claimed to alters cell function, vascularity, and
         collagen extensibility, resulting in a
         proinflammatory effect.
        A meta-analysis of US in musculoskeletal
         conditions concluded that it has no role in the relief
         of pain.

                         P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Transcutaneous electrical
80
     nerve stimulation (TENS)
        TENS receives widespread use in many acute &
         chronic pain conditions.
        The main theoretical rationale for pain relief is that
         electrical stimulation of large diameter neural fibres
         ‘closes the pain gate’.
        Alternatively, counter-irritant stimulation may
         facilitate release of endogenous opioid substances.
        TENS can effect pain relief when used at high
         frequency or strong burst mode for more than four
         weeks.
                         P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Interferential therapy (IFT)
81


        Physiological effects of this modality differ according to
         level of stimulation & type of nerves fibres stimulated.
        Stimulation of motor nerves – Leads to muscle
         contraction, as a result increases circulation in the area.
        This is of limited use in OA where active exercise is of
         proven benefit
        Sensory nerve stimulation – Facilitating opioid
         production and ‘closing the pain-gate’.
        However, there is no evidence for its benefit in
         stimulating healing & only limited evidence supporting
         analgesic effects.
                          P.R.Khuman MPT, Ortho & Sports   19-Jun-12
SWD
82


        SWD have been used in a variety of orthopaedic
         and musculoskeletal conditions with varied
         success.
        Pulsed or continuous delivery results in tissue
         heating and subsequent increased circulation of
         treated area.
        Cell membrane potentials may also be effected
         although this theory remains contentious.
        Study suggested that pulsed Rx relieved pain in
         subjects with knee OA.
                        P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Low-level laser therapy (LLLT)
83


        LLLT has evolved as a therapeutic intervention for
         OA over the last decade.
        Therapeutic doses are too low to induce thermal
         effects within the tissues and the physiological
         benefits are thought to derive from photochemical
         reactions at cellular level, which produce an anti-
         inflammatory effect.
        A recent review failed to conclude whether LLLT
         was beneficial in Rx of OA.

                        P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Balneotherapy (hydrotherapy
     or spa therapy)
84


        Balneotherapy is one of the oldest recorded
         treatments for rheumatic conditions.
        It utilizes buoyancy—the assistant and resistant
         properties offered by water- in combination with
         the ‘healing’ effects of warm, mineral rich waters.
        The aim is to relieve muscle spasm, increase joint
         ROM and muscle strength, with subsequent
         improvement in function.


                         P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Spa Therapy
85


        Spa Therapy is normally delivered on a 2–3 week
         residential basis at spa resorts.
        It consists of daily thermal bathing, exercise
         sessions, mudpacks, and jet massage.




                       P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Hydrotherapy
86


        Hydrotherapy consisting of heated pool is popular with
         patients, and effective in relieving pain, improving
         joint ROM & patient function & quality of life.
        Due to demand and limited resources, Rx are normally
         of short duration with little possibility of follow-up Rx.
        Patients with a variety of rheumatic conditions benefit
         from balneotherapy, with reductions in pain and muscle
         spasm, and accompanying improvements in functional
         activities.
        At present it is an expensive intervention based on
         scientific evidence.
                          P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Walking aids
87


        Sticks & crutches are supplied to reduce the stress
         applied to weight bearing joints and to improve
         patient stability during ambulation.
        Unfortunately, walking aids are not always popular
         with patients, who perceive them as being for the
         elderly and infirm.
        They can also be impractical when performing
         other functional activities.


                        P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Walking aids cont…
88


        Historically, patients have been encouraged to use
         walking aids on the contralateral side to the
         problematic joint, thus encouraging improved
         weight distribution, and an energy efficient gait
         pattern.
        For knee patients walking aids function as a
         vertical load-sharing implement and cannot effect
         forces in the frontal plane.


                        P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Manual therapy
89


        Physiotherapists, osteopaths and chiropractors use
         manual techniques, to reduce joint pain and
         stiffness, and increase ROM.
        Manual therapy applied to knee together with an ex
         programme may be used to improve knee function
         & pain relief for patients with OA of the knee.
        Manipulation often gain short-term benefit.
        Studies suggest minimal efficacy in relieving pain,
         improving ROM and function.
                        P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Joint mobilization cont…
90


        Despite, it is still commonly used in outpatient
         departments in conjunction with other modalities
         such as electrotherapy and exercise.
        Further work is necessary to determine the efficacy
         of these interventions especially at different stages
         of disease progression, as there is a possibility that
         benefits will differ accordingly.



                         P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Massage
91


        Patients frequently report that rubbing or massaging a
         joint temporarily relieves pain, probably because the
         mechanical stimulus excites large diameter nerve fibres
         closing the pain gate.
        The additional application of topical agents may
         enhance the benefits of massage.
        However, one back pain study reported that massage
         was no better than manipulation, but was inferior to
         TENS, in relieving pain.
        Massage is likely to be used by patients and
         encouraged by practitioners.
                         P.R.Khuman MPT, Ortho & Sports   19-Jun-12
Patellar taping
92


        Aim is to control patellar tracking and minimize
         contact stress
        Most common method is medially directed taping
         to offload lateral compartment of PFJ
        Significant improvements in pain and physical
         function
        Direct effect on pain not attributable to placebo or
         cutaneous stimulation
        No research on long-term effects of taping or role
         in disease pathogenesis
                         P.R.Khuman MPT, Ortho & Sports   19-Jun-12

     recommendations for health
        Activity: Daily activity (walking, yard work, etc.)
        Frequency: Most days of the week
        Intensity: Moderate; 55–70% of age-predicted
         maximal heart rate; RPE 2–4
        Duration: Accumulate at least 30 minutes of
         activity (e.g., three 10-minute bouts)

Recommendations for physical
     fitness (muscular fitness)
95


        Mode: Dynamic, resistance exercise for major
         muscle groups
        Frequency: 2–3 days/week on alternate days
        Volume:
          8–10  exercises; resistance adequate to induce
           moderate, volitional fatigue after 8–12 repetitions.
          If the subject is more than 50–60 years of age or frail,
           or the primary goal is to improve endurance, choose a
           level of resistance that will produce moderate fatigue
           after 10–15 repetitions.

Osteoarthritis

  • 1. OSTEOARTHRITIS OR O = Old age, A = Arthritis By: Dr. P. Ratan Khuman (PT) M.P.T., (Ortho & Sports) Sr. Lecturer C.U. Shah Physiotherapy College
  • 2. Introduction  OA is one of the most common condition treated by the Physiotherapist.  Osteoarthritis is the most common form of arthritis worldwide..  It can occur in any synovial joint; the commonest sites being the knees, hips & small hand joints.  Consequences of OA include pain, reduced function, & restriction in daily activities.  Management is made complex because structural changes can occur without the patient displaying any symptoms. 19-Jun-12 P.R.Khuman MPT, Ortho & Sports 2
  • 3. introduction cont… 3  The word "arthritis," meaning "inflammation of a joint," is a misnomer. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 4. Definition 4  Carol David, 1999 Definition of OA vary, but considered to be a chronic degenerative & progressive condition affecting synovial joint.  John Ebnezar, 2003 It is a degenerative, non- inflammatory joint disease characterized by destruction of articular cartilage & formation of new bone at the joint surface & margins.  Royal College of Physician, 2008 OA refers to a clinical syndrome of joint pain accompanied by varying degrees of functional limitation & reduced quality of life. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 5. classification 5  According to number of joint involved –  Mono articular  Oligo or Poly articular  According to type of OA described –  Inflammatory  Erosive OA  Generalized OA (GOA)  Other classifications –  Primary idiopathic OA  Secondary OA  Endemic OA Cooper, 1994 P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 6. Primary (idiopathic) oa 6 1. Localized - hands and feet, knee, hip, spine or other joint 2. Generalized - three or more joint areas  It occurs in old age, mainly in weight bearing joints (Hip, knee)  It is more common than secondary OA. M. Sofue, N. Endo, 2007 P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 7. Secondary oa 7  There is an underlying primary disease of the joint which leads to degeneration of the joint.  It can occur at any age after adolescence.  The predisposing factors are –  Congenital mal development of joint  Irregularity of joint surface from previous trauma  Previous disease producing a damage to articular cartilage  Internal derangement of the knee  Obesity & excessive weight P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 8. Examples of secondary oa 8  Developmental  Trauma (acute or chronic)  Congenital hip dislocation  Accidental  Legg-Calves-Perthes disease  Sports injury  Congenital hip dislocation  Occupational  Epiphyseal dysplasias  Iatrogenic (post-surgical)  Mechanical  Metabolic  Hypermobility syndromes  Hemachromatosis  Leg length discrepancy  Mucopolysaccharidoses  Mal-alignment  Gout  Pseudogout  Calcium crystal deposition P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 9. 9  Endocrine  Miscellaneous  Acromegaly  Hemophilias  Hyperparathyroidism  Paget’s disease  Hypothyroidism  Osteonecrosis  Inflammatory  Neuropathic  Any systemic arthropathy rheumatic disease  Septic arthritis P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 10. Endemic oa 10  Only found in a certain population or in a certain region (M. Sofue, N. Endo, 2007) P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 11. Pathology of oa 11  OA is a multi-factorial, metabolically active process usually begins in middle age.  It was thought to be only degenerative, but it have reparative features.  The activity & behavior of chondrocytes provides the key to progressive nature of joint degeneration. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 12. Patho-mechanics 12  Increased in water content in articular cartilage  Changes in quality of collagen fibers, which increased in diameter & disrupt collagen bundle.  At molecular level – loss of proteoglycans in cartilage & severity of lesions appear to be proportional. (Lotts et al., 1987)  Repeated weight bearing on such cartilage leads to fibrillation.  Cartilage gets abraded by the grinding mechanism P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 13. Patho-mechanics cont… 13  Further rubbing – subchondral bone become hard & glossy (eburnated)  The bone at the margins of the joints hypertrophies to form a rim of projecting spurs known as osteophytes.  The loose flakes of cartilage incite synovial inflammation & thickening of capsule.  These leads to stiffness & deformities of the joint. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 14. Incidence 14  Affected 44% - 70% of population of age 55years.  Symptomatic OA increased with age & weight  Weight bearing joints are more affected.  Relationship between osteoporosis & OA is largely increasing.  Athletes involves in running does not reduce the incidence of OA.  Age, genetic & presence of other local articular pathology affect the biomechanical structure of joint. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 15. How common is arthritis? 15  1 in 8 people have osteoporosis.  1 in 10 people have osteoarthritis.  1 in 33 people have fibromyalgia.  1 in 100 people have rheumatoid arthritis.  1 in 1,000 children have juvenile chronic arthritis.  1 in 1,000 people have ankylosing spondylitis.  1 in 2,000 people have systemic lupus erythematosus.  1 in 10,000 people have scleroderma. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 16. Tissue involved in OA Cartilage Focal softening and loss Bone Osteophyte, sclerosis, but subchondral osteopenia Capsule Thickening Synovium Thickening and modest inflammation Muscle Atrophy and weakness Ligaments Degeneration Bursae Secondary bursitis Angiogenesis (formation of new blood vessels), Vessels avascular necrosis, venous hypertension 16 P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 17. Clinical features 17  Pain  Muscle spasm  Stiffness  Inflammation  Loss of ROM  Capsular pattern  Muscular inhibition & atrophy  Joint instability  Crepitus  Deformities  Reduce function P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 18. pain 18  It is often most immediate importance to the patient  Worsen at night – due to raised pressure in subchondral bone (Pinals, 1996)  Often raised with movement & relive with rest.  Many structure may give rise to pain in OA  Periarticular soft tissue – capsular/ligament strain  Periosteal elevation secondary to raised intraosseous pressure  Muscular pain & weakness  Inflamed & overstretched synovium  Refer pain from spine  Inability to cope P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 19. Muscle spasm 19  It is a protective mechanism  Movement cause pain so the body attempts to stop movement  But prolong spasm cause pain due to metabolic accumulation & fatigue.  Adaptive shortening may also occur in muscles. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 20. stiffness 20  Probably deprivation of normal movement  Subchondral micro-fractures heal & callus forms, this cause loss of joint mobility & stiffness P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 21. Inflammation & effusion 21  It is not always present unless the joint is underwent over activity  Sign & symptoms includes are –  Heat  Erythema  Tenderness  Effusion  Discomfort &  Pain. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 22. Loss of Range of motion 22  Combination of joint pain, stiffness & possible effusion will often cause limitation of end ROM  Certain joint may develop capsular pattern with restriction in certain ROM P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 23. 23 CAPSULAR PATTENS Hip Adduction contracture – due to increase force in lateral margin of acetabulum Knee Flexion contracture. 75% medial compartment, 25% lateral, 48% PF Ankle Increase valgus force – limited inversion & supination Great toe Hallux valgus – restricted abduction Shoulder Adhesive capsulitis may develop – restricted abduction, lateral & medial rotation Hands The small joints of fingers are often involved. DIP Typically Heberden’s nodes – in 70% of OA hand PIP Bouchard’s nodes – in 35% of patients MCP In 10% of patients CMC In 60% of patients P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 24. Muscle inhibition & atrophy 24  Effusion will inhibit surrounding muscle of joint.  This may be a safety mechanism as the intra articular pressure becomes relatively positive.  E.g.quadriceps contraction may lead to rupture of knee joint capsule (Bland, 1994).  Chronic muscle inhibition is often linked to chronic pain & will lead to atrophy & ensuring weakness. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 25. crepitus 25  The flaked cartilage & eburnated bone end grate against each other characterized sound.  Mild creaking – indicate synovitis  Loud cracking – indicate advance disease P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 26. Joint instability 26  Surrounding muscle weaken & imbalance  Pain episodes are unpredictable causing joint to give away.  These process together with chronic stretch of soft tissue will alter joint alignment.  These will lead to instability & possibly subluxation P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 27. deformities 27  Osteophyte development reduce joint instability by increasing the peripheral articular surface area.  Such deformities are more profound in established OA but may not developed equally on medial & lateral.  This may contribute to varus & valgus deformities  Together with the soft tissue laxity, it will alter normal joint biomechanics. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 28. Radiographic finding 28  X-ray changes –  Loss of joint space  Sclerosis  Altered bone end shape  Osteophytes P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 29. Kellgren & Lawrence grading system for osteoarthritis Grade 0 Normal Grade 1 Doubtful narrowing of joint space, possible osteophyte Grade 2 Definite osteophyte, possible narrowing Moderate multiple osteophytes, definite narrowing, some Grade 3 sclerosis, possible deformity of bone ends Large osteophytes, marked narrowing, severe sclerosis, Grade 4 definite deformity of bone ends 29 P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 30. 30 P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 31. Reduce function 31  All the clinical features described above can result in functional difficulty.  Often described problems are – walking a distance, climbing stairs, getting out of chair, writing, opening jars etc.  But most patients compensate by alternative ways of achieving the task. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 32. Inter-relationship of symptoms & sign in OA Inflammation Effusion Pain Loss of ROM Muscle Instability Muscle atrophy Inhibition Reduce Function 32 P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 33. ROLE OF KNEE LOADING IN Oa 33  Knee loading plays a major role in OA knee development and progression.  During the stance phase of gait, high loads are applied to knee in both sagittal and frontal planes.  The most relevant load is the external knee adduction moment (AM) in the frontal plane generated because the ground reaction force vector (GRFv) passes medial to the joint center.  This moment forces the knee laterally into varus & is resisted by an internal abduction moment, resulting in compression of the medial joint compartment & stretching of the lateral structures. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 34. ROLE OF KNEE LOADING IN Oa 34  The AM influences the load distribution between the medial & lateral plateaus.  The higher the AM the greater the load on the medial plateau relative to the lateral plateau.  Importantly, the AM during gait is a factors known to predict OA progression in humans.  A 20 to 30% increase in the AM is associated with a 2.8 to 6.5 time increase in the risk of progression. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 35. 35 P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 36. LOCAL MECHANICAL FACTORS Influencing KNEE LOADING & PHYSICAL THERAPY OUTCOMES 36  The effectiveness of physical therapy interventions in knee OA is likely to differ depending on local mechanical factors.  The main local mechanical factors are –  Mal-alignment  Laxity. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 37. Mal-alignment 37  The mechanical alignment of LL influences distribution of loads across the medial and lateral knee joint compartments.  Pre-existing mal-alignment - contribute development of OA  Or mal-alignment may arise - consequence of OA process due to cartilage loss, bony attrition, and meniscal damage.  Mal-alignment has been shown to be mediator for the effects of other factors (such as obesity) on disease progression. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 38. 38  GRFv –  In Neutrally Aligned Knee – passes slightly medial to knee joint  In Varus Knee – displaced more medially to knee  In Valgus Knee – passes more laterally to knee P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 39. Laxity 39  Passive knee laxity refers to abnormal motion of tibia with respect to femur in unloaded state.  It is determined by ligaments, joint capsule, other soft tissues, and the joint surfaces.  Varus-valgus laxity has been found to be greater in people with knee OA.  Dynamic stability relies on integrity of passive structures with the coordinated activity of muscles around the knee joint. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 40. 40  Declines in joint stability can lead to a change in load distribution.  The cartilage may then be less able to withstand applied loads and this may lead to degeneration. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 41. Diagnostic Approach to Joint 41 Pain & OA  Diagnosis of OA is made clinically based on –  History  Physicalexamination  Laboratory and radiologic investigations  To exclude inflammatory arthritis, secondary osteoarthritis, and non-articular causes of joint pain. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 42. 42  A practical diagnostic approach to a patient presenting with joint pain, which is suspected to be due to osteoarthritis is to ask 3 questions: 1. Is the source of pain articular or non-articular? 2. If articular, is the pathology osteoarthritis? 3. If osteoarthritis, is the pathogenesis idiopathic (primary) or secondary? P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 43. Is it articular or non- 43 articular pain? Palpation is key in evaluation. Non-articular sources of joint pain include:  Peri-articular soft tissue pain:  Referred pain:, e.g. knee  Ligament (tear/strain) pain due to:  Tendon (tendonitis, enthesitis)  Hip pathology  Muscle (myositis, myofascial pain, disuse  Myofascial piriformis pain atrophy, tight  Prolapsed lumbar disc with  hamstrings) sciatica.  Fascia (fasciitis, iliotibial band syndrome)  Central pain:  Bursa (bursitis)  Fibromyalgia  Plica  Restless Leg Syndrome  Fat pad (Hoffa’s syndrome)  Complex regional pain  Blood vessel (aneurysm, varicose veins) syndrome (Sudeck’s  Bone (avascular necrosis, tumour) dystrophy).  Nerve (neuroma). P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 44. Is it osteoarthritis ? 44  As osteoarthritis has no specific clinical characteristic or diagnostic laboratory test, and radiographic findings may not correlate with clinical severity, the diagnosis is made clinically based on history and physical examination, with laboratory and radiologic tests selectively undertaken to exclude inflammatory arthritis, secondary osteoarthritis, and non-articular causes of joint pain. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 45. “red-flags” to alert diagnosis of oa 45 P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 46. Is it primary or secondary oa? 46  Primary/idiopathic OA has a symmetrical predilection for joints of fingers, hips, knees & spine.  Involvement of other joints should prompt an evaluation for secondary causes of osteoarthritis:  Trauma, Charcot’s (neuropathic) joint, Avascular necrosis  Inflammatory arthritis  Crystal arthropathy  Rheumatoid arthritis  Septic arthritis  Congenital/developmental P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 47. pattern of joint involvement 47  Primary OA can be further subdivided into localized or generalized (involving 3 or more sets of joints)  The more common joints involved in OA are shown shaded in the figure: P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 48. 48 Management of Oa  Pharmacological  Conservative  Surgical P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 49. Pharmacologic Rx of OA 49  Acetaminophen  NSAIDs  Non-selectiveNSAID  COX-2 selective  Tramadol, opioids  Joint injection  Supplements  Glucosamine  Chondroitin sulfate etc. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 50. 50 PHYSICAL THERAPY INTERVENTIONS FOR KNEE OA ―Those who think they have not time for bodily exercise will sooner or later have to find time for illness‖ —Edward Stanley, British Prime Minister (1799-1869) P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 51. Aims of physical therapy 51  To educate the patient  To reduce pain, inflammation & stiffness  To eliminate aggravating factors  To maintain or improvement of ROM  To maintain or improvement, of muscle strength  To restore muscle balance  To reduce stress on the involved joints  To retrain gait  To maintain or improvement in functional independence, including participation in a vocational activities P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 52. Patient Education 52  A major objective of education is to improve patient knowledge in order to integrate him or her into the decision-making team.  Content should include information concerning OA pathophysiology, clinical presentations, how the disease is assessed, its natural course & the indications and expected results of various Rx modalities.  The route of administration include discussions with health professionals, group discussion or self-reviewed materials (e.g., booklets, web sites). P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 53. Exercise 53  Goal of exercise –  To prevent or delay disability.  An exercise program should incorporate –  To lessen pain during activity  To increase or maintain joint ROM,  To strength muscle,  To stabilize joint &  To improve aerobic capacity or level of conditioning.  Exercise in OA should be adapted according to the presence and severity of pain. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 54. exercise cont… 54  In painful episodes –  Isometric exercise  Non weight-bearing exercise (OCK)  e.g., biking, rowing with adapted tools or  Partial weight-bearing exercises (CKC)  e.g., aquatic exercises should be recommended.  In painless (or less painful) periods –  The exercise program may include progressive muscle performance exercises. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 55. Strengthening Specific Muscles 55  Quadriceps Muscle Strengthening –  A possible role for quadriceps-strengthening ex in slowing disease progression was first explored in 1999.  Muscle weakness (particularly quadriceps) is a well- recognized impairment in people with knee OA.  It has been associated with increased pain & a greater deterioration in function over time.  Quadriceps strengthening has formed the cornerstone of traditional OA exercise therapy. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 56. Strengthening Specific 56 Muscles cont…  Quadriceps Muscle Strengthening – cont…  Quadriceps strengthening ex have consistently found significant reductions in pain & improvements in physical function.  Stronger quadriceps muscles reduced the risk of developing radiographic knee OA.  Quadriceps muscles play a large role in resisting the abduction moment (AM).  Women with a moderate to high isokinetic quadriceps strength had respectively a 55% - 64% reduced risk of developing hip or knee OA. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 57. Strengthening Specific 57 muscles cont…  Hamstring Muscle Strengthening –  Weakness of the hamstring muscles has been found in patients with knee OA.  Control of varus-valgus laxity is largely produced by co-contraction of the quadriceps & hamstring muscles.  An increase in hamstring strength was associated with less deterioration in function in people with knee OA. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 58. Strengthening Specific 58 muscles cont…  Hip Abductor Strengthening (Frontal plane mover)–  Strengthening the hip abd muscles controlling pelvic position in frontal plane may reduce knee loads and slow disease progression.  Weakness of hip abductor –  Drop in the level of the pelvis,  Shifting the center of mass (COM) and  Increasing the knee AM.  Strengthening abductor muscles could reduce knee load by increasing toe-out during gait P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 59. Strengthening Specific 59 muscles cont…  Hip adductor muscles (Frontal plane mover) –  Assist in resisting the knee AM – particularly in a varus mal-aligned knee.  Eccentrically restrain the tendency of the femur to move into further varus  Knee OA had stronger hip adductors compared with age-matched controls group.  Hip strengthening could be a novel intervention for rehabilitation of knee OA patients. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 60. Fig: Hip adductor muscles reduce knee varus by their distal attachment to the proximal femur. 60 P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 61. Strengthening Specific 61 muscles cont…  Strengthening of hip extensor (Sagittal plane mover) –  Hip extensor muscle play an important role in dynamically stabilizing hip & pelvic in sagittal plane.  The gluteus maximus act as a restraint for forward progression during gait.  It also helps to minimize deformity in sagittal plane.  E.g. hip & knee flexion deformity  Strengthening should consider both short & long lever P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 62. Exercise – stretching 62  Stretching ex for hip flexor, hamstring & calf musculature helps improving ROM, pain & flexibility of knee OA.  It should be made as a routine part of Rx. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 63. Recommendations for 63 musculoskeletal flexibility  Mode: Gentle static stretching  Frequency: Minimum 2–3 days/week  Intensity: Stretch to a position of mild tension/discomfort  Duration: Hold position for 10–30 seconds  Repetitions: 3–4 repetitions for each stretch P.R.Khuman MPT, Ortho & Sports 19-Jun-12

Gait Retraining 66  Gait patterns can influence loading at the knee joint, and thus changing them through gait retraining could slow disease progression.  Parameters altering include – toe-out angle, walking speed & location of loading under foot during stance.  Although patients may be able to alter their gait pattern when instructed in clinic, use of biofeedback devices, leg/foot taping, or other strategies may be necessary to allow the pattern to become habitual. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 67. Gait retraining cont… 67  Degree of toe-out  It represents the angle of foot placement (FP)  It is the measure of angle formed by each foot’s line of progression & a line intersecting the center of the heel and the 2nd toe.  Normal angle for male 70  The degree of toe-out decreases as the speed of walking increases in normal men.  Toe-out angle –  There was 10% reduction in odds of structural disease progression per additional 10 of toe-out angle.  Thus, small alterations in toe-out angle may have clinically relevant effects. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 68. Gait Retraining cont… 68  Walking speed –  Itis another factor associated with knee load, with faster walking speeds increasing all knee loads (including the knee AM).  Indeed, people with knee OA often walk more slowly than the average, which is thought to be an adaptive mechanism in reducing knee loads. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 69. Aerobic Exercise 69  Aerobic exercise – including cycling, swimming, and walking has been found to be effective for relieving symptoms in knee OA.  Such exercise could also have benefits for longer- term joint health by assisting with weight reduction.  the combination of dietary weight loss and exercise (including both aerobic and resistance components) was more effective in improving function and pain in people with knee OA P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 70. Orthoses/ knee bracing 70  Supports, braces & corrective devices may assist in relieving pain & improving function of affected joints.  They are used –  To reduce vertical forces applied to skeleton at heel strike  Realign unstable or structurally deficient joints with restoration of normal force distribution  Improve proprioception; and improve stability and patient perception of instability.

  • 72. FOOTWEAR AND INSOLES 72  Lateral Wedges (LW) –  Wedged insoles were first proposed as a treatment for knee OA in the 1980s by Japanese researchers.  Wedged insoles exert a mechanical effect on the lower limb by altering the magnitude, temporal pattern, and plantar location of GRFv acting on the foot during gait.  LW increase the subtalar joint valgus moment thereby reducing the moment arm of the knee AM arm in the frontal plane.

  • 74. Shock-absorbing Insoles 74  Viscoelastic materials used in footwear or in insoles augment body tissues (particularly the heel pad) in reducing the magnitude of the heel-strike transient.  With age, heel pad structure alters and results in a loss of shock absorbing capacity.  Viscoelastic insoles can attenuate transient forces incurred during walking, running, stair climbing, and jumping activities. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 75. Electrotherapy for pain 75  Electrotherapeutic modalities are widely used in PT departments to decrease pain associated with OA.  Popular Rx include - US, IFT, SWD, LASER & TENS.  The proposed physiological effects of these modalities include deep heating, increased blood flow, reduced muscle-spasm, promotion of inflammatory response, and pain relief. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 76. 76  There are many laboratory-based studies that demonstrate the physiological effects of electrotherapy modalities that should theoretically produce therapeutic effects.  Until clinical trials replicate laboratory findings, electrotherapy cannot be considered an efficacious, cost-effective, evidence-based intervention for OA.  However, it should be noted that patients generally like electrotherapy Rx & considerable placebo effects could be used to enhance other aspects of a Rx package. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 77. Thermotherapy 77  Heat applied through various heated packs, relieves pain  Heat ‘close the pain gate’, improved local circulation, increased collagen extensibility, reduced muscle spasm, and improved ROM.  Similarly, cold therapy applied through ice packs or baths may relieve pain via the ‘pain-gate’ mechanism, reduced peripheral nerve excitability, and reduction in joint effusions and oedema.  Thermotherapy appears to be a simple, cost-effective, means of assisting pain control & therefore is an appropriate tool in patient self-management regimes.

  • 79. Ultrasound (US) 79  Ultrasound (US) is probably the most commonly used electrotherapy modality, especially for hip, knee, and vertebral OA.  It is claimed to alters cell function, vascularity, and collagen extensibility, resulting in a proinflammatory effect.  A meta-analysis of US in musculoskeletal conditions concluded that it has no role in the relief of pain. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 80. Transcutaneous electrical 80 nerve stimulation (TENS)  TENS receives widespread use in many acute & chronic pain conditions.  The main theoretical rationale for pain relief is that electrical stimulation of large diameter neural fibres ‘closes the pain gate’.  Alternatively, counter-irritant stimulation may facilitate release of endogenous opioid substances.  TENS can effect pain relief when used at high frequency or strong burst mode for more than four weeks. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 81. Interferential therapy (IFT) 81  Physiological effects of this modality differ according to level of stimulation & type of nerves fibres stimulated.  Stimulation of motor nerves – Leads to muscle contraction, as a result increases circulation in the area.  This is of limited use in OA where active exercise is of proven benefit  Sensory nerve stimulation – Facilitating opioid production and ‘closing the pain-gate’.  However, there is no evidence for its benefit in stimulating healing & only limited evidence supporting analgesic effects. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 82. SWD 82  SWD have been used in a variety of orthopaedic and musculoskeletal conditions with varied success.  Pulsed or continuous delivery results in tissue heating and subsequent increased circulation of treated area.  Cell membrane potentials may also be effected although this theory remains contentious.  Study suggested that pulsed Rx relieved pain in subjects with knee OA. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 83. Low-level laser therapy (LLLT) 83  LLLT has evolved as a therapeutic intervention for OA over the last decade.  Therapeutic doses are too low to induce thermal effects within the tissues and the physiological benefits are thought to derive from photochemical reactions at cellular level, which produce an anti- inflammatory effect.  A recent review failed to conclude whether LLLT was beneficial in Rx of OA. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 84. Balneotherapy (hydrotherapy or spa therapy) 84  Balneotherapy is one of the oldest recorded treatments for rheumatic conditions.  It utilizes buoyancy—the assistant and resistant properties offered by water- in combination with the ‘healing’ effects of warm, mineral rich waters.  The aim is to relieve muscle spasm, increase joint ROM and muscle strength, with subsequent improvement in function. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 85. Spa Therapy 85  Spa Therapy is normally delivered on a 2–3 week residential basis at spa resorts.  It consists of daily thermal bathing, exercise sessions, mudpacks, and jet massage. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 86. Hydrotherapy 86  Hydrotherapy consisting of heated pool is popular with patients, and effective in relieving pain, improving joint ROM & patient function & quality of life.  Due to demand and limited resources, Rx are normally of short duration with little possibility of follow-up Rx.  Patients with a variety of rheumatic conditions benefit from balneotherapy, with reductions in pain and muscle spasm, and accompanying improvements in functional activities.  At present it is an expensive intervention based on scientific evidence. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 87. Walking aids 87  Sticks & crutches are supplied to reduce the stress applied to weight bearing joints and to improve patient stability during ambulation.  Unfortunately, walking aids are not always popular with patients, who perceive them as being for the elderly and infirm.  They can also be impractical when performing other functional activities. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 88. Walking aids cont… 88  Historically, patients have been encouraged to use walking aids on the contralateral side to the problematic joint, thus encouraging improved weight distribution, and an energy efficient gait pattern.  For knee patients walking aids function as a vertical load-sharing implement and cannot effect forces in the frontal plane. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 89. Manual therapy 89  Physiotherapists, osteopaths and chiropractors use manual techniques, to reduce joint pain and stiffness, and increase ROM.  Manual therapy applied to knee together with an ex programme may be used to improve knee function & pain relief for patients with OA of the knee.  Manipulation often gain short-term benefit.  Studies suggest minimal efficacy in relieving pain, improving ROM and function. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 90. Joint mobilization cont… 90  Despite, it is still commonly used in outpatient departments in conjunction with other modalities such as electrotherapy and exercise.  Further work is necessary to determine the efficacy of these interventions especially at different stages of disease progression, as there is a possibility that benefits will differ accordingly. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 91. Massage 91  Patients frequently report that rubbing or massaging a joint temporarily relieves pain, probably because the mechanical stimulus excites large diameter nerve fibres closing the pain gate.  The additional application of topical agents may enhance the benefits of massage.  However, one back pain study reported that massage was no better than manipulation, but was inferior to TENS, in relieving pain.  Massage is likely to be used by patients and encouraged by practitioners. P.R.Khuman MPT, Ortho & Sports 19-Jun-12
  • 92. Patellar taping 92  Aim is to control patellar tracking and minimize contact stress  Most common method is medially directed taping to offload lateral compartment of PFJ  Significant improvements in pain and physical function  Direct effect on pain not attributable to placebo or cutaneous stimulation  No research on long-term effects of taping or role in disease pathogenesis P.R.Khuman MPT, Ortho & Sports 19-Jun-12
