Knee injuries are very common, especially in athletes and workers. The knee is a complex joint made of bones, ligaments, tendons and cartilage that allow flexion and extension. Common work-related knee injuries include strains, ligament tears, cartilage injuries, tendon injuries and fractures. Injuries to the ACL, meniscus and articular cartilage are most frequent. Treatment depends on the injury but may include RICE, rehabilitation, bracing, surgery and activity modification. Surgical reconstruction is often needed for severe ligament and tendon injuries.
Ankle and Foot Injuries for Athletes - Dr. Andre Ross - Livingston Library, 9...Summit Health
This document discusses common foot and ankle injuries in athletes. It notes that foot and ankle injuries account for around 25% of sports injuries and cost an average of $21,000-$24,000 per claim. The most common acute injuries are sprains, fractures, tendon ruptures, and toe fractures/dislocations. The most common overuse injuries are plantar fasciopathy, tendinopathy, stress fractures, and joint instability. Treatment options for various injuries like ankle sprains, Achilles tendon injuries, and plantar fasciopathy are also outlined. The document emphasizes the importance of early treatment to prevent long-term disability.
Clavicle fractures are common injuries, especially in young active individuals participating in sports. The majority occur in the midshaft of the bone from direct blows or falls. Nonoperative treatment is usually sufficient but displaced fractures may require surgery. Physical exam and x-rays can diagnose and classify the fracture. Most heal with rest, but operatively fixing displaced fractures can improve outcomes.
Traumatic knee dislocations are rare injuries that require careful evaluation and management. According to the document, knee dislocations often result from high-energy injuries like motor vehicle collisions or falls. A thorough examination is needed to assess vascular and neurological status. Imaging can identify associated fractures. While some stable injuries may be treated non-operatively, unstable injuries or those with ligament disruption typically require surgical reconstruction. Complications may include neurovascular injuries, infections, and long-term issues like osteoarthritis. Early surgical intervention within 3 weeks of injury may lead to better outcomes compared to delayed treatment.
This document provides an overview of lower extremity fractures, focusing on pelvic fractures, fractures of the neck of the femur, and intertrochanteric fractures of the femur. Key points include the relevant anatomy, mechanisms of injury, clinical evaluation, classification systems, treatment approaches, and potential complications for each type of fracture. Radiographic evaluation and the importance of assessing hemodynamic status and associated injuries are also discussed.
This document summarizes information about soft tissue injuries of the knee joint, focusing on injuries to the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL).

The document reviews musculoskeletal injuries, including causes, classifications, clinical manifestations, assessment approaches, diagnosis, and management of common injuries such as fractures, dislocations, sprains and strains. It provides details on anatomy of the musculoskeletal system and discusses evaluation and treatment of various musculoskeletal traumas including splinting techniques.
This document provides information on traumatology and various injuries to the upper and lower limbs, head, chest, and spine. It begins with learning outcomes and definitions of traumatology. It then discusses fractures and injuries to specific areas like the shoulder girdle, scapula, humerus, radius, forearm, carpal bones, and metacarpals. For each injury, it covers topics like causes, signs and symptoms, treatment options, and potential complications. The goal is to help manage various acute physical injuries requiring immediate medical attention.
Distal femur fractures are traumatic injuries involving the region extending from the distal metaphyseal-diaphyseal junction to the articular surface of the femoral condyles.
Diagnosis is made radiographically with CT studies often required to assess for intra-articular extension.
Treatment is generally operative with ORIF, intramedullary nail, or distal femur replacement depending on available bone stock, age of patient, and patient activity demands.
Patella Fractures are traumatic knee injuries caused by direct trauma or rapid contracture of the quadriceps with a flexed knee that can lead to loss of the extensor mechanism.
Diagnosis can be made clinically with the inability to perform a straight leg raise and confirmed with radiographs of the knee.
Treatment is either immobilization or surgical fixation depending on fracture displacement and integrity of the extensor mechanism.
Proximal third tibia fractures are relatively common fractures of the proximal tibial shaft that are associated with high rates of soft tissue compromise and malunion (valgus and procurvatum).
Diagnosis is made with orthogonal radiographs of the tibia with CT scan often required to assess for intra-articular extension.
Treatment generally consists of surgical open reduction and internal fixation (ORIF) versus intramedullary nail fixation.

Pelvic ring injuries can be complex with implications for stability and associated injuries. Classification systems evaluate fracture pattern, stability, and mechanism of injury to guide management. Imaging with radiographs, CT, and MRI is important for evaluation. Initial management focuses on resuscitation, stabilization with pelvic binder or external fixation, and treatment of associated injuries. Definitive treatment depends on fracture pattern and stability, and may include closed reduction, skeletal traction, internal fixation with plates or screws, or angiographic embolization for bleeding. Long term implications can include urinary, sexual, or obstetrical complications. Close coordination between orthopedic and other specialties is important for optimal care.

- Injuries to the anterior cruciate ligament (ACL) are common in sports requiring pivoting movements and can range from mild sprains to complete tears.
- Mechanisms of ACL injury often involve sudden deceleration, landing from a jump with the knee in valgus, or lateral cutting maneuvers without contact.
- Diagnosis involves clinical exam including Lachman's and anterior drawer tests along with imaging like MRI to visualize ligament integrity.
- Treatment options include rehabilitation for mild injuries or reconstruction surgery followed by lengthy physical therapy focusing on regaining range of motion and strength.
1) The document discusses common knee injuries in athletes, including injuries to the ACL, PCL, MCL, and LCL ligaments as well as meniscal tears.
2) It describes the anatomy of the knee including the bones, ligaments, tendons, and cartilage. The four major ligaments - ACL, PCL, MCL, and LCL - are identified.
3) The causes, signs and symptoms, and treatment options for ligament injuries and meniscal tears are outlined. Twisting injuries are a common cause and treatments may include RICE, rehabilitation, bracing, and activity modification.
Pelvic fractures can be classified based on their stability and the mechanism of injury. Unstable and partially stable fractures often require surgical fixation while stable fractures may be treated non-operatively. Initial management focuses on controlling hemorrhage through fluid resuscitation, pelvic binding, angiography, or preperitoneal packing. Definitive treatment is then aimed at anatomic reduction and stabilization of the pelvis through external or internal fixation depending on the fracture pattern and stability. Close monitoring for complications such as infection, neurological injury, or persistent instability is important.
This document provides information about knee dislocations, including:
- It defines knee dislocation as displacement of the tibia in relation to the femur and discusses the rare incidence and demographics.
- Mechanisms of injury can be high-energy from accidents or low-energy from athletics, with hyperextension often causing anterior dislocations and dashboard injuries often causing posterior dislocations.
- Associated injuries include vascular, nerve, and fractures in 60% of cases.
- Classification systems include the Kennedy system based on tibial displacement direction and the Schenck system based on ruptured ligaments.
- Presentation includes symptoms of pain, swelling and instability or obvious deformity, with 50% sometimes
The document summarizes thoracolumbar spine injuries, including:
- Anatomy of the thoracic and lumbar spine regions which predispose the thoracolumbar junction to injury.
- Epidemiology showing these injuries most commonly affect segments T11-L2 and have bimodal age distribution.
- Classification systems including Denis, McCormack, and TLICS which evaluate morphology, neurology, and ligamentous integrity to determine treatment.
- Treatment principles aim to preserve neurology, minimize compression, stabilize the spine, and rehabilitate the patient either via non-operative or operative means.
The document discusses knee dislocations, including classifications, clinical assessment, management, and complications. It provides details on examining patients, investigating injuries, treating acute injuries with reduction and stabilization, and managing with surgery or conservatively. Surgical reconstruction is generally preferred over repair and aims to restore joint stability and kinematics through techniques like staged or single procedures and various graft options.
Knee injuries in sports medicine & arthroscopydocortho Patel
knee ligaments injuries are so incresing in sports persons & even in accidental trauma.here providing you basic knowledge of these injuries & arthroscopy treatment
This document defines different types of sports injuries and provides injury data for several sports. It describes acute injuries as having rapid onset from trauma, while chronic injuries develop over time from repetitive stress. Overuse injuries can result from intrinsic athlete factors or extrinsic training factors. Epidemiological studies examine injury risk factors and rates. For many sports like football, basketball, wrestling and soccer, the most common injuries are strains, sprains and contusions to the lower extremities. Injury rates often vary by age, sex and position.
Clavicle fractures are common injuries, especially in young active individuals. The majority occur in the midshaft region due to its thin bone and lack of muscle protection. Treatment depends on the location and degree of displacement/shortening. Nondisplaced fractures are usually treated nonsurgically with slings or strapping. Displaced fractures may require plate fixation, intramedullary nails, or coracoclavicular ligament repair/reconstruction to achieve union and restore function. Complications can include nonunion, malunion, hardware irritation, and neurovascular injury.
Osteoarthritis is the most common form of arthritis that affects the joints, especially in those over 45 years old. It involves the breakdown of cartilage in the joints which leads to pain, stiffness, and reduced mobility. Risk factors include age, genetics, joint injuries, and obesity. Symptoms may include joint pain, stiffness, swelling, and grinding sensations. Diagnosis involves physical exams, x-rays showing cartilage loss and bone spurs, and ruling out other causes. Treatment focuses on reducing pain and inflammation with medications and physical therapy, as well as weight loss and joint protection. For severe cases, surgical options like joint replacement may be considered.
Tibial plafond fractures are fractures of the distal tibial articular surface that account for less than 10% of lower extremity injuries. They most commonly occur in patients aged 35-40 due to high-energy trauma like motor vehicle accidents or falls from heights. These fractures are characterized by articular impaction, metaphyseal comminution, and soft tissue injury. Treatment involves immobilization for stable fractures without displacement, but displaced or intra-articular fractures often require surgical treatment like open reduction internal fixation or external fixation to reduce fragments and allow for monitoring of soft tissues. Complications can include wound problems, infection, malunion, arthritis, and stiffness.

Thoraco-lumbar fractures are common injuries that occur primarily from motor vehicle accidents. Several classification systems exist to characterize the injuries including the commonly used Denis classification, Load Sharing classification, and AO classification system. The Thoracolumbar Injury Classification and Severity Score (TLICS) system incorporates injury morphology, neurological status, and posterior ligamentous complex integrity to determine a score to guide treatment decisions. A score of 4 or less generally indicates non-surgical management while a score of 5 or more indicates surgery is needed. The timing of surgery remains unclear but early decompression may improve outcomes in neurologically compromised patients. Treatment is based on fracture stability, deformity, and neurological status.

The document summarizes the anatomy, classification, treatment and complications of clavicle fractures and acromioclavicular (AC) joint injuries. Key points:
- Clavicle fractures are classified using the Allman or Neer system, with most (80%) occurring in the middle third.
- Treatment depends on fracture type and displacement, with non-displaced fractures typically treated non-operatively and displaced/unstable fractures often requiring surgery.
- AC joint injuries use the Rockwood classification, with Types I-III usually treated non-operatively and Types IV-VI requiring surgery.
- Surgical options include plate fixation, CC screw fixation, hook plates or ligament reconstruction,
This document summarizes the presentation on clavicle fractures by Dr. K Maneesh Chandra. It discusses the mechanisms of injury, physical exam findings, imaging modalities, anatomy, treatment options and management of complications for clavicle fractures in infants, children and adults. Surgical treatment involves open reduction and internal fixation with plates or screws while non-surgical treatment uses sling immobilization. Complications are addressed and factors influencing treatment choice are outlined.

utilize arthroscopy to identify, study and treat
knee injuries in athletes in a minimally invasive
manner to maximize functional outcomes and
minimize morbidity
11
13. Epidemiology
Knee injuries in the adult general population:
• 4/1000 community adults
• 46% women (older); Likely non-sports
related
• 54% men (younger); Likely sports related
13
14. Epidemiology
Knee injuries in the adult general population:
• 37% knee injuries required orthopedic surgeon’s
care
• 12% required surgical care
14
15. Classification of Knee Injuries:
Ligament injuries to the knee are the more common than any
other type of major knee pathology
15
16. Classification of Ligament Injuries:
ACL injuries are the most common ligament injured in the
knee.
> 200,000 ACL ruptures occur in the U.S. annually **
16
17. Epidemiology
• The knee is the most commonly injured joint by adolescent
athletes with an estimated 2.5 million sports-related
injuries presenting to EDs annually.
• The most common diagnoses:
• strains and sprains (42.1%)
• contusions and abrasions (27.1%)
• lacerations and punctures (10.5%).

24. Definitions
• Strain- muscle or tendon is overstretched or torn.
• Sprain- a stretching or tearing of a ligament
• Contusion- a region of injured tissue or skin in which blood capillaries have
been ruptured; a bruise
• Laceration- a deep cut or tear in skin or flesh
• Acute- injuries less than 3 months old

• Ligament- structure that attaches a bone to a bone
• Tendon- structure that attaches a muscle to a bone
24
25. Mechanism of Injury
Closely evaluating the mechanism of a reported
injury can often times delineate between industrial
and non-industrial disorders identified in the knee.

28. Mechanism of
Injury
Causation
C4 Form
• Not a holy grail
• Often filled out while patient
under duress
• Patient not educated on
medical terminology
• Filled out by other party
present with patient
28
29. Mechanism of
Injury
Causation
Patient history: critical to
identifying mech of injury
and determining causation
Witnesses/Video: when
available often play an
important role when an injury
is disputed
29
32. Orthopedic Surgical Emergencies
Involving the Knee
These injuries require immediate surgical
intervention often within a finite time frame (ie; 4-6
hours after the injury) to prevent limb/life
threatening complications or sequelae
32
33. Orthopedic Surgical Emergencies
Involving the Knee
• Knee dislocation (tibio-femoral)
• Open knee joint (Penetrating trauma or
laceration into the joint itself)

Surgical Treatment
Different patients require different methods of ACL
reconstruction (patient’s knee = patient’s
choice……w/guidance)
Various surgical techniques, methods of fixation, and
tissue/graft selection are within the standards of care
Surgeon must be ready, willing and able to utilize a
number of methods, tissues or fixation devices to
obtain best possible outcome
44

Patellar tendon deficiency
Irritation, partial or complete tear or loss of
function of the Quadricep or Patellar tendon
66
67. Quadricep/Patellar Tendon
Deficiency
Mechanism of Injury
The injury involves an awkward landing from a
jumping position where the quadriceps muscle is
contracting, but the knee is being forcefully
straightened. This is a so-called eccentric
contraction.
Eccentric load: An eccentric contraction is the motion of
an active muscle while it is lengthening under load.
67
74. Meniscal Tears
Medial / Lateral meniscus
Tear of the meniscal cartilage in the medial or
lateral compartment of the knee
74
75. Meniscal Tears

91. Articular (Hyaline) Cartilage
Deficiency
Chondromalacia
Abnormal softening or degeneration of the cartilage in a joint,
especially the knee.
Chondromalacia is often seen as an overuse injury in sports and
work. In other cases, improper knee & muscle alignment is the
cause.
A progressive, degenerative process in older patients.
It is not felt to be a precursor to DJD when it occurs in the young.
91
93. Chondromalacia
Common etiology
• Trauma, especially a fracture (break) or dislocation of the kneecap
• An imbalance of the muscles around the knee (Some muscles are
weaker than others.)
• Overuse (repeated bending or twisting) of the knee joint, especially
during sports
• Poorly aligned muscles or bones near the knee joint
• Injury to a meniscus (C-shaped cartilage inside the knee joint)
• Rheumatoid arthritis or osteoarthritis
• An infection in the knee joint
• Repeated episodes of bleeding inside the knee joint
• Repeated injections of steroid drugs into the knee
Harvard Health Publication
93
94. Chondromalacia
Symptoms
• Dull ache/pain in front half of knee
• Effusion
• Grinding sensation
• Mechanical symptoms
• popping, catching, locking
• Instability
94
98. • Patella: accounts for 1% of all fractures, most common in
ages 20-50
• Femoral condyles: these usually fracture when the knee
is stressed.
• Tibial plateau: compressive fractures of the articular
surface, typically from extreme force such as fall from a
height or being hit by a vehicle, although in patients with
osteoporosis minimal force may be needed.
98
100. Knee dislocation
This is a relatively rare injury resulting from dislocation between the femur
and tibia. It is a highly traumatic event which may be associated with
serious vascular injury. It often presents with multisystem trauma, and it is a
high-energy traumatic injury usually associated with road traffic accidents
and severe falls. It results in marked soft tissue damage.
A surgical emergency!!
Patellar dislocation
This is common, especially in young active individuals. Most dislocations
are lateral, and are accompanied by pain and swelling. Damage to the
medial ligaments is common. Dislocation may occur when the foot is
planted on the ground and a rapid change of direction or twisting occurs.
Usually pre-existing ligamentous laxity is present, and when patellar
dislocation has occurred once, it may recur owing to the consequent
ligament damage. Relocation to the patellar groove is often spontaneous as
the leg is straightened.[
100
102. Treatment of a W/C Knee Injury
Primary Goals
• Treat an injured worker in the most
appropriate, cost effective, efficient manner
• Return a patient to their pre-injury level of
activity as soon as possible (maximize
functional outcomes)
• Minimize impairment (limit morbidity)
102
103. Treatment of a W/C Knee Injury
Maximal Medical Improvement (MMI)
When a condition is well stabilized and unlikely to change
substantially in the next year with or with out medical
treatment.
May or may not be a permanent impairment associated with
the injury
103
104. Treatment of a W/C Knee Injury
Treatment “Guidelines”
ODG
ACOM
Presley Reed Disability Guidelines
104
105. Treatment of a W/C Knee Injury
W/C guidelines are NOT Standard of Care or
based on Evidenced Based Medicine for the
treatment of specific orthopedic injuries.
105
106. Impairment Ratings
Different ways of measuring impairment
Anatomic loss - damage to an organ or body structure
Functional loss - change in the function of the organ or
body structure (range of motion, strength, stability)
Diagnosis Based Estimate - impairment based on
diagnosis rather than on physical findings
106
111. Example Rating
• 25 y.o male underwent an uncomplicated ACL
reconstruction ~12 weeks ago.
• ~12 weeks (33-36 visits) of P.T. to date. His R.O.M. is
progressing albeit slowly
• Current R.O.M.; -7 to 105 degrees
current rating
4%WP (-7 ext) + 4%WP (105 flexion) = 8% WP
PPD Award = $25,935
111
112. Example Rating
2 additional weeks PT (6 visits x $100/visit)
2 additional weeks of modified work ($480 x 2)
Additional cost of 2 weeks care
($480 x 2) + ($100 x 6) = $1560
Functional Target knee: (-4 ext, 110 flexion)
Pt’s range of motion improves to -4 to 112 degrees
112
113. Example Rating
loss of function no longer applies to this patient’s
rating. Reverts back to a diagnosis based estimate,
which is typically 3% WP rating.
PPD award = ~ $9,725
113
114. Example Rating
Total Savings
$25,935 (original PPD award) - $9,725 (PPD
award after 6 additional PT) - $1,560 (additional
costs of treatment = $14,650 savings
114
115. Functional Targets
Physicians responsible for the care of W/C
patients must know, understand and strive for
the functional targets of the knee.
Being able to communicate with a “peer”
during “peer reviews” when discussing a
patient’s care that is falling outside of the W/C
“guidelines” is critical.
115
116. Conclusion
The knee is an amazing structure, but it must
observe the laws of physics (biomechanics)
to maintain it’s integrity….. just like a bridge
or skyscraper.
When abnormal or excessive forces (loads)
overcome a specific structure within the
knee a traumatic injury (failure) occurs.
116
117. Conclusion
A basic understanding of the actual
mechanisms of injury (forces) that can (cannot)
cause a specific structure in the knee to fail can
help determine if a specific accident/event
caused a medically identified injury,
(causation).
117
118. Conclusion
Ultimately, the goal in treatment of an injured
knee structure is to restore functional stability,
strength and motion to that knee.
This maximizes functional outcome for the
patient, minimizes their impairment.
118
119. Conclusion
Allowing treatment to continue @ times longer
than the suggested “guidelines” may benefit
the patient, insurance company and employer
by achieving functional targets, hence
increasing the functional outcome of a patient
and decreasing the impairment/ impairment
rating/PPD award.
119
120. Conclusion
Each knee injury requires a multi-faceted
approach when striving to return patient to a
pre-injury level or to maximize their functional
outcome.
Physician, patient and 3rd party payer must
partner and communicate with each other to
achieve a functional outcome.
120
121. Conclusion
For the most appropriate, efficient and cost effective
treatment of an injured worker, treating physicians and
decision makers must familiarize themselves with functional
targets when making critical treatment decisions.
Rigidity when working with the “guidelines” is not in the
best interest of any party or individual involved.
