2. Introduction
• OA (degenerative joint disease) is
characterized by progressive destruction
of hyaline cartilage followed by remodeling
of affected joint.
• The term osteoarthrosis is preferred as
primary pathological process is more
degenerative than inflammatory.

3. • OA is separated in to primary and
secondary forms.
• Primary- when there is no obvious
underlying cause.
• Secondary – when there is an identifiable
etiological factor such as inflammatory
arthropathy (R.A), infection, fracture with
disruption of articulating surfaces, LLD etc
• Families with early onset OA due to rare,
inherited mutations of collagen have been
described.

4. Epidemiology
• OA is the most common form of arthritis.
• Its prevalence steadily increases with age,
radiological changes of OA are seen in the
knee of more than 50 % of the population
older than the age of 60 yrs.
• At of after 75 yrs virtually every one has
evidence of OA in at least one joint.
• Men and women are equally affected
before age of 45, but after age 45 the
prevalence is higher in women.

12. • Surgical procedures
o Debridement
o Synovectomy
o Bursectomy
o Joint replacement
o Osteotomy
o Arthrodesis
o For wrist and hand – procedures using
silastic posthesis.

13. PT management
• Osteoarthritis
o Electrotherapy- SWD, cryo, therapeutic US,
TENS
o Ultrasound - controversial use
o Coldtherapy- to be applied for 15 to 20 min.

14. o TENS-Applied for a period of 30 to 45 min,
leads to approximately three hours of pain
relief, improves sleep, and reduces intake
of pain relieving med.
o Mobilization- to improve joint mobility and
decrease pain by using selected grading,
gentle distraction and stretching the
capsule tissue can be useful to increase
mobility.

15. o Exercise- dynamic preferred over
isometric.
o Walking- at least 3 times a week for 30
minutes, provided lower extremity will
tolerate walking or same can be done in a
swimming pool.
o Knee bracing- the use of knee bracing for
pain relief.
o Assistive devices- canes and crutches.
o Taping
