Knee Pain

The knee is a hinge joint formed between the tibia and femur (tibio-femoral). The patella glides over the front of femoral condyles to form a patellofemoral joint. The stability of the knee depends primarily upon its ligaments.


Osteoarthritis Knee

Osteoarthritis (OA) is a degenerative joint disease. Aetiology is multifactorial, and still not understood. Commonly it is thought to be wear and tear of joints as one ages. It occurs in elderly people, mostly in the major joints of the lower limb, frequently bilaterally.

Types: Two types of Osteoarthritis are recognized – Primary & Secondary.

Predisposing Factors are:


Osteoarthritis is a degenerative condition primarily affecting the articular cartilage. The first change observed is an increase in water content and depletion of the proteoglycans from the cartilage matrix. Repeated weight bearing on such a cartilage leads to its fbrillation. The cartilage gets abraded by the grinding mechanism at work at the points of contact between the apposing articular surfaces, until eventually the underlying bone is exposed. With further ‘rubbing’, the subchondral bone becomes hard and glossy. Meanwhile,the bone at the margins of the joint hypertrophies to form a rim of projecting spurs known as osteophytes. The loose flakes of cartilage incite synovial inflammation and thickening of the capsule, leading to deformity and stiffness of the joint.
