Joint Replacement Surgery

A Total Knee Replacement (TKR) or Total Knee Arthroplasty is a surgery that replaces an arthritic knee joint with artificial metal or plastic replacement parts called the ‘prostheses’.

The procedure is usually recommended for older patients who suffer from pain and loss of function from arthritis and have failed results from other conservative methods of therapy.

The typical knee replacement replaces the ends of the femur (thigh bone) and tibia (shin bone) with plastic inserted between them and usually the patella (knee cap).

Other causes include

    Trauma (fracture)
    Increased stress e.g., overuse, overweight, etc.
    Connective tissue disorders
    Obesity, as additional weight puts extra force through your joints which can
    lead to arthritis over a period of time
    Inflammation e.g., Rheumatoid arthritis

In an Arthritic Knee

    The cartilage lining is thinner than normal or completely absent. The degree of cartilage damage and inflammation varies with the type and stage of arthritis
    The capsule of the arthritic knee is swollen
    The joint space is narrowed and irregular in outline; this can be seen in an X-ray image
    Bone spurs or excessive bone can also build up around the edges of the joint

The combinations of these factors make the arthritic knee stiff and limit activities due to pain or fatigue.


The diagnosis of osteoarthritis is made on history, physical examination & X-rays.

There is no blood test to diagnose Osteoarthritis (wear & tear arthritis).
