Not infrequently, especially in women, the area of the knee between the underside of the patella (kneecap) and the front of the femur (thigh bone) wears out. The patient particularly notices a crunching sensation within the joint and problems on inclines or stairs as well as getting up out of chairs.

If this happens in isolation then the front surface of the femur (trochlea) is resurfaced with a metal prosthesis and a polythylene or plastic implant resurfaces the underside of the patella. The attraction here of course is that if only the patella or kneecap is worn, the patient may keep the rest of the natural knee without operation whilst a much reduced procedure is performed to resurface the patellofemoral joint.

This procedure is much smaller than a total knee replacement and patients achieve a faster recovery.

If wear and tear subsequently occurs in the main part of the knee joint, it is possible to resurface that area around the patellofemoral replacement without resorting to a total knee joint replacement.

Frequently Asked Questions

What tests will confirm the diagnosis of osteoarthritis?

Osteoarthritis is often visible on X-rays. Cartilage loss is indicated if the normal space between the bones is narrowed, if there is an abnormal increase in bone density, or if bony projections or erosions are evident. A blood test is often taken to rule out rheumatoid arthritis.

Mr Moss will conduct an examination of your joint and will ask you to describe the pain. He will record your medical history, often asking you a series of questions about injuries, infections, ailments you have experienced, and any medications you are taking.

From this information and examination, Mr Moss will choose the most appropriate treatment option for you.
