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

Joint replacements – what type of artificial implant does Mr Moss use?

Mr Moss uses a range of artificial implants, or prostheses, to replace diseased or damaged bone around joints. The implants mimic bone shape and can be made of metal, high density polyethylene or ceramic. They are made by Zimmer, the largest orthopaedic manufacturing company in the world.

Mr Moss is frequently used as a specialist advisor to Zimmer and works extremely closely with the prostheses manufacturer to develop some ground breaking products in the United Kingdom. Working this closely with Zimmer, Mr Moss has been able to successfully carry out some of the UK’s firsts for his patients.
