Patello-femoral replacement

In a minority of patients their arthritis is confined to the patello-femoral joint (between the knee cap and the lower end of the thigh bone). Providing the rest of the knee is in good condition these patients can be treated by patello-femoral replacement (see picture). The advantage of this procedure is that only the diseased part of the knee is replaced and the main weight bearing parts of the knee are preserved. If, in the future, the arthritis should progress then the procedure can easily be converted to a total knee replacement.
