The AVON Patello-Femoral Joint Replacement is a useful alternative to TKR for patients with isolated patello-femoral arthritis. It has been conceived in such a manner that it can reproduce the natural patello-femoral joint throughout the range of motion. Additionally, it facilitates the patella in the femoral groove.
