Partial Knee Replacement (Patello Femoral)

This operation involves replacing some of the knee cap and
the area which the knee cap moves. The area in which the knee cap (patella)
moves is known as the patella groove, it is this area where a normal knee has a
layer of cartilage.  If this cartilage
has worn out it can be painful and can be replaced with a metal surface. A
plastic (polyethylene) disc is put on the back of the knee cap and articulates
with the new metal surface. This type of operation has been conducted for over
15 years but in small numbers (around 600 per year across the UK)
