Patellofemoral resurfacing is a partial knee replacement involving the areas of both patella and femur where they come into contact.
The femoral component - also called a trochlear implant.
Patella to show cut line. The lower half is discarded.
Polyethylene button cemented onto undersurface of cut patella.
Materials for resurfacing
The femur component is usually metal, while the patellar component is usually ultrahigh molecular weight polyethylene. The polyethylene component for the patella has small 'feet' that are cemented into holes drilled into the undersurface of the cut bone.
