Abstract
A thin plate patello-femoral-tibial resurfacing prosthesis is described. The patellar component is a metallic shell which is designed to be as thin as possible so as to retain maximum natural bone thickness and hence strength. The metallic patellar component articulates with a plastic insert in a metallic femoral component. The tibial bearing area of the femoral component is metallic for articulation with a plastic proximal tibial prosthesis.
