Abstract: Various embodiments of femoral trochlea prostheses useable in a knee joint. The knee joint includes a patella and a distal femur with a femoral trochlea, or patello-femoral groove. In one embodiment, a femoral trochlea prosthesis includes a distal tail. In another embodiment, a femoral trochlea prosthesis includes a wing or extension portion. In yet another embodiment, a set of femoral trochlea prostheses includes a plurality of prostheses having differing thicknesses. In still another embodiment, a femoral trochlea prosthesis includes a porous medium on various portions of the prosthesis.
