FEMORAL TROCHLEA PROSTHESES

摘要

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.

主权项

1. A method of surgically repairing a distal femur of a knee joint comprising the steps of:
providing a femoral trochlea prosthesis comprising:
an articulating surface having a posterior-most end;a nonarticulating surface opposite the articulating surface; andat least one fixation support that projects from the nonarticulating surface, the posterior-most end of the articulating surface transitioning smoothly into the fixation support; positioning the nonarticulating surface of the prosthesis against the distal femur; and implanting the fixation support of the prosthesis into the distal femur so that the posterior-most end of the articulating surface of the prosthesis transitions smoothly into the distal femur.
