Patent ID: 8888858

Claim:
A method of surgically repairing a distal femur of a knee joint comprising the steps of: providing or obtaining a femoral trochlea prosthesis comprising: an anterior articulating surface; an anterior non-articulating surface opposite the anterior articulating surface; a distal articulating surface having a posterior-most end; a distal non-articulating surface opposite the distal articulating surface and oriented at an angle relative to the anterior non-articulating surface; and a fixation support that extends from a base coupled to the distal non-articulating surface to a tip opposite the base, the fixation support oriented at an angle relative to the distal non-articulating surface; resecting an anterior surface of the distal femur; positioning the distal non-articulating surface of the prosthesis against a patella-femoral joint of the distal femur; and implanting the tip of the fixation support of the prosthesis into a distal end of the distal femur so that the tip of the fixation support of the prosthesis is surrounded by bone of the distal femur, wherein the implanting step comprises positioning the fixation support of the prosthesis at an acute angle relative to the resected anterior surface of the distal femur.
