Patent ID: 7896922

Claim:
An apparatus to partially replace articulating surfaces of a knee joint, the apparatus comprising: a femoral implant including an outer bearing surface and an inner surface structured for attachment to the femur, said femoral implant comprising a single component that resurfaces the femoral trochlea and one femoral condyle, said single component structured to extend from the top of the patellofemoral groove and over one femoral condyle; and a tibial implant including an outer bearing surface structured to mimic and replace one plateau of a proximal tibia, said tibial implant positionable adjacent to said femoral implant; and a patellar implant including an outer bearing surface structured to mimic and replace a portion of the posterior surface of a patella, said patellar implant positionable adjacent to said femoral implant, wherein the outer bearing surface of said femoral implant is structured to contact said tibial implant and said patellar implant and further wherein the resulting configuration of the femoral implant and the tibial implant and the patellar implant articulate in a predetermined manner to restore proper kinematics.
