ABSTRACT:
A femoral knee prosthesis having a box internal geometry adjacent the femur which has four intersecting planes which extend from the medial side of the prosthesis to the lateral side. Shims of varying thickness can be added which retain the same internal box geometry. The internal geometry of the shims comprises three intersecting planes. Medial and lateral shims are provided. The internal geometry of the shims is translated slightly anteriorly as they increase in thickness. The shims may be added to either condyle independently, with different thickness on each side.
