Abstract
A jig for resecting the distal end of a femur to receive a femoral component of a knee prosthesis. The jig has independent medial and lateral condyle sagittal saw guides. The guides aid a surgeon in cutting three of four resected surfaces or planes for each condyle. The femoral component accepts shims over either condyle to compensate for uneven loss of healthy bone. The shims do not change the internal geometry of the femoral component, but associate each proximal displacement with an anterior displacement of the geometry. Each saw guide slides on a slanted dovetail track so that the proper amount of anterior displacement can be maintained so that shims may maintain the common internal geometry.
