Abstract
A multi-piece knee resection instrument for use in forming an anterior cut, an anterior chamfer cut, a posterior cut and a posterior chamfer cut on a distal femur which has already had a distal surface thereof resected which cuts are for the mounting of a prosthetic implant, has a first resection guide for attachment to the medial or lateral side of the distal femur. The first resection guide has a first surface facing generally anteriorly when mounted and a second surface extending distally from the first surface and angled thereto and a third surface extending generally parallel to the resected distal surface of the femur. A second resection guide is mounted on the first and second surfaces of the first resection guide for performing the anterior and anterior chamfer cuts. A third resection guide is mounted on the third surface of the first resection guide and extends in a medial-lateral direction therefrom across at least part of the resected distal femoral surface.
