Abstract

Disclosed is a tool and an associated method for removing a prosthetic implant. Although the tool can be used to remove a variety of different prosthetic implants, it finds particular application in the removal of femoral implants. In one embodiment, both lateral and medial tools are utilized. The lateral tool includes a generally arcuate shape with upstanding sidewalls that define an arcuate interior. The lateral tool is thus dimensioned to follow the contour of the lateral side of a femoral implant. The medial tool includes opposing side walls that define an interior opening. The opening is sized to receive the neck of the femoral implant, thereby allowing the tool to closely follow the medial bone/implant interface.
