SHAPING AND TRIAL REDUCTION GUIDE FOR IMPLANTATION OF FEMORAL PROSTHESIS AND METHOD OF USING SAME ABSTRACT According to the invention, there is provided a trial implant comprising a modular bracket defining a structure having an internal surface adapted to be seated on the distal aspect of a resected femur bone and an external surface with a shape resembling the normal distal condyle of the femur. The bracket has an elongated central opening appointed to expose the resected bone of the femur, including a pair of tracks for guiding a tool along a predetermined path for controlled shaping of a patellar groove in the bone exposed through the opening. A replacable insert covers the opening and articulates with a proximal aspect of the tibia during interoperative trial reduction of the knee joint, whereby prior removal of the bracket from the resected bone is unnecessary following shaping of the patellar groove. Preferably, the insert and guide tracks cooperate together to securely position the insert within the opening during trial reduction. A surgical method is also provided using the described trial implant guide.
