Abstract
According to the invention, there is provided a trial implant and method of using same. The implant includes 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 opening appointed to expose a portion of the resected bone of the femur, including guide structure for guiding a tool along a predetermined path for controlled shaping of a patellar groove in the bone exposed through the opening. Removal of any portion of the bracket or guide structure is unnecessary following the shaping steps prior to performing a trial reduction.
