ABSTRACT:
The invention provides a modular system of components used as bone preparation tools and trial prosthesis components. The system includes a trial tibial tray bearing element that mounts upon a prepared tibia, a punch bushing that serves the purpose of a trial tibial stem and helps to guide a tibial punch through the tibia. The trial template element, the punch bushing and the tibial punch can remain in position on the patient's tibia while one or more trial tibial bearing inserts or samples are attached thereto to determine the proper fit and orientation of a prosthesis.
