Abstract
A set of instruments ( ) is provided for use in the preparation of a natural bone of a condylar joint for receiving prosthetic components both in primary and revision surgery. To illustrate the invention and use thereof, reference is made to the preparation of a natural femur (F) in a knee joint. The set of instruments ( ) includes an anterior-posterior femoral resection guide ( ) having a guide aperture ( ) formed therethrough, and a set of collets ( A; B) formed to detachably mount to the guide aperture ( ). The set of collets ( A; B) includes a drill guide ( ), a reamer sleeve ( ), and a plurality of different size reamer bushings ( A; B). Accordingly, the drill guide ( ) can be mounted to the anterior-posterior femoral resection guide ( ) to provide guidance in the drilling of a channel ( ) into the distal end of a femur (F), and, alternatively, the combination of the reamer sleeve ( ) and the reamer bushings ( A; B) can be used to provide guidance in reaming a channel into the distal end of a femur (F). As an additional feature, a tibial template ( ) is also provided which can be cooperatively used with the reamer sleeve ( ) and reamer bushings ( A; B) to prepare a channel into a natural tibia (T).
