摘要： A surgical instrument for shaping the distal femur of a patient to receive a unicondylar prosthetic component includes a cutting guide body that carries a pair of cylindrically shaped openings in the guide body, each of the openings having a central longitudinal axis and the respective axes of the openings forming an acute angle. An annular bushing is removably received in a selected one of the cylindrical openings during a cutting of the distal femur. A bone cutting reamer registers with a central cylindrical opening in the bushing. The bone cutting reamer has an annular shoulder that abuts the top of the bushing to define the depth of cut. During use, the surgeon positions the cutting guide body over a diseased condyle of the patient's distal femur. The surgeon then sequentially places the bushing and its associated bone cutting reamer into one of the selected openings of the cutting guide body. After placing the bone cutting reamer in the second opening of the guide body, the surgeon has formed two overlapping circular cuts which form an elongated oval shaped and three-dimensionally convex surface for receiving the unicondylar prosthesis.
