Abstract
An orthopedic jig or saw guide for preparing a femoral knee joint to receive the femoral component of a posterior stabilized prosthesis. The jig is adapted for cutting a central cavity in the distal end of the femur. In one embodiment, the cavity has a curved surface, the curve extending medial-laterally and a curved osteotome for incising a curved surface between the resulting two longitudinal incisions. The jig further comprises longitudinal saw guides for guiding a sagittal saw to make appropriate incisions parallel to the longitudinal axis of a femur.
