Abstract: A femoral component for a prosthesis used in a total knee arthroplasty includes a posterolateral taper on the lateral condyle. The lateral and medial condyles of the femoral component are asymmetric to accommodate for the asymmetry of a resected lateral and medial condyle of a femur. The taper is designed to improve the fit of femoral component on the femur to eliminate or reduce overhang of the femoral component's lateral condyle, thereby reducing pain, irritation, stiffness, soreness, or any other symptoms of an improperly fitting prosthesis.
