[0005] On the other hand, patients having damaged posterior cruciate ligaments may be fitted with a "posterior stabilized" femoral component. A "posterior stabilized" femoral component includes a bone engaging surface and articulating surface similar to that of the "standard" femoral component. The "posterior stabilized" femoral component differs, in part, from the "standard" femoral component in that it includes a femoral box protruding outwardly from the distal portion of the bone engaging surface and extending along the edge of the intracondylar notch. Accordingly, when preparing the femur to receive a "posterior stabilized" femoral component, a femoral box cut must be made in the distal end of the femur to accommodate the femoral box.
