A bolt engages the washer and an elongate shaft portion of the bolt protrudes from the femoral component through the aperture in the washer and the aperture in the femoral component to engage a Morse taper post or femoral stem. The configuration of the washer aperture, its location in the washer, and the orientation of the washer within the femoral component determine the fore and aft positioning of the Morse taper post or femoral stem. The Morse taper post or femoral stem can be provided with a canted base to angle the post or stem with respect to the femoral component.Type: GrantFiled: August 14, 1996Date of Patent: October 20, 1998Assignee: Johnson & Johnson Professional, Inc.Inventors: Stefan M.
