Zusammenfassung:	PCT No. PCT/US91/05358 Sec. 371 Date Jan. 27, 1994 Sec. 102(e) Date Jan. 27, 1994 PCT Filed Jul. 29, 1991 PCT Pub. No. WO93/02641 PCT Pub. Date Feb. 18, 1993A prosthetic joint system is provided for use when replacement of bone is required. The system includes an elongated stem having a joint motion surface at one end and an outside surface which includes at least one tapered portion, a sleeve for fixation to the patient's bone which has an internal taper for locking engagement with the at least one tapered portion, and a bone replacement element which can be a bone graft. The system includes means for attaching the bone replacement element to the stem at a location between the joint motion surface and the sleeve. In the case of bone grafts, the system can include a second sleeve for implantation in the graft and a second tapered portion on the stem for locking engagement with the second sleeve. Preferably, a series of mating stems, sleeves, and bone replacement elements, or second sleeves in the case of bone grafts, are provided.
