Abstract

Little is known about what happens when no action, except for the protected weight bearing advocated for all postoperative care, is taken. For this reason, we set forth to examine the biologic response to a gap in a well-established dog model using a non-weight bearing porous-coated CoCrMo implant. The authors have characterized in detail an animal model of a porous-coated implant with a gap between the implant and bone of a magnitude often seen in cementless arthroplasty under controlled conditions ( stable gap; no micromotion). This model lends itself to future use in the evaluation of various treatment modalities which may or may not enhance osteoneogenesis across a gap.
