Abstract
This invention relates generally to the art of orthopaedic prostheses, and more particularly to the type of prosthesis which is adapted to promote the ingrowth of bone and/or tissue into the portion of the prosthesis surface in contact with the bone surface. The prosthesis is comprised of a bottom base layer of porous fiber metal material an intermediate metal reinforcing layer including at least one opening therein and a top non-metal surface which is molded to the base layer. The portion of the polyethylene layer that is in contact with the base layer penetrates into the interstices of the porous metal material, hence securing the non-metal layer to the porous metal base layer.
