Abstract

The invention is an improvement in a prosthetic device of the type that is a composite of a first material adapted to be strong enough to withstand the wear and stress exerted on the prosthetic device and a second material in the form of a coating fixed to the first material over a substantial portion of the outer surface of the prosthetic device that engages the bone to which the prosthetic device is attached. The coating is adapted to allow adjacent human tissue to grow therein. The improvement comprises the coating being at least 1 mm. thick and formed of a porous polymeric material that includes a network of interconnected pores throughout its volume. The average pore diameter of the coating ranges from 50 .mu.m - 300 .mu.m, the minimum pore volume being 30%.
