Abstract
A load-bearing plastic orthopaedic joint implant, formed aat least partially of UHMWPE or HDPE material, and a process of subjecting at least the load-bearing surface thereof to ion implantation so as to improve its surface characteristics are disclosed. Such improved surface characteristics result, inter alia, from the formation in the treated surfaces, of increased carbon to carbon bonds, diamond-like carbon chain scissions and wherein the implanted ions do not form precipitate chemical compounds with the plastic material.
