摘要：
A medical prosthesis for use within a body which is formed of radiation treated ultra high molecular weight polyethylene having substantially no detectable free radial. Preferred prosthesis exhibits reduced production of particles from the prosthesis during wear of the prosthesis, and are substantially oxidation resistant. Methods of manufacturing wear resistant medical prosthesis and materials used therein are also provided.
