More Information
Summary:A bearing component of a medical implant is formed from an ultrahigh molecular weight polyethylene (UHMWPE) composite which comprises UHMWPE and a polyethylene copolymer having a polymer backbone and pendant hydrophilic groups or pendant surface active agents that are attached to the polymer backbone. The bearing material can exhibit reduced immune response and wear, and increased lubrication.
