摘要: Disclosed is a bearing material of medical implant comprising polymer such as UHMWPE and surface active agent that not covalently bonded to the polymer. The includes hydrophilic moiety or segment, an ethoxylated moiety, hydrophobic alkanol, alkenol, aromatic alcohol, alkylamine, alkenyl amine, alkyl alkanoic acid, alkenoic any combination thereof. has reduced wear rate. Also disclosed method reducing rate polymeric when it articulates against hard counterface in presence synovial fluid, providing fluid close proximity surface, counterface, both.
