摘要
A bearing material for a medical implant comprises a polymer such as UHMWPE and a surface active agent that is not covalently bonded to the polymer. The bearing material has a reduced wear rate. Also disclosed is a method of reducing the wear rate of a polymeric bearing material of a medical implant when it articulates against a hard counterface in the presence of synovial fluid, the method comprising providing a surface active agent in the synovial fluid in close proximity to the bearing surface, the hard counterface, or both.
