<P>PROBLEM TO BE SOLVED: To provide an implant articular surface wear reduction system for improving orthopedic prosthetic joint longevity by reducing frictional abrasive wear. <P>SOLUTION: The implant articular surface wear reduction system includes a polymeric implant component and a rigid implant component. A hard wear layer is attached to the polymeric implant. The hard wear layer represents one opposing articular surface of a joint. The rigid implant component has a working surface and may represent another opposing articular surface in the joint. In one embodiment, the rigid implant component and the hard wear layer are ceramic. In another embodiment, a non-metallic wear layer is attached to the working surface. The non-metallic wear layer represents another opposing articular surface of the joint. In one embodiment, the polymeric implant component is a tibial implant and the rigid implant component is a femoral implant and the non-metallic wear layer is a polymer, such as polyethylene, self-reinforced polyphenylene, or PEEK. <P>COPYRIGHT: (C)2009,JPO&INPIT |
