A femoral component for a knee prosthesis comprises a reduced wear polyethylene (RWPE). Preferably all of the femoral component is the RWPE and/or at least one condylar surface of the femoral component is the RWPE. The use of RWPE instead of conventional metal components reduces or eliminates complications associated with the use of metal such as fracture (mostly at the area of the bone-metal interface), mechanical failure, and metallosis. Use of the RWPE gives a prosthesis with long life, especially with respect to wear of the femoral component. |
