Abstract
A unicondylar femoral prosthetic implant component for implant at a prepared implant site within a natural knee joint provides a femoral articular surface having a convex surface contour configuration along a femoral condylar surface in a restored knee joint. A relief section is located adjacent the anterior end of the femoral condylar surface for placement contiguous with the patella track of the natural knee joint. The relief section has a surface contour configuration dimensioned and configured for providing an essentially continuous and smooth transition between the patella track along the natural bone adjacent the implant site and the femoral condylar surface of the implant component. The surface contour configuration of the relief section preferably is concave.
