Abstract: A knee joint prosthesis includes a femoral component having spaced condylar bearing portions, an anterior intercondylar portion, a posterior intercondylar portion, an intercondylar opening, and a tibial component having spaced bearing surfaces for supporting the bearing portions of the femoral component, and a relatively low intercondylar eminence between the bearing surfaces. The eminence has a peak which defines the highest portion of the tibial component, as measured relative to the tibial plateau. The peak extends into, but not through, the intercondylar opening, such that resection of the femur to provide clearance for the opening and the eminence is not required. The tibial component comprises a base and insert. The insert is preferably a non-metallic pad having the bearing surfaces and eminence formed on a superior surface thereof.
