Abstract
A patellar component of a prosthetic knee joint includes a domed portion having a peak offset from the center of the patellar component for effecting compensation for the displacement of the mechanical joint line upon implant of the prosthetic knee joint so as to enable affixation of the patellar component within the natural patella with sufficient bone coverage while attaining appropriate sliding engagement of the patellar component with a patellar groove in the femoral component of the prosthetic knee joint during articulation of the knee.
