Abstract
A knee prosthesis includes a femoral component for attachment to the condyle region of a femur in a human knee and a tibial component for attachment to the superior articular region of a tibia in the knee. The femoral component and tibial component are pivotally hinged together by a pintle. The femoral component includes a concave channel extending perpendicular to the axis of the pintle to form a patellar guide surface.
