A prosthetic system (100) for use as a partial unicompartmental artificial knee replacement system. In one form, an artificial femoral bearing component (120) is implanted along with a floating meniscus component (110) that is configured to cooperate with the femoral bearing component to move through a plurality of translational and rotational positions as the knee rotates through a variety of angles. In another form, an artificial tibial bearing component (1220) is implanted along with a floating meniscus component (1210) that is configured to cooperate with the tibial bearing component to move through a plurality of translational and rotational positions as the knee rotates through a variety of angles.
