Abstract
A prosthesis for replacing a knee joint between a femur and a tibia can include a femoral component having a first condylar portion, a second condylar portion, a first sidewall and a second sidewall that collectively comprise a first hinge portion. A tibial component can have a first engagement portion formed thereon. A bearing can have an articulating inferior surface adapted to articulate along the bearing. The bearing can have an opening. A yoke can have an inferior portion and superior portion, the superior portion having an axle that comprises a second hinge portion. The inferior portion can have a second engagement portion and be configured to at least partially pass through the opening. The femoral component is operable to rotate relative to the tibial component about a superior/inferior axis a first rotational distance until the first and second engagement portions engage each other and inhibit further rotation.
