Abstract
A prosthesis system for replacing a knee joint between a femur and a tibia can include a first femoral component including a first condylar portion, a second condylar portion, a first sidewall extending superiorly from the first condylar portion and a second sidewall offset from the first sidewall a first distance and extending superiorly from the second condylar portion. A tibial component can have a bone engaging inferior surface and a bearing engaging superior surface. A bearing can have an inferior surface that engages the bearing engaging surface and a superior femoral engaging surface. The bearing can define an opening and a bearing keyway. A first yoke and a second yoke can each have an inferior portion, a superior portion, and a yoke keyway extending therethrough.
