<p>A knee replacement system includes a proximal tibial posterior camming portion defined by a first radius of curvature (152) with a first origin (154) in a first medio-lateral plane, a distal tibial posterior camming portion defined by a second radius of curvature (184) with a second origin (186) in a second medio-lateral plane, an anterior femoral camming portion of a posterior cam defined by a third radius of curvature (158) with a third origin (160) in the first medio-lateral plane, and a posterior femoral camming portion of the posterior cam and defined by a fourth radius of curvature (188) with a fourth origin (190) in the second medio-lateral plane, in which the second origin is closer to the lateral tibial portion than the first origin, or the fourth origin is closer to the medial femoral portion than the third origin.</p> |
