    摘要: A total knee implant prosthesis is disclosed. The total knee implant prosthesis includes a tibial component including a pair of bearing surfaces and a post positioned between the bearing surfaces, and a femoral component configured to rotate relative to the tibial component. The femoral component includes a pair of condyles sized and shaped to articulate on the bearing surfaces and a cam positioned between the pair of condyles. The cam engages the post at a first contact point when the femoral component is at 0 degrees of flexion and engages the post at a second contact point located lateral of the first contact point when the femoral component is at a first degree of flexion greater than 0 degrees. The cam is disengaged from the post when the femoral component is at a second degree of flexion greater than the first degree of flexion.
