A posterior cruciate ligament retaining knee implant prosthesis comprises a femoral component (302) including a medial condyle (314) and a lateral condyle (312) separated from one another by an intercondylar channel (310) adapted to accommodate throughput of a native cruciate ligament. Each of the medial condyle and the lateral condyle posteriorly terminate. The medial condyle includes a medial condyle bearing surface and the lateral condyle includes a lateral condyle bearing surface. The femoral component includes an anterior cam (326). A tibial component includes a medial condyle receiver having a medial condyle receiver bearing surface, and also a lateral condyle receiver having a lateral condyle receiver bearing surface. The tibial component includes an anterior post (328).
