A posterior cruciate ligament retaining knee implant prosthesis (100) comprises a femoral component (102) including a medial condyle (112) and a lateral condyle (114) separated from one another by an intercondylar channel (110) 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 (126). A tibial component (104) includes a medial condyle receiver (160) having a medial condyle receiver bearing surface, and also a lateral condyle receiver (162) having a lateral condyle receiver bearing surface. The tibial component includes an anterior post (128).
