SPECIFICATION ABSTRACT OF THE DISCLOSURE A knee joint prosthesis comprises a femoral component having laterally spaced-apart condylar portions shaped to match generally the shapes of the condylar surfaces of the femur and a tibial component having a plate-like platform portion which includes laterally spaced-apart concavities in the external surface, each of which receives and supports one of the condylar portions of the femoral component in all positions of the leg. The femoral component has a box-like intercondylar portion interconnecting the condylar portions and defining an intercondylar recess which receives a post that extends upwardly from the tibial component. At and near full extension of the leg, any tendency for posterial dislocation of the femur results in engagement between the anterior surfaces of the post and recess to prevent posterial dislocation of the femoral component relative to the tibial component. At leg flexions approaching full flexure, the posterior surface of the recess engages the posterior surface of the post in the event of a tendency toward anterial dislocation -1- 1627 23428 of the femur, thereby preventing anterial dislocation. Large antero-posteriormovements and dislocation are prevented in all leg positions by engagement between surfaces of the post and recess. The post and recess are shaped and dimensioned to permit essentially normal rotation and lateral angulation of the prosthetic joint in all positions.
