ABSTRACT A femoral component base having a pair of laterally spaced apart condylar portions, each of which has an external surface that is smoothly convexly curved anterior-posteriorly to match generally the distal profile of the anatomical femoral condyle and smoothly convexly curved laterally throughout its antero-posterior extent. The external convexly curved surfaces engage the tibial component having a platform portion laterally with spaced apart concavities, each of which would receive one of the condylar portions of the femoral component to allow antero-posterior rotation between the components during use of the joint. The femoral component includes a modular member having adjustable plates for adjusting the position of the femoral component in response to bone condition discovered during surgery. The tibial, femoral and modular components further include a triangular, ramp post and corresponding confined recess to limit flexion and undesirable lateral movement.
