<p>A femoral component (12) base having a pair of laterally spaced apart condylar portions (14, 16), 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 (13) component having a platform portion (17) laterally with spaced apart concavities (39, 41), each of which would receive one of the condylar portions (14, 16) of the femoral component to allow antero-posterior rotation between the components during use of the joint. The femoral component (12) includes a modular member (40) having adjustable plates (70) 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 (60, 61, 62), ramp post and corresponding confined recess to limit flexion and undesirable lateral movement.</p> |
