摘要：
Knee prosthesis includes a femoral component adapted to fit on a distal end of the femur and a tibial insert component. The femoral component includes a measured anterior/posterior dimension defined by the posterior condyle surface and the interior surface of the anterior flange and a distal peg provided on a distal bone facing surface of each of the lateral and medial condylar structures, wherein the distal pegs are positioned at a midpoint of the measured anterior/posterior dimension. The implant system provides two distinct sizing segments and the tibial insert has a medial tibial aspect ratio of 0.74 and a lateral tibial aspect ratio of 0.65 to 0.68 for all sizes.
