    摘要： An orthopaedic knee prosthesis includes a tibial bearing and a femoral component configured to articulate with the tibial bearing. The femoral component includes a posterior cam configured to contact a spine of the tibial bearing and a condyle surface curved in the sagittal plane. The radius of curvature of the condyle surface decreases gradually between early-flexion and mid-flexion. Additionally, in some embodiments, the posterior cam of the femoral component may include a concave cam surface and a convex cam surface.

    摘要： An orthopaedic knee prosthesis assembly includes a plurality of femoral components. Each component includes a medial condyle and a lateral condyle. When each component is viewed in a coronal plane extending through a distal-most point of the medial condyle and a distal-most point of the lateral condyle, the medial condyle has a medial curved distal-most surface that includes the distal-most point, and a width is defined between the distal-most points of the medial condyle and the lateral condyle. The coronal radius of the distal-most surface of a first component is proportionally greater than the coronal radius of a second component. The coronal radius of the second component is proportionally greater than the coronal radius of a third component. The first component width is proportionally greater than the second component width, and the second component is proportionally greater than the width of the third component.
