Abstract:
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 radius of curvature of the condyle surface may be increased during mid-flexion.

Claim (Index 29):
An orthopaedic knee prosthesis comprising:\n a femoral component including a condyle surface that is curved in the sagittal plane; and a tibial bearing including a bearing surface configured to articulate with the condyle surface of the femoral component, wherein the condyle surface of the femoral component (i) contacts the bearing surface at a first contact point on the condyle surface at a first degree of flexion, (ii) contacts the bearing surface at a second contact point on the condyle surface at a second degree of flexion, the second degree of flexion being greater than the first degree of flexion and in the range of about 0 degrees to about 50 degrees, and (iii) contacts the bearing surface at a third contact point on the condyle surface at a third degree of flexion, the third degree of flexion being greater than the second degree of flexion and in the range of about 70 degrees to about 120 degrees, wherein the condyle surface in the sagittal plane has a first radius of curvature at the first contact point, a second radius of curvature at the second contact point, and a third radius of curvature at the third contact point, the first radius of curvature being different from the second radius of curvature and the third radius of curvature, and wherein the condyle surface has a plurality of radii of curvature between the first contact point and the second contact point to transition from the first radius of curvature to the second radius of curvature over a range of degrees of flexion.
