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 32):
The orthopaedic knee prosthesis of  claim 29 , wherein the condyle surface contacts the bearing surface at a plurality of contact points between the first contact point and the second contact point when the femoral component is moved from the first degree of flexion to the second degree of flexion, and each contact point of the plurality of contact points is defined by a ray extending from a common origin to the respective contact point of the plurality of contact points, each ray having a length defined by the following polynomial equation:\n r \u03b8 =( a +( b *\u03b8)+( c*\u03b8 2 )+( d*\u03b8 3 )), wherein r \u03b8  is the length of the ray defining a contact point at \u03b8 degrees of flexion, a is a coefficient value between 20 and 50, and b is a coefficient value in a range of 0.00<b<0.30, wherein (i) c is a coefficient value between \u22120.010 and 0.00 and (ii) d is a coefficient value between \u22120.00015 and 0.00.
