摘要：
A femoral component for a knee joint prosthesis includes a body having an anterior side, a posterior side, a pair of laterally spaced condylar portions, and an intercondylar portion joining the condylar portions and including an intercondylar recess. The intercondylar portion includes an arcuate shaped roof that is tangent to and extends between a pair of opposing side walls, and the arcuate shaped roof is defined by a single radius. The body has a cam surface located adjacent the intercondylar recess on the anterior side. The cam surface is defined by an at least substantially concave radius of curvature and a convex radius of curvature perpendicular to the concave radius of curvature so as to form a saddle shaped cam surface that is configured for articulation with a tibial insert.
