摘要：
A knee joint prosthesis includes a femoral component having an anterior side,a posterior side, a pair of laterally spaced condylar portions, and an intercondylarportion joining the condylar portions and including a recess. A cam surface islocated adjacent the intercondylar recess on the anterior side of the femoralcomponent and has a saddle shape that is defined by an at least substantially concavefirst radius of curvature and a convex third radius of curvature that is perpendicularto the concave first radius of curvature. The prosthesis also includes a tibialcomponent including a platform having an upper surface that includes first andsecond laterally spaced concavities. Each concavity is adapted for receivingone condylar portion of the femoral component. The tibial component has a tibialpost for reception in the intercondylar recess of the femoral component.
