  • POSTERIOR STABILIZED KNEE PROSTHESIS
    Publication number: 20110118847
    Abstract: A knee joint prosthesis includes a femoral component having an anterior side, a posterior side, a pair of laterally spaced condylar portions, and an intercondylar portion joining the condylar portions and including a recess. A cam surface is located adjacent the intercondylar recess on the anterior side of the femoral component and has a saddle shape that is defined by an at least substantially concave first radius of curvature and a convex third radius of curvature that is perpendicular to the concave first radius of curvature. The prosthesis also includes a tibial component including a platform having an upper surface that includes first and second laterally spaced concavities. Each concavity is adapted for receiving one condylar portion of the femoral component. The tibial component has a tibial post for reception in the intercondylar recess of the femoral component.
