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 posterior cam of the femoral component may include a concave cam surface and a convex cam surface.
