A knee joint prosthesis which comprises a tibial component () and a femoral component (). The femoral component has condyles () which act against the tibial component, directly or indirectly, during flexing of the knee. A cam () on the femoral component acts against a post () on the tibial component at high flex angles. The surface of the post which is contacted by the cam at high flex angles is convex when the post viewed generally perpendicular to the tibial bone contact and bearing surfaces, and the femoral bearing surface which is provided by the cam, where it contacts the convex surface of the post at high flex angles, is locally concave () when viewed along the surface of the post which contacts the cam so that the area of contact between the post and the cam is greater at high flex angles than at lower flex angles.
