A prosthetic joint device is provided with first and second components respectively providing convex and relatively flat articulatory bearing surfaces, and a third component is located between the former components and has two surfaces which are complementary to and engage the convex and flat surfaces. Preferably the two pairs of engaged surfaces are suitably respectively spherically shaped and planar. The device can move under natural muscular and ligamentous control, in a varying manner closely simulating that of a natural joint which maintains uniform load distribution. Initial development centered on the provision of a knee joint endoprosthesis, but the mechanics of the device are well suited to other joints, particularly of non-congruous form, and also to joints in exoprostheses.
