An artificial joint, generally, can have natural load transfer capabilities. The joint includes a first component having a first articular surface and a rotation device, and a second component having a second articular surface for mating with the first articular surface and a rotation device receptacle. The first component is matable to the second component through cooperation of the rotation device and the rotation device receptacle. The first component can cooperate with the second component in contact of the first and second articular surfaces and in articulation of the joint when the first component is mated to the second component. The joint can be embodied as a knee prosthesis; therein, the first and second components are femoral and tibial components, respectively, with the first articular surface being termed a condylar surface and the second articular surface being termed a condylar mating surface. The joint, especially the rotation device, may be made of metal. The joint may be implanted in suitable bone stock as a prosthesis.
