    摘要: A system and method for joint restoration by extracapsular means includes an actuator operable to apply a force to a portion of a bone to effect a change in the joint space geometry. One embodiment of the system includes an actuator operable to apply a cyclic loading to subchondral bone of a femur, wherein loads of a predetermined magnitude are alternately applied and released. Between periods of cyclic loading, rest periods are provided where no load is applied. Over time, the femoral joint surface is remodeled in accordance with the location, direction, magnitude, and frequency of the loading.
