In order to determine the nature and magnitude of the loads developed during kneeling by persons with transfemoral amputation, and to investigate the influence of various prosthetic parameters, an analysis of the results of 162 tests in prosthetic knee hyperflexion was undertaken.
Although wearing a transpelvic or hip disarticulation prosthesis may be cumbersome, when fitted within a few weeks of amputation, the initial acceptance rate appears to be similar to that for transfemoral amputation. Immediate postoperative fitting is technically feasible but rarely performed today. Long-term wearing rates increase significantly when sockets are comfortable, flexible, and carefully aligned. In view of the magnitude of loss at this level, application of newer, sophisticated joint and foot mechanisms is often helpful. Every case requires review on its own merits; careful attention to socket design, components, and alignment ultimately determines the effectiveness of the prosthesis.
The Transfemoral Amputation, ..
An amputation that occurs through the femur is a transfemoral or above knee Suspension of the prosthesis and comfort also become an issue at this level.
