Abstract:

A prosthesis for leg amputation at the knee joint or short distance above the knee is disclosed which includes an upper leg socket and artificial lower limb pivotally coupled together by a knee bracket attached to upper leg socket. The knee bracket is also pivotally coupled to a hydraulic unit carried by the lower limb. The knee bracket provides a hinge arrangement for the knee joint above the end of the amputee's leg stump by several inches thus providing a more natural looking and operating artificial limb.
