Abstract

The patent describes a leg prosthesis for adaptation to the stump of the upper leg, which is comprised of an adapter for a knee joint, a knee joint attached to it and a prosthetic lower leg coupled to the knee joint with a prosthetic foot coupled to it. It can be swiveled into the heel position, wherein the knee joint is designed so that when it moves from the extended position into the bent position, it makes a combined rolling/sliding movement on a swivel axis, in such a way that the distance from a point in front of the swivel axis when seen dorsally to the end of the prosthetic lower leg steadily decreases and from a point in front of the swivel axis seen ventrally to the end of the prosthetic lower leg steadily increases.
