Abstract
A knee orthosis in which the lateral and medial hinges are articulated asymmetrically. The medial hinge, having a first variable axis of rotation, has a first pair of parallel concentric shells in the shape of the segment of a sphere defining a first opening between them, fastened to the medial portion of the thigh cuff, and three rivets, forming a first equilateral triangle having a center coincident with the first variable axis of rotation, fastened to each shell. The medial hinge also has a first shell in the shape of a segment of a sphere designed to be inserted into the first opening, fastened to the medial portion of the shank cuff and three grooves to receive the three rivets. The lateral hinge, having a second variable axis of rotation, has a second pair of parallel concentric shells in the shape of a segment of a sphere defining a second opening between the shells, fastened to the lateral portions of the thigh cuff, and three rivets, forming a second equilateral triangle having a center coincident with the second variable axis of rotation, fastened to each shell. The lateral hinge also has a second shell in the shape of a segment of the sphere designed to be inserted into …
