Abstract: A knee brace for easing the symptoms of osteoarthritis is disclosed in which force straps provide a varying unloading force to the knee as the joint is flexed and straightened. The force straps are arranged to alter the degree of angulation between frames of the brace that span the joint, such that abstracting force is applied above and below the joint rather than to the joint itself. A dual hinge brace incorporating a push-pull hinge that alters the degree of angulation between the frames of a knee brace is also described.

Abstract: A knee brace having a femur support section pivotally connected to a tibia support section is provided. The femur support section has a medial frame and a lateral frame, sandwiched between width adjustment plates. The width adjustment plates hold the lateral and medial frames, and are held together by retainer bolts and nuts. The retainer bolts and nuts can be loosened to permit the lateral frame and the medial frame to slide against the width adjustment plates. Thus, the space between the lateral frame and the medial frame can be adjusted according to the size of the wearer's leg.
