A brace for treating knee contractures includes an inner lower arm and an outer lower arm. An arcuate strut connects the lower arms and superposes the posterior calf. The brace includes an inner upper arm and an outer upper arm. A second arcuate strut connects the upper arms and superposes the anterior thigh. A first lockable hinge connects the outer arms. A second hinge connects the inner arms. A first expansion means is situated on the first arcuate strut and is adapted to direct pressure from the strut to the calf. A second expansion means is situated on the second arcuate strut and is adapted to direct pressure from the strut to the front of the thigh. Once the one or more hinges are locked in therapeutic position, the expansion means can be expanded to provide a controlled and progressive additive stretch.
