ABSTRACT:
A knee brace has an adjustable rigid posterior strut with an arcuate member which extends through the popliteal space behind the knee joint and is made of two halves which can be extended or retracted axially or rotated with respect to one another. Terminal portions of the strut, to which supports secured to the leg and thigh are hinged, are adjustably secured by ball and socket connections to mounting members which in turn are adjustably attached to the arcuate member by stems which telescope into and rotate within bores in the ends of the two halves of the arcuate member. With these adjustments the components of the posterior strut can be locked in a myriad of configurations to accommodate for various sizes and deformities of protected joints.
