ABSTRACT:
This invention relates to a knee support device which enables a knee brace to track closely the movement of the tibia. In use, a complete knee brace comprises two of the knee support devices of this invention, one on each side of the leg. The knee support device comprises an upper and a lower elongated brace member releasably secured to a person's thigh and leg, respectively. Each of the two brace members includes pivot means and gear means, such that the gear means of the two brace members engage each other to rotate each brace member about the pivot means of the corresponding member. The upper and lower brace members on each side of the leg are connected by a link member connecting the pivot means of the two braces. The means for securing the brace members to the leg are placed such that the pivots are anterior to the knee joint, so that the rotation of the lower brace member tracks the tibia in flexion when the person and the brace members are viewed in profile. The link member and portions of the brace members remain close to the knee joint when it is bent to provide greater support and protection for the joint.
