ABSTRACT:
A dynamically shiftable knee brace is used to counteract anterior tibial displacement caused during leg extension by the quadriceps muscle when the anterior cruciate ligament is missing or damaged. The brace includes pairs of rigid thigh and calf support members which extend along and are strapped to thigh and calf portions of the leg, the support member pairs being pivotally connected at their inner ends to one another by a pair of specially designed hinges positioned on opposited sides of the knee. As the leg is extended from a flexed position toward its fully straightened position the hinges cause a relative anterior-posterior shift between the support member pairs in a manner creating a shear force across the knee which is opposite that generated by the quadriceps muscle. The connection strap system is operative to substantially prevent distal brace shift along the leg, and may also be adjusted to cause selective lateral or medial flexion of the calf support members relative to the thigh support members in response to leg extension.
