ABSTRACT:
An orthopedic hinge joint mechanism to maintain knee stability and to protect the unstable and injured knee. Said hinge is comprised of two upright members articulating with two additional offset linkage pieces. This system is utilized separately or in conjunction to provide limited and controlled motion in the anatomical sagittal and frontal planes. It is covered with a flexible tubing and appropriately affixed to one or both sides of the affected limb to resolve instability of the knee due to ligamentous rupture or laxity.
