Abstract: A knee brace having adjustment mechanisms that are easy and economical to produce while being very user friendly, and which is more comfortable to wear. The brace has a joint mechanism formed of a plurality of plates with notches, openings and range of motion surfaces, the relative positions of which are used as part of a flexion-extension stop arrangement and also as part of an adjustable locking arrangement by which the brace can be locked, temporarily released or indefinitely released. Furthermore the lateral-medial angulation of the femoral strut is able to be adjusted relative to the joint mechanism and tibial strut.

Abstract: An orthopedic knee brace which will allow lateral-medial compensation to be obtained while still enabling the use of known joint mechanism which will constrain the leg to execute the correct natural movement of the knee by separating lateral-medial compensation and anterior posterior movement functions. More specifically, the present invention utilizes a pair of hinges, one of which provides for movement in a posterior-anterior plane and the other which provides for movement in a medial-lateral plane. In this way, any conventional knee joint mechanism may be employed and movement of the leg can be properly constrained to execute a prescribed motion.
