Abstract

An orthopedic device is arranged for dynamically treating the knee. The device includes a hinge assembly, a frame having an upper cuff and a lower cuff spaced apart from and connected by the hinge assembly, and a dynamic shell connected to the frame and extending along the first side of the brace. An adjustment system is connected to the dynamic shell and includes a tensioning element operatively engaging the shell and the hinge assembly. The adjustment system is arranged to increase and decrease tension in the tensioning element. The dynamic shell is arranged to be drawn toward the frontal plane as the orthopedic device goes from an extension orientation to a flexion orientation.
