ABSTRACT OF THE DISCLOSURE A pivotal knee joint associated with an orthopedic leg brace is provided with a ratchet wheel operable to permit adjustable back and forth movement of a knee. Both upper and lower leg brace sections of the leg brace are pivotally attached to the rotatable axis of the ratchet wheel, and a pair of rotatable pawls are provided which are selectively manually operable by a user to effectively control the direction of rotation of the ratchet wheel, as well as to lock the rachet wheel and the associated leg brace against further rotation or relative pivotal movement. Depending on the positioning of the pawls, various leg muscles may then be exercised and stretched through the relative positioning of the upper and lower leg brace sections, and the knee joint having the double-locking ratchet.
