Abstract:
A knee orthosis comprising a top portion to be secured at a patient's thigh and a lower portion to be secured at the patient's lower leg, a joint portion connecting the top and lower portions, and strap means for securing the orthosis, wherein the joint portion has two axes and prevents hyperextension, and wherein the joint portion comprises two hinges connected together by a connection bar positionable in or near the popliteal space, said connection bar having at least one first stop surface, wherein said top portion and lower portion each comprise a brace member, said brace members each having at least one second stop surface which engages said at least one first stop surface of said connection bar to inhibit hyperextension beyond a first predetermined angle and to inhibit bending of the leg to less than a second predetermined angle, said brace members further having ventral slits and dorsal slits for receiving said strap means and, at least one of said ventral slits being positioned at a different height relative to one of said dorsal slits, so that said strap means connecting said brace members exert forces thereon, producing torque acting on said brace members.
