Abstract
A knee orthosis to prevent hyperextension having a top portion secured to a patient's thigh, a lower portion secured to the patient's lower leg and a joint portion. A connection bar of variable width connects the two hinges of the joint portion in or near the popliteal space of the patient. The connection bar, the top portion and the lower portion include stop surfaces, which inhibit hyperextension of the patient's knee beyond a first predetermined angle and which inhibits bending of the patient's knee to less than a second predetermined angle. In addition, the top and lower portions include brace members having ventral and dorsal slits vertically offset from each other in order to produce a torquing action on the brace.
