This is a stable hybrid brace with completely adjustable thigh part and a circular lower part that makes it suitable for patients with conical thighs. The brace is fitted with our new MR4997 Active Hinge, made from A6061 aluminium, which can be adjusted in extension and flexion by using injection moulded stops. The hinge can be adjusted in the following degrees; Extension 0°, 10°, 20°, 30° and 40° and Flexion 45°, 60°, 75° and 90°. The hinge covers have a special design which makes it possible to adjust the range of motion when the hinge is fitted in the brace. The covers are open on the back side and can slide forward or backward to access the opening in the hinge. The hinge pockets are made from the new carbon-nylon material that provides a low profile and excellent durability. The hyper extension strap in the back of the brace has a low profile and can be adjusted in the front by micro hook tabs. The thigh and shin part of the brace are fitted with adjustable non elastic straps. The inside of the thigh part has an integrated friction system that prevents migration during activity. The knee fold has the breathable Neptune material for optimal comfort. The closure over the thigh and calf are made from micro hook and loop.
