International ClassA61F 005/00AbstractAn adjustable knee support is formed from a single piece of a resilient, flexible laminate, preferably a layer of neoprene bonded to a nylon outer casing and a nylon inner lining. A central portion of the support overlies the patella. Upper and lower fasteners are integral with the central portion above and below the knee. Each fastener includes at least one strap that extends laterally and wraps around the leg. The upper and lower fasteners extend in opposite directions. The central portion has a separate pair of fastening straps which extend transversely from both sides and meet behind the knee cap. Tabs carrying an array of hook-type fastenings are secured to the free end of each strap. The upper and lower straps are separated from the central fastener by a cutout portion of sufficient vertical height to allow the support to flex without the buckling or rubbing the back of the leg. By pulling each of the straps separately and then securing the tab on the outer casing it is possible to adjust the degree of compression at each of the three vertical locations independently.Other References
