The Patellovator knee orthosis has a unique design that applies pressure to the patellar tendon without creating a tourniquet around the leg or irritating the popliteal. The Patellovator knee orthosis is able to achieve this remarkable objective by having an interlocking base strap made from Coolflex™ material which is very comfortable and flexes with the knee. The pressure on the patellar tendon is applied when the external laces are pulled which force the padded rope core onto the patellar tendon. Another surprising characteristic of the Patellovator knee orthosis is that all of this technology is incorporated into a very low profile design.
