The Cho-Pat Original Knee Strap has been aiding athletes and active individuals suffering from knee pain for over 20 years. The Cho-Pat Knee Strap provides relief from both acute and chronic knee pain associated with various knee disorders such as patellar tendonitis, chondromalacia patella, Osgood Schlatter's Disease, runner's and jumper's knee, some forms of arthritis, and knee degeneration. The strap when applied provides compression and functions dynamically as the knee bends and straightens to apply pressure on the tendon below the kneecap, which helps stabilize and guide the patella in its groove allowing for improved knee cap tracking. The patellar strap also elevates the knee slightly, further relieving the pressure, pain, and inflammation that may occur from knee disorders. Made of a Tricot-covered (1/4 inch) foam strap with Velcro closures in the back. The Original Knee Strap is available in tan or black and a variety of sizes.
