For protection from patellar pain and muscle tension, the Mueller Jumper’s Knee Strap is designed to relieve the pain and provide extreme comfort. Runners and jumpers very commonly use this design. It comes in a variety of colors for you to choose from. It is built to help improve the patellar targeting. The strap slowly and steadily puts pressure on the patella tendon giving it enough compression to heal it quickly. The strap is adjustable, so it is easy to carry around and adjust to the size of your knee. What it does in technicality is, it cups the knee in a position that the tendon is relieved and does not experience much pain or pressure upon action.
