A contusion, or direct force, can occur anywhere on the body, especially during contact sports or a bad fall. The quadriceps muscle group along the front of the thigh is a combination of four muscles that come together to extend the knee. After a hard hit, the muscle group will become tender and painful. If left untreated, the muscle can potentially develop myositis ossificans, or a calcification of a portion of the quadriceps. BioSkin Compression Sleeves and Shorts treat contusions with pain-relieving compression that promotes blood flow to the area, speeding recovery and enhancing performance.
