The Pro-tec Athletics Patellar Tendon Strap provides compression on the patellar tendon, helping spread pressure uniformly across the patellar tendon, reducing discomfort and irritation. This compression may also help stabilize your patella, improving its tracking. In addition, Knee Pro-Tec absorbs stress to the knee, reducing vibrations in the femoral groove. The patellar tendon strap is useful for alleviating moderate knee pain, especially in areas under and surrounding the knee cap. The strap is made from neoprene, which stretches, allowing it to stay comfortably in place.
