A patellar tendon knee strap is a simple, non-invasive device used to manage pain associated with conditions like jumper’s knee (patellar tendinopathy) and runner’s knee. It works by applying targeted pressure to the patellar tendon, the tissue connecting the kneecap (patella) to the shinbone (tibia). This localized compression redistributes forces traveling through the tendon, reducing strain during physical activity. Learning the correct application technique is important to ensure the strap provides support without causing discomfort or restricting circulation.
Understanding the Patellar Tendon Strap
This supportive device is a narrow band, differentiating it from a full knee brace or a compression sleeve. The mechanism involves applying focused pressure to the patellar tendon, which is part of the quadriceps mechanism that straightens the leg. By slightly altering the angle and length of the tendon, the strap helps offload tension that builds up during repetitive movements like jumping and running. Research suggests this focused pressure may reduce strain on the overloaded tendon, helping manage discomfort. The strap works best when combined with a broader rehabilitation plan, including strengthening exercises for the surrounding muscles.
Step-by-Step Guide to Application
The physical process begins by ensuring your leg is relaxed, either fully extended or slightly bent, which makes accurate positioning easier. Identify the specific feature of your strap, such as a padded section or cushion, as this part is intended to sit directly over the tendon. Slide the circular strap up your leg from your foot, guiding it toward the knee joint.
Once it reaches the knee area, center the strap so the pressure-applying element is positioned precisely on the patellar tendon. Most straps use a hook-and-loop closure system (Velcro) for a customized fit. Wrap the strap around the back of your leg and secure the closure in the front of your knee, ensuring the material lies flat against your skin without twisting or bunching. Fastening the strap should provide a snug fit that stays securely in place without restricting movement.
Checking for Correct Placement and Tension
Correct placement is the most important factor for the strap to function as intended. The strap’s central, padded section must sit directly in the groove just beneath the kneecap, above the bony bump of the tibial tuberosity on the shinbone. This location targets the patellar tendon, redirecting force away from the insertion point.
After securing the strap, assess the tension. It should be firm enough to provide gentle pressure but not so tight that it feels constrictive. A properly tensioned strap will stay put during activity and offer support without causing numbness, tingling, or pain below the knee, which are signs of over-tightening. Bending your knee or performing a light squat can help you test the placement and confirm the strap does not slip down or roll up. If the strap shifts or causes discomfort, adjust the tension and placement until the pressure is targeted and comfortable.
