A patella strap is a small, adjustable band designed to be worn just below the kneecap (patella). This device provides targeted compression to alleviate discomfort associated with conditions such as Patellar Tendinitis, often called Jumper’s Knee. This guide provides instructions on the correct fitting and usage. Remember, this information is not a substitute for professional medical advice; consult a healthcare professional for persistent pain.
How the Patella Strap Works
The patella strap functions by applying targeted pressure to the patellar tendon, the thick band connecting the kneecap to the shinbone. This mechanical compression alters the distribution of force across the tendon, effectively reducing the strain and helping to offload tension from the painful insertion point. This pressure reduces stress on the tendon during activities like running and jumping by slightly decreasing the patellar tendon length. The compression may also provide proprioceptive feedback, enhancing awareness of the knee’s position during movement. This biomechanical shift provides support and stability, allowing for activity with minimized discomfort.
Precise Placement and Tension Adjustment
Correct placement is the most important factor for the strap’s effectiveness, as it must sit directly over the patellar tendon. Locate the bottom edge of your kneecap. The strap, especially if it includes a padded section, should be positioned in the soft groove immediately below the kneecap, typically about one inch down. This location places the strap directly over the patellar tendon, just above its attachment point on the shinbone, known as the tibial tuberosity.
Once the strap is centered, secure the fastening mechanism, which is usually a hook-and-loop closure. The goal is to achieve a snug fit that applies firm, even pressure without causing discomfort or restricting circulation. A practical way to check for proper tightness is to use the two-finger test, ensuring you can comfortably slide one to two fingers underneath the strap.
The strap should feel supportive and secure enough that it does not slide down your leg during activity. If you experience numbness, tingling, or a throbbing sensation, the strap is too tight and must be immediately loosened. After the initial fitting, bend and straighten your knee a few times to confirm the strap remains in position and provides consistent support without pinching the skin.
Troubleshooting Common Wearing Errors
A frequent error is positioning the strap too high (resting on the kneecap) or too low (sitting on the shinbone). If worn on the kneecap, it will not provide the targeted compression needed to offload the patellar tendon and can cause irritation. Conversely, if placed too far down, it lacks the necessary leverage to modify the forces acting on the tendon.
Wearing the strap too tightly is another common mistake, which can lead to symptoms like numbness or tingling in the lower leg, indicating possible restricted blood flow or nerve compression. The tension should provide firm support, but never cause pain or severe discomfort. Furthermore, the strap should generally only be worn during the physical activities that cause pain, such as running or jumping.
Relying on the strap for all-day use or during periods of rest is not recommended, as it is designed to manage symptoms during load, not as a permanent solution. It is also important to check the back of the knee while moving, ensuring the material does not bunch up uncomfortably, which can happen with certain strap designs. Persistent pain or discomfort while wearing the strap indicates a need for professional consultation.
