Osgood-Schlatter Disease (OSD) is a common cause of knee pain primarily affecting active adolescents during periods of rapid growth. This condition develops from repetitive stress and traction on the growth plate, or apophysis, of the tibial tuberosity, the bony bump located just below the kneecap. The constant pulling of the patellar tendon on this immature area causes inflammation and pain, particularly during activities that involve running, jumping, and squatting. Taping is a non-invasive technique to provide mechanical support, offload the affected tendon insertion, and help manage pain during physical activity.
Preparation and Necessary Materials
Successful taping begins with proper skin preparation to ensure the adhesive materials remain securely in place. Essential supplies include sharp scissors, rubbing alcohol wipes, and a clean towel. Before application, the skin must be completely clean and dry; wiping the area with alcohol removes oils or sweat that could compromise adhesion.
For the infrapatellar strap method, you need either a pre-made patellar tendon strap or a roll of 1.5-inch non-elastic athletic tape and pre-wrap. Pre-wrap protects sensitive skin from the athletic tape’s strong adhesive. The advanced support method requires a roll of water-resistant Kinesiology Tape (KT), which stretches to provide dynamic support. All edges of the tape should be rounded after cutting to prevent premature peeling.
Applying an Infrapatellar Strap
The infrapatellar strap technique aims to reduce the pulling force of the quadriceps muscle on the painful tibial tuberosity by applying focused pressure to the patellar tendon. This pressure changes the angle of the tendon, dispersing tension away from the inflamed area. If using a pre-made strap, position the central pad directly across the patellar tendon, the soft tissue space immediately below the kneecap.
If using athletic tape, first apply a strip of pre-wrap circumferentially around the leg, centered over the patellar tendon. Next, tear a strip of athletic tape long enough to wrap around the leg and overlap by about one inch. Apply this athletic tape strip directly over the pre-wrap with firm tension. Ensure the strap sits on the tendon itself, not the bony tibial tuberosity. The tightness must be sufficient to hold the skin taut without restricting blood flow or causing numbness, tingling, or discomfort.
Advanced Support Using Kinesiology Tape
Kinesiology Tape (KT) provides dynamic support that moves with the body and is often worn for multiple days. This technique uses the tape’s elastic properties to lift the skin, promoting circulation and reducing pressure on pain receptors. The most common application for OSD is a “U-shape” pattern that surrounds the area of tenderness.
Start by cutting a single strip of KT tape, approximately 8 to 10 inches long, and round the corners. Have the person sit with their knee bent at a 90-degree angle for optimal tape placement. Tear the backing paper in the center of the tape to create an application zone, leaving the ends protected.
Apply the exposed central section with a moderate stretch (50 to 75 percent) directly over the patellar tendon, just superior to the painful tibial tuberosity. Gently lay down the two anchor tails of the “U” shape without any stretch, following the contours of the sides of the knee cap. Rub the entire strip vigorously to activate the adhesive, ensuring the tape remains smooth. The finished application should create a slight lifting of the skin when the knee is straightened, providing a decompressive effect.
Post-Taping Care and When to Seek Professional Help
After applying the tape, monitor the area for signs of adverse reactions, such as skin irritation or excessive tension. If the individual experiences numbness, tingling, increased pain, or a change in skin color below the tape, the application must be removed immediately. The tape is safe to wear for up to three to five days, but remove it sooner if it becomes wet, dirty, or begins to peel significantly.
To remove the tape, peel it back slowly, pulling in the direction of hair growth while pressing down on the skin to minimize discomfort. Taping is a tool for temporary pain management during activity; it does not correct the underlying issue. If the pain persists, worsens, or is accompanied by significant swelling, redness, or an inability to bear weight, consult a healthcare professional. A physician or physical therapist can provide a definitive diagnosis and develop a comprehensive treatment plan addressing root causes like muscle imbalances or tightness.
