Patellar Tendon Strap for Osgood-Schlatter: A Guide for Parents

If your active child has a sore, sometimes swollen bump just below the knee, their doctor may have mentioned Osgood-Schlatter. It is one of the most common causes of knee pain in growing kids who play sports, and a patellar tendon strap is one of the tools families often use to keep them comfortable.

What is Osgood-Schlatter?

During growth spurts, the patellar tendon pulls on a growth area at the top of the shin bone (the tibial tuberosity). Repeated running and jumping can irritate it, causing pain and a tender bump just below the knee. It is most common between about 10 and 15 years old, often in kids who play soccer, basketball, volleyball or gymnastics. The good news: it usually settles as growth slows.

Common symptoms

• Pain at the bony bump below the kneecap.
• Pain with running, jumping, kneeling and stairs.
• A bump that may stay visible after the pain is gone.

How a patellar tendon strap is used for Osgood-Schlatter

A strap sits on the tendon just above the painful bump. Some families and clinicians use one during sport to make running and jumping more comfortable while the area settles. It does not change how the growth plate heals, so it works best as part of a plan your child's doctor or physical therapist agrees with, which usually includes:

• Adjusting training load during painful periods instead of stopping all activity.
• Strength and flexibility work for the thighs and hips.
• Ice after sport if it helps, and kneepads for kneeling sports.

Sizing tips for teens

Our patellar tendon strap is designed to fit most adults. It often fits older teens, but younger children may have legs that are too slim for a snug fit. Measure around the leg just below the kneecap and email us at hello@patellartendonstrap.com before ordering if you are unsure. Place it as shown in our placement guide: the pad goes on the tendon above the bump, not on the bump itself.

When to see a doctor

• Pain at night or at rest, or pain that keeps getting worse.
• A sudden pop, inability to straighten the knee or a limp.
• Redness, heat, fever or swelling elsewhere in the knee.
• Pain in one knee that is very different from the other.

Always confirm the diagnosis with your child's doctor before buying any support.
