Sinding-Larsen-Johansson Syndrome | Stretches Taping + Supports for Knee Cap Pain

Are you a teen athlete with pain under your kneecap after running, jumping, or training? You might think it’s just “growing pains” — but it could actually be Sinding-Larsen-Johansson Syndrome (SLJ), a common overuse injury that affects the lower part of the kneecap during growth spurts. In this video, Physiotherapist Daniel Lawrence breaks down exactly what SLJ is, how to tell it apart from Osgood-Schlatter’s and patellar sleeve fractures, and the 3 key steps to recover fast so you can get back to sport safely.

It’s common in active teenagers who run, jump, or play sports like football, basketball, or tennis. Pain = just below the kneecap Gradual onset (not one single injury) Gets better with smart rest, stretching, and strengthening. If you can’t straighten your knee, notice swelling, or the pain started after one big landing or fall — that might be a patellar sleeve fracture, which needs a doctor’s assessment.
