Osgood-Schlatter Disease — North Vancouver
Your kid's complaining about a sore, swollen bump just below the kneecap that flares with every soccer practice. It's a growth-plate thing, it's common, and the goal is keeping them in their sport — not pulling them out of it.
What it is
Understanding your osgood-schlatter disease.
Osgood-Schlatter is one of the most common reasons a 10-to-15-year-old turns up with knee pain. The tendon that runs from the kneecap down to the top of the shin pulls on a patch of bone that's still growing, and the spot where it attaches gets irritated, tender, and sometimes visibly swollen — a bony bump on the front of the shin that doesn't go away.
It flares with exactly the things active kids love: running, jumping, sprinting, and kneeling, and it usually eases with rest. During a growth spurt the bones lengthen faster than the muscles and tendons can keep up, so the quad and tendon end up tight and tugging harder on a growth plate that's already a soft spot. Repeated hard efforts — back-to-back practices, a tournament weekend — pile load onto that junction faster than it can settle. Boys tend to be affected a little more often than girls, and the symptoms generally settle as growth slows.
The reassuring part is what this isn't. It isn't a tear, it isn't damaging the joint, and it nearly always settles once growth finishes and the growth plate fuses. The job in the meantime is managing load so the pain stays tolerable and the young athlete keeps doing the sport that matters to them.
What to expect
Most kids feel meaningfully better within a few weeks of managing load and adding the right strength and mobility work, even though the bony bump can stick around. Symptoms tend to come and go with growth spurts and busy seasons until the growth plate finishes maturing — so the plan is about staying in sport through it, not waiting on the sidelines for it to vanish.

Common questions
About osgood-schlatter disease.
Does my child have to stop playing sport?+
Usually not entirely. Complete rest tends to mean a deconditioned, frustrated kid who flares again the moment they return. The better approach is managing the dose — easing back during heavy weeks, keeping the strength work going — so they stay in the game while the knee settles.
Will the bump on the shin go away?+
Often the bony lump stays even after the pain has gone, and that's normal — it's the bone that built up where the tendon pulled. What matters is that it's no longer sore. The pain reliably settles once the growth plate finishes maturing.
How long does Osgood-Schlatter last?+
It typically resolves on its own once growth finishes, which can be anywhere from several months to a couple of years depending on where your child is in their growth spurt. Good load management and rehab make that stretch far more comfortable and keep them in their sport.
My teen plays soccer and basketball year-round — is that the problem?+
Back-to-back jumping and sprinting seasons with no real off-period are a classic trigger, because the tendon attachment never gets a quiet stretch to settle. We don't usually tell families to quit a sport — we look at how to space the load across the calendar so the knee can keep up.
