Runner's Knee in Kids — Daily Rehab Protocol
Your kid runs, jumps, or plays sports and their knee hurts right on the front of the kneecap. That's not Osgood-Schlatter. It's runner's knee — and the fix is a different routine.

What runner's knee is
Medically called patellofemoral pain syndrome, runner's knee is pain from the kneecap not tracking properly in its groove. In kids, the root cause is almost always a combination of: weak glutes (underdeveloped hip abductors allow the knee to cave inward), tight quads pulling the kneecap off-center, tight IT band on the outside, and training volume that outpaced their conditioning.
Signs it's runner's knee
- Pain at or around the kneecap, not below it
- Pain worsens with running, squatting, or stairs (especially going down)
- Sometimes a grinding or clicking sensation
- Pain after sitting too long (“theater sign”)
- Usually both knees, not just one
The daily 5-exercise rehab routine
1. Clamshell (12 per side). Glute medius — the muscle that stops the knee caving in.
2. Glute bridge (10 reps, hold each 3 sec). Glute max activation.
3. IT band stretch (30 sec per side). Releases the lateral tension pulling the kneecap out.
4. Quad stretch (30 sec per side). Lengthens the muscles pulling on the kneecap.
5. Wall sit (30-45 sec hold). Builds quad endurance without compressing the kneecap.

- Reduce high-impact volume by 30–50% for 2–4 weeks during active flare
- Swap some sport practice for swimming or cycling
- Check footwear — worn-out shoes with collapsed arches accelerate this
- Ice after activity, 10 minutes
- Talk to the coach — more running isn't the answer
