Pain around or behind the kneecap that gets worse on stairs, after sitting for a long time or running downhill. Patellofemoral pain is the most common knee problem in runners.
The steps with the best evidence:
Strengthen the hips and the muscles around the knee together
Reduce load for a while: less volume, avoid steep descents
Increasing step rate by 5-10% can reduce the load on the knee
Braces and taping can give short-term relief, but they’re not the fix on their own.
A practical way to raise your step rate: check your cadence on your watch. If it’s 160, aim for 168-170. A metronome app or a playlist with the right beat helps. You’re not running faster, your steps just get a little shorter.
