Why It's Often Confused
Runner's Knee sits in the same body region as several other running injuries. The wrong call can turn a 2-week recovery into a 2-month one.
Runner's Knee vs Patellar Tendonitis
Patellar tendonitis hurts on the tendon below the kneecap, especially with jumping; PFPS hurts around the kneecap.
Runner's Knee vs Meniscus Tear
Meniscus pain often involves swelling, locking, or a specific twisting injury — PFPS is gradual and load-related.
When to Get Imaging
If pain is pinpoint, worsens at rest, wakes you at night, or persists more than 2-3 weeks despite reduced training — see a sports medicine clinician for imaging. Don't wait it out.
