Runner's knee — patellofemoral pain syndrome (PFPS) — is the most common running injury, affecting up to 25% of runners annually. The patella tracks poorly through the femoral groove, irritating cartilage and surrounding tissue. PEMF therapy reduces patellar inflammation and supports cartilage health. Always alongside hip and quad strengthening — the underlying biomechanical problem.
Quick facts
- Annual incidence in runners: Up to 25%
- Cause: Patellar maltracking, weak hip abductors
- PEMF role: Reduces inflammation, supports cartilage
- Always with: Hip + quad strength, gait analysis
- Recovery: 6–12 weeks typical
Why this injury happens in this sport
Weak hip abductors → knee valgus → patellar maltracking. Common in runners who suddenly increase volume, hill work, or run on cambered roads.
Recovery and return to sport
Reduce running volume by 30–50% during loading phase. Hip strengthening (clams, side-lying leg raises, monster walks) is the foundation. PEMF 2× per week for 6 weeks reduces inflammation and accelerates return.
Contraindications
Standard PEMF contraindications: pacemakers, defibrillators, cochlear implants, insulin pumps, electronic implants; active malignancy without specialist clearance; pregnancy (over the abdomen); active infection; epilepsy without GP clearance.
Frequently asked questions
Is PEMF better than KT tape?
Different tools. KT tape can briefly improve comfort during runs. PEMF addresses underlying inflammation. Use both alongside strength work.
Will running ever feel right again?
Yes for the vast majority — once hip abductor strength returns. Don't skip the strength work.
