IT band syndrome (ITBS) is the leading cause of lateral knee pain in runners. Irritation where the iliotibial band crosses the outside of the knee can derail training if ignored.
01Symptoms & Diagnosis
ITBS presents with:
- Sharp or burning pain on the outside of the knee, often after a few miles.
- Tenderness when pressing just above the knee joint.
- Discomfort that worsens running downhill or after sitting long periods.
- Pain that eases with rest but returns quickly when running resumes.
02Common Causes
- Rapid increases in mileage or downhill running.
- Weak hip abductors allowing the knee to collapse inward.
- Excessive foot pronation or worn-out shoes.
- Running on banked surfaces or always on the same side of the road.
03Immediate Care
Address symptoms early:
- Rest: Reduce or stop running to calm irritation.
- Ice: 10–15 minutes after activity to manage inflammation.
- Stretch: Gentle IT band and hip stretches for relief.
- Anti‑inflammatories: As advised by a medical professional.
04Rehab & Strength
Build resilience with progressive loading:
- Side‑lying leg raises and clamshells to strengthen the hip abductors.
- Single‑leg squats and step‑downs focusing on knee alignment.
- Foam rolling along the outer thigh to reduce tightness.
- Short bouts of easy running, increasing distance only when pain‑free.
05Prevention & Return
- Increase training volume gradually and vary running surfaces.
- Keep hips and glutes strong with regular strength sessions.
- Rotate shoes and replace worn pairs promptly.
- Resume running with walk‑run intervals; stop if pain persists.
If symptoms persist or worsen, consult a medical professional.
