What Is IT Band Syndrome?
Iliotibial band syndrome (ITBS) is an overuse injury causing pain on the outer side of the knee. The IT band is a thick band of tissue running from the hip to below the knee, and irritation occurs where it crosses the knee joint.1
Symptoms
- Sharp or burning pain on outer knee
- Pain typically worse with running/cycling
- Pain often starts after certain distance/time
- Worse going downhill or down stairs
- May feel snapping over knee
- Tender to touch at outer knee
Risk Factors2
- Running (esp. distance)
- Cycling
- Sudden increase in training
- Running on banked surfaces
- Weak hip abductors
- Leg length discrepancy
- Excessive foot pronation
Diagnosis
- Clinical examination
- Noble compression test
- Ober test for IT band tightness
- MRI if diagnosis unclear
Treatment3
Acute Phase
- Reduce or stop aggravating activity
- Ice
- NSAIDs
Rehabilitation
- Hip abductor strengthening (key!)
- Glute strengthening
- Foam rolling (some benefit)
- IT band stretching
- Gait analysis/modification
Other Options
- Corticosteroid injection
- PRP
- Surgery (rare, last resort)
