What you need to know
Iliotibial band (ITB) syndrome (ITBS) is the most common cause of lateral knee pain in runners, but may be provoked by other activities such as swimming, rowing, cycling, and hiking
Activity modification and ITB stretches can be recommended in primary care
Consider referral to physiotherapy for biomechanical and sport specific rehabilitation when severe or not responding to initial management
A 25 year old woman has recently started training for her first marathon. When she increased her typical running distance from 10 to 18 km she started getting lateral knee pain and tightness. It occurs at the same distance each time she runs, and is worse when she runs downhill.
Iliotibial band (ITB) syndrome (ITBS) affects 7-14% of runners,12 although it is associated with a variety of activities including cycling, field sports, hockey, rowing, swimming, hiking, and basketball.1 The pain or tightness typically affects the lateral knee but can radiate along the length of the ITB, presenting with hip or thigh pain (fig 1). ITBS is usually caused by biomechanical abnormalities, often combined with overtraining, although it can develop with quite modest levels of exercise. This article outlines how to diagnose ITBS in someone presenting with lateral knee pain, and offers a practical guide to initial management in primary care.
What you should cover
Understanding the location and pattern of the pain and biomechanics is important to evaluate and treat the condition. The assessment and differential diagnosis is summarised in the table .
