The iliotibial band is a reinforcement of the tensor fascia lata muscle, coming from the hip, going all the way down the thigh, attaching at the outside side of the knee. Pain usually occurs when running downhill or on the same surface over a longer period of time. Through the constant rubbing of this band of tissue, the IT band tightens, pain intensifies until a point when running gets nearly impossible and simple bending and extending of the knee is painful.
– Swelling and pain at the outer knee
– Differentiate between knee and ITB problem: bend knee 45 degrees→ ITB problem pain on the outside of the knee aggravates
Symptoms occur when the iliotibial band is sliding repeatedly over the lateral epicondyle (Fredericson and Weir, 2006), typically with runners in a phase of overtraining and an underlying weakness of the hip abductor muscles.
Management of this condition involves the RICE regime and activity modification in the acute phase; followed by correction of abnormal biomechanics and unleveled training techniques. However, essential is the correction of the biomechanical imbalance in order to get a long term solution; strength training and postural education play a major role.
