Iliotibial Band Syndrome Condition
Iliotibial band friction syndrome is an overuse injury caused by repetitive friction of the IT band across the lateral epicondyle of the femur. It is a well-recognized cause of knee pain in runners so it is commonly called “runners knee”. This condition is not unique to runners. It is seen in cyclists, weight lifters, skiers, and soccer players. The iliotibial band extends from the pelvis across the lateral aspect of the knee. When this region becomes inflamed, the tenderness is usually on the lateral aspect of the knee. With a pronated foot, excessive tibial internal rotation increases and the IT band is dragged across the lateral epicondyle of the femur to its insertion on the proximal tibia. As the knee is repeatedly flexed as in running, the iliotibial band can be aggravated by gliding across the lateral aspect of the femur. In a supinated foot or people with genu varum (bow legs) the iliotibial band is placed on a stretch. A custom molded biomechanical orthotic can balance the foot mechanics reducing the irritation or stretch in the iliotibial band.
