What Causes Iliotibial Band Syndrome?This is an overuse inflammatory condition due to friction (rubbing) of a band of a tendon over the outer bone (lateral condyle) of the knee. Although iliotibial band syndrome may be caused by direct injury to the knee, it is most often caused by the stress of long-term overuse, such as sometimes occurs in sports training.
What Are the Symptoms of Iliotibial Band Syndrome and How Is It Diagnosed?A person with this syndrome feels an ache or burning sensation at the side of the knee during activity. Pain may be localized at the side of the knee or radiate up the side of the thigh. A person may also feel a snap when the knee is bent and then straightened. Swelling is usually absent and knee motion is normal. The diagnosis of this disorder is usually based on the patient's symptoms, such as pain at the lateral condyle, and exclusion of other conditions with similar symptoms.
How Is Iliotibial Band Syndrome Treated?Usually, iliotibial band syndrome disappears if the person reduces activity and performs stretching exercises followed by muscle-strengthening exercises. In rare cases when the syndrome doesn't disappear, surgery may be necessary to split the tendon so it is not stretched too tightly over the bone.
