It is a common injury to the knee, generally associated with running, cycling, hiking or weight-lifting(especially squats).

The iliotibal band is a thick band of fascia on the outside of the knee, extending from the outside of the pelvis, over the hip and knee, and inserting just below the knee. The band is crucial to stabilizing the knee during running, as it moves from behind the femur to the front of the femur during activity. The continual rubbing of the band over the lateral femoral epicondyle, combined with the repeated flexion and extension of the knee during running may cause the area to become inflamed. Which is also why iliotibal band is most commonly affect runners.Iliotibial Band Syndrome

Common Symptoms

Patients suffering from iliotibal band are suggested to only perform their physical therapy in the presence of a physical therapist because it is often difficult for them to perform the stretching exercise effectively on their own. Some local modalities such as ultrasound and electrical stimulation to the area of tenderness on the outer side of the knee are also helpful.
