Iliotibial Band Syndrome

The Iliotibial band is a thick tendon that inserts on the outside of your knee. The function of the Iliotibial band is to help slow movement and torque at your knee during impact. Iliotibial band syndrome is a common cause of knee pain in runners. The cause is repetitive trauma to the Iliotibial band insertion on the outside of the knee resulting in tendonitis and severe lateral knee pain while running.
