What is Iliotibial Band Syndrome?

Iliotibial band syndrome, otherwise known as IT band syndrome, results in pain on the outer side of the knee. It tends to affect athletes who run long distances, in addition to those who take up exercise after a long break. The iliotibial band runs down the outside of your thigh as a long, thick band of tissue. It spans the area between the hip bones and the shins.

When bending or extending the leg, the iliotibial band glides over the lower edge of the femur bone. When used repeatedly for long periods of time, this movement can lead to irritation in the tissues of the thigh, which causes pain.

While Iliotibial Band Syndrome often occurs in distance runners, anyone can suffer from this condition.
