Iliotibial Band Friction Syndrome (ITBFS)

The iliotibial band is a long tendon that runs down the outside of the thigh and inserts on the side of the knee. It provides stabilisation to the knee in the walking and running motion. With repeated bending/straightening of the knee, the iliotibial band (ITB) rubs against the prominent bone on the outside of the femur (thigh bone) at the knee.
