Runners Knee / Ilio-Tibial Band Friction Syndrome (ITBFS) The Iliotibial Band is a long band of fascia that runs from the outside of the hip, along the outer thigh and to the side of the knee. Ilio-Tibial Band Friction Syndrome (ITBFS) occurs when an overly tight Iliotibial Band rubs on the outer part of the knee and causes the fascial band to become inflamed through over-friction. Also, between the IT Band and the bony outer knee lies a bursa, (a lubricated pad which is there to help prevent over-friction of the IT Band as mentioned above), which can become entrapped by the IT Band and become inflamed itself. Symptoms ITBFS is characterised by pain, tenderness and swelling on the outer part of the knee and thigh. It is generally aggravated by movement of the knee, and relieved by knee inactivity. Causes ITBFS is generally considered to be an overuse condition; so a repetitive activity like running is commonly related. Repetitive loading of the knee, e.g. running or cycli
