Iliotibial Band Friction Syndrome


Iliotibial band friction syndrome (ITBS) describes damage to the iliotibial band, the thick band of connective tissue that runs down the outside of your thigh from your hip to the top of your shin bone, as a result of the band repeatedly rubbing over a bony bump on the outside of the knee as the knee bends and straightens. 


While this condition has been poorly understood previously, recent studies suggest that it may be a layer of fat that sits between this bump and the band that may be the cause of the pain, swelling and discomfort. Regardless, the result is pain on the outside of the knee and in the area of the iliotibial band.


Causes & symptoms of iliotibial band pain


The most common causes we see are the combination of a tight iliotibial band (very common if you exercise but don’t focus on this band specifically) and overuse by repeatedly bending and straightening the knee so that the tendon is repeatedly rubbing. Overuse may be contributed to by increasing your running, walking, hiking or cycling distance or intensity, poor foot and leg biomechanics, weak muscles including the gluteals and unsupportive footwear – to name a few.


The primary symptom is pain on the outside of the knee that is exacerbated by bending and straightening the knee. Initially, you may also have some swelling, stiffness or weakness in the knee.


Treating iliotibial band friction syndrome


Like the other causes of knee pain that we see and treat, there are three important parts to treatment in order to give you long-lasting relief from your pain and avoid the recurrence of injury.


  • Treating your immediate painful symptoms
  • Repairing the damaged ITB to get it back to full strength and functional capacity, while letting the microtears heal
  • Addressing the causative factors so that the problem doesn’t continue to recur in the future
