ILIOTIBIAL band syndrome (ITBS) is the most common cause of lateral knee pain in runners, occurring with a reported incidence as high as 12% in runners and resulting in many people stopping, or certainly interrupting their training.
It presents as pain around the outside of the knee and it was thought to be due to the ‘band’ flicking over the lateral part of the femur (thigh bone).
Often worse when the knee is flexed and extending, it can cause problems driving and climbing stairs. Usually the knee does not swell and certainly does not give way, or lock in position.
Pain can be worse after a run, or it can stop you midrun.
