Doctor's Notes on Iliotibial Band Syndrome (IT Band Syndrome)

Iliotibial band (IT band) syndrome is a condition resulting from inflammation of the iliotibial band, a band of fibers that begins at the iliac crest in the pelvis and runs on the outside part of the thigh until it attaches into the tibia (shinbone). The IT band helps stabilize the knee joint. IT band syndrome is typically caused by overuse and often occurs in long-distance runners. 

Signs and symptoms of IT band syndrome include pain on the outside of the knee. Other associated symptoms can include tenderness of the knee joint, radiation of pain to the hip, and worsening of the pain with the heel strike of walking or running. Walking up and down stairs can also cause the pain.
