Iliotibial band

Last revised by Calum Worsley on 26 Oct 2022

The iliotibial band (ITB) is a thick band of fascia formed proximally at the hip by the fascia of the gluteus maximus, gluteus medius and tensor fasciae latae muscles. 

The band consists of deep and superficial layers:

  • the superficial layer is the main tendinous component and inserts onto Gerdy's tubercle on the anterior lateral tibia
  • the deep layer inserts on the intermuscular septum of the distal femur 

A small recess exists between the lateral femoral epicondyle and the iliotibial band, which contains a synovial extension of the knee joint capsule (lateral synovial recess) 1-4.
