The Iliotibial band isn’t a muscle however a fibrinous band. It is on the surface of the thigh from the top of the iliac crest (hip bone), down the side of the thigh and attaches to the outside of the tibia (shin), just under the knee. The Iliotibial band helps keeps the knee stable and aids in flexion of the knee joint, It’s the quadriceps muscles assistant.
The Tenosr Fasciae Latae (TFL) muscle is located on the top of the outer thigh and the Iliotibial band attaches to it at the top of the hip bone, to form a continuous strip that runs along the side of the leg. The tensor fasciae latae movement actions are to abduct the thigh or allow the thigh and leg to move in a lateral motion. Standing with your feet together and raising your leg out to the side in the frontal plane, this is the action of the TFL. The tensor fasciae latae also aids the hip flexors (iliopsoas) in flexion of the hip or thigh.
