Iliotibial band syndrome (ITBS) is the second most common knee injury, and is caused by inflammation located on the lateral aspect of the knee due to friction between the iliotibial band and the lateral epicondyle of the femur. [2] Pain is felt most commonly on the lateral aspect of the knee and is most intensive at 30 degrees of knee flexion. [2]
The iliotibial tract or iliotibial band (ITB; also known as Maissiat's band or the IT band) is a longitudinal fibrous reinforcement of the fascia lata. The action of the muscles associated with the ITB ( tensor fasciae latae and some fibers of gluteus maximus ) flex, extend, abduct, and laterally and medially rotate the hip.
The Ober test is used in physical examination to identify tightness of the iliotibial band (iliotibial band syndrome). During the test, the patient lies on his/her side with the unaffected leg on the bottom with their shoulder and pelvis in line. The lower hip and knee can be in a flexed position to take out any lordosis of the lumbar spine. [1]

This occurs as the iliotibial band changes from a knee flexor to extensor around 30°. Again, the affected knee should be compared the normal side to rule out a false positive test.

The iliotibial tract may be irritated where it passes over the anterior superior iliac spine in iliotibial band syndrome. [3] The line around anterior superior iliac spine is sometimes called the panty line or "bikini line". [8] It is considered to be a "discreet" location for concealing cosmetic surgery scars and ports. [9]
The more common lateral extra-articular type of snapping hip syndrome occurs when the iliotibial band, tensor fasciae latae, or gluteus medius tendon slides back and forth across the greater trochanter. This normal action becomes a snapping hip syndrome when one of these connective tissue bands thickens and catches with motion.
Other causes of trochanteric bursitis include uneven leg length, iliotibial band syndrome, and weakness of the hip abductor muscles. [1] Greater trochanteric pain syndrome can remain incorrectly diagnosed for years, because it shares the same pattern of pain with many other musculoskeletal conditions.
