Which of the following is used as a reference point for iliotibial band syndrome?

The greater trochanter serves as a significant anatomical landmark when discussing iliotibial band syndrome (ITBS). ITBS is commonly characterized by pain that occurs on the outer side of the knee, often due to inflammation or irritation of the iliotibial band as it passes over the greater trochanter of the femur during repetitive activities like running or cycling.

The iliotibial band itself is a thick band of fascia that extends from the hip to the outside of the knee and plays a crucial role in stabilizing the knee joint. The greater trochanter is located on the femur and acts as a point of attachment for various muscles that contribute to hip stability and movement. Because of its proximity to the iliotibial band and its role in the mechanics of hip and knee movement, any assessment of iliotibial band syndrome often includes evaluating the area surrounding the greater trochanter for signs of irritation or tightness.

The other anatomical structures mentioned—such as the acromion process, the anterior superior iliac spine (ASIS), and the coccyx—are less relevant as reference points for ITBS. The acromion process is part of the shoulder and has no direct relation to the iliotib
