IT BAND SYNDROME

IT BAND SYNDROME - Iliotibial band syndrome is one of the leading causes of lateral knee pain in runners. The iliotibial band is a thick band of fascia on the lateral aspect of the knee, extending from the outside of the pelvis, over the hip and knee, and inserting just below the knee. The band is crucial to stabilizing the knee during running, as it moves from behind the femur to the front of the femur during activity. The continual rubbing of the band over the lateral femoral epicondyle, combined with the repeated flexion and extension of the knee during running may cause the area to become inflamed. The iliotibial band is a thick band that begins at the iliac crest in the pelvis, runs down the lateral part of the thigh, and crosses the knee to attach into the top part of the tibia or shinbone. The iliotibial (IT) band helps stabilize the outside part of the knee through its range of motion. Iliotibial band syndrome is the most common cause of lateral knee pain in runners and bicyclists.

Prevention that includes maintaining flexibility and strength of the low back, hips, knees, and leg muscles is key to avoiding recurrence. Inflammation of the iliotibial band can occur as it travels back and forth, crossing the bony prominence of the femoral epicondyle as the knee flexes and extends. The iliotibial band runs along the lateral or outside aspect of the thigh, from the pelvis to the tibia, crossing both the hip and knee joints. The iliotibial band is an important stabilizer structure of the lateral part of the knee as the joint flexes and extends.

 Pain may be felt when bending and straightening the knee which may be made worse by pressing in at the side of the knee over the sore part. There might be tightness in the iliotibial band which runs down the outside of the thigh. Weakness in hip abduction or moving the leg out sideways is another common sign. Tender trigger points in the gluteal muscles or buttocks area may also be present.
