WHAT IS ILIOTIBIAL BAND SYNDROME
(ITB Syndrome)
ITB Syndrome diagnosis is becoming more common, but just what is it?
The ITB is a strong fibrous band of tissue originating at the upper aspect of the pelvis running the length of the outside of your thigh to just below the knee. Its main function is to stabilize the knee in extension and partial knee flexion. The ITB is the main support of the outside aspect of the knee when leaning forward with a bent knee. The Gluteus Maximus and Tensor Fascia Latae insert onto the band which contribute to hip extension, flexion, abduction, medial and lateral rotation.
ITB syndrome generally occurs with repetitive bending and straightening of the knee cause friction to develop with progression to irritation and inflammation of the soft tissue including bursa, muscles and tendons. Common aggravating activities include cycling, walking and running on hills and repetitive step/stair activities.
The most common complaints are pain on the outside of the knee, over the upper thigh or over a bursa which lies on top of a bony protrusion called the Greater Trochanter. Pain can be burning, aching or a tightness feeling during or after exercise. Other complaints include redness, warmth and tenderness over the outside of the knee which may radiate to the front and tenderness over the buttocks.
So, what can you do? Immediately stop all aggravating activities. Apply ice to the painful area and rest the leg. See your physical therapist to determine the cause of the pain, treat the inflammation with modalities and exercises for stretching of tight structures and strengthening of weak muscles. As your rehab progresses you can return to your activities and sports pain free.
