Illiotibial Friction Band Syndrome
Iliotibial friction band (ITB) syndrome typically causes pain at the outer (lateral) aspect of the knee where the (ITB) crosses the knee joint. The ITB is a long band of tissue that runs down the outer side of the leg and attaches below the knee. ITB friction syndrome describes a condition where the band rubs against a bony prominence at the outer aspect of the knee and causes inflammation and& pain. This condition is commonly seen in runners.
What are the symptoms of ITB friction syndrome?
Pain is usually experienced at the outer aspect of the knee. Patients usually experience an ache that may increase to a sharper pain with activity. The outer part of the knee may be tender to touch with potential swelling. In the morning or following activity (once the body has cooled down) is generally when pain is at its worst. Pain is also typically experienced during activities that bend or straighten the knee particularly whilst weight bearing, for example running, squatting or jumping.
How can physiotherapy help?
A physiotherapist will perform soft tissue massage to loosen the ITB in attempt to stop friction on the knee. They may use acupuncture or mobilisations to assist with pain and healing of the tissues. Mobilisation may also be used on the hip and knee to increase mobility at the joints with the aim to increase flexibility of the ITB. Stretching is important to return the ITB to its normal length and the use of a foam roller or gym equipment may be optimised. Strengthening exercises may also be provided to assist in reducing ITB symptoms and target the underlying cause such as biomechanical factors and posture, or muscle strength mismatching of the leg muscles. Further support such as taping may also be provided.
