Iliotibial (IT) Band Syndrome
That nagging pain on the outer thigh and knee in runners and cyclists, what IT band syndrome is, who's at risk, and how to treat it.
The iliotibial (IT) band is the tendon or band that stretches from the hip or pelvic bone to the knee. When it becomes irritated or inflamed, it causes swelling and pain on the outer thigh and the outside of the knee.
People at higher risk include athletes like long-distance runners, cyclists, and basketball and soccer players, as well as people with arthritis and weakness of the hip and buttock muscles. Women are more prone to IT band syndrome, and running downhill can worsen the knee or hip and thigh pain.
Diagnosis is often made with a physical exam that reveals tenderness of the IT band on palpation or with walking. Ultrasound can be useful, and MRI can help exclude other problems. It's also important to rule out other causes of hip and knee pain.
Treatment may include rest, ice, heat, physical therapy, and using a foam roller, and sometimes steroid injections. One practical tip: change your sneakers every few months, worn-out shoes can keep the problem going.
