Iliotibial Band Syndrome (Knee)

Introduction

The iliotibial band is a thick band of fascia (fibrous tissue) that begins at the lateral aspect of the hip and crosses the knee joint at the outside of the knee. When this tendon becomes inflamed, it is known as Iliotibial Band Syndrome. 

Iliotibial Band Syndrome is a common injury, particularly in athletes, and most commonly sustained as a result of overuse. As athletes run or do other strenuous activities involving their legs, the iliotibial band can rub up against the bone and become inflamed. Patients typically experience pain at the outside of the knee. To diagnose this condition, a physician will perform an examination and may order X-rays. Rarely, an MRI is ordered to view the condition of the ligament.
