RUNNER’S KNEE
ILIOTIBIAL BAND FRICTION SYNDROME
ANATOMY
The Iliotibial band (ITB) is a fibrous band that is continuous with the tendons of the gluteus maximus and tensor of fascia latae muscles of the buttock. It runs down the lateral aspect of the thigh, connecting to the lateral condyle of the tibia.
MECHANISM OF INJURY
During stages of knee flexion/extension in running the ITB flicks over the lateral femoral condyle. Muscle tightness and other factors can exaggerate this flicking, causing irritation of the ITB.
SYMPTOMS
- Pain localized to the lateral side of the knee may limit activity. It may radiate proximally or distally. After resting the pain may disappear, but it recurs if running is resumed.
- Running downhill or climbing stairs may aggravate the symptoms, as these activities cause excessive friction of the iliotibial band on the lateral condyle.
- Localized tenderness on the lateral condyle is felt approximately 3cm proximal to the lateral joint line.
TREATMENT
Please consult with your medical professional for a complete diagnosis and treatment plan.
