Definition
On the lateral aspect of the thigh, the tensor fasciae latae is a flat, band-shaped tendon. It extends from the upper femur to the upper tibia (Gerdy's tubercle).
During walking, it moves back and forth like a windshield wiper. It then passes over the lateral femoral condyle.
Under certain conditions, the fascia lata "catches" as it passes over the femoral condyle. This repeated conflict causes painful irritation. The resulting discomfort is called iliotibial band syndrome, or "windshield wiper syndrome," or iliotibial band friction syndrome. It affects certain sports such as running, cycling, and downhill mountain hiking.
Clinical features
Pain located in the lateral compartment of the knee, sometimes radiating along the lateral aspect of the thigh. It occurs with exertion and develops progressively.
MRI
T2 hyperintensity at the TFL-lateral condyle interface.
Possible remodeling of the iliotibial band with thickening, or even intratendinous fissuring
