Contributed by: Investigaciones Medicas, Radiologist, Investigaciones Medicas, Argentina.
History: Tenderness just up from the head of the fibula (the bone bump on the outer side of the knee, just around from the kneecap tendon. Pain occurs when the knee is fully straightened or fully bent, spread up the thigh or down the shin bone. This pain may be made worse by running on hills, running downhill, or climbing stairs.

Findings: MR images show partial disruption of the ileotibial tract, soft tissue edema, and maybe a bone bruise in the femoral condyle.
Discussion: : The ileotibial band is a long, wide tendon shaped structure, located on the outside of the leg. It starts near the hip joint, and runs along the outside of the leg. It then attaches to the tibia (shin bone) near the knee. Occasionally, this band of tissue becomes irritated and inflamed and causes pain: a condition known as ileotibial band syndrome. Is most common in sports that require repetitive bending of the knee. In particular, long distance runners and cyclists are particularly susceptible. Treatment: attack the cause, but back off the mileage and take anti-inflammatory drugs.
