The iliotibial band runs from the lateral pelvis to the outside of the knee, attaching to the tibia. The iliotibial band stabilizes the knee and hip during walking, standing and running. Iliotibial band tendinitis is also known as Iliotibial Band Friction Syndrome. This condition is caused when a bursa below the iliotibial band that helps the band glide over the lateral femoral condyle of the femur becomes irritated. When this bursa is inflamed or swollen the iliotibial band does not glide smoothly and develops into Iliotibial band tendinitis.
