An Anatomic Study of the Iliotibial Tract

The iliotibial tract can be considered as an anterolateral knee stabilizer, particularly its capsular-osseous layer, which, together with the anterior cruciate ligament, constitutes a functional unit forming a spatial "horseshoe" form. The detailed description of the structures forming iliotibial tract plays an important role in the study of knee instabilities. Its important tibial, femoral, and patellar connections are described so that better understanding of tibial femoral instability on the lateral side as well as patellofemoral instability can be achieved and mechanisms of repair can be conceived.
