The anterolateral ligament and the deep structures of the iliotibial tract: MRI visibility in the paediatric patient

•Previous research only determined MRI visibility of the anterolateral ligament in adults and neglected the pediatric patient.•Previous studies only determined MRI visibility of the anterolateral ligament but not of the deep structures of the iliotibial tract.•The presence of the anterolateral structures of the knee can be determined by MRI in the pediatric population with substantial inter- and intraobserver agreement.•This holds for both the ALL and the deep structures of the ITT. To assess the visibility of both the anterolateral ligament (ALL) and the deep structures of the iliotibial tract (ITT) by means of MRI in paediatric patients. To determine reproducibility for such measurements. Knee MRI data from patients aged
