Ultrasound Imaging for the Evaluation of Anterior Talofibular Ligament Remnants in 547 Ankles With Chronic Lateral Ankle Instability

There are few reports on the intra- and interobserver agreement and parameters for the diagnostic accuracy of ultrasound (US) imaging for chronic lateral ankle instability (LAI). The purpose of this study was to investigate the reliability and validity of US imaging for identifying anterior talofibular ligament (ATFL) remnants in patients with LAI.
