    BackgroundAnterior talofibular ligament (ATFL) injury is a commonly seen sports-related injury and a major underlying pathology of chronic ankle instability. However, it is difficult to accurately identify chronic injury of the ATFL.PurposeTo investigate the value of ultrasound (US) examination in identifying chronic ATFL injury.Material And MethodsWe evaluated 83 consecutive patients who underwent US examination for diagnosis of the ATFL injury and subsequent ankle arthroscopy. The arthroscopic findings were used as the reference standard.ResultsForty-four patients were found to have ATFL injury on arthroscopy. The accuracy of US examination for the detection of ATFL injury was 95.2%, with sensitivity of 97.7%, specificity of 92.3%, positive predictive value of 93.5%, negative predictive value of 97.3%, positive likelihood ratio of 12.7, and negative likelihood ratio of 0.025.ConclusionUS examination is a reliable and accurate method to evaluate chronic ATFL injury.
