Abstract：Objective To investigate the value of high-frequency musculoskeletal ultrasound imaging in the diagnosis of lateral collateral ligament injuries of the ankle joint.Methods A total of 79 patients with lateral collateral ligament injuries of the ankle joint admitted to the General Hospital of Northern Theater Command of PLA from July 2020 to July 2024 were enrolled.Using MRI and surgical results as the gold standard,musculoskeletal ultrasound imaging was performed before surgery to evaluate the accuracy and compare the diagnostic efficacy.Results The accuracy rate of high-frequency musculoskeletal ultrasound imaging in diagnosing lateral collateral ligament injuries of the ankle joint was 97.47％.The sensitivity for type Ⅲ ligament injuries was 90.9％,which was higher than that for type Ⅰ and type Ⅱ injuries.The diagnostic rates of high-frequency musculoskeletal ultrasound imaging for injuries in different sites(calcaneofibular ligament,anterior talofibular ligament,and posterior talofibular ligament)were 90％,100％,and 100％,respectively,with no statistically significant differences among them(P＞0.05).There were no significant differences in accuracy,sensitivity,and missed diagnosis rate between high-frequency musculoskeletal ultrasound imaging and magnetic resonance examination or surgical exploration(P＞0.05).Conclusion High-frequency musculoskeletal ultrasound imaging can dynamically observe the lateral collateral ligament of the ankle joint,clearly display the type and degree of ligament injury,and reflect the differences in various diagnostic efficacy indicators among different ligament types.It provides an effective basis for early targeted clinical treatment and the prompt recovery of patients.
