Abstract：Objective To compare the value of high-frequency ultrasound and MRI in the diagnosis of anterior talofibular ligament(ATFL)injury and early detection of chronic ankle instability(CAI).Methods Eighty patients with unilateral ankle injuries who receive treatment at Gansu Provincial People's Hospital from January 2020 to August 2024 were selected.All patients underwent both high-frequency ultrasound and MRI,with injury severity classified into three grades.The thickness and length of the ATFL,as well as the angle of the talofibular joint space,were measured and compared between the healthy and affected sides.Surgical outcomes were used as the gold standard,and ROC curves for ATFL injury diagnosis by both high-frequency ultrasound and MRI were plotted to evaluate diagnostic efficacy.Results Among the 80 patients,high-frequency ultrasound detected 13 cases of grade I,39 cases of grade II,and 28 cases of grade III injuries,while MRI detected 24 cases of grade I,42 cases of grade II,and 14 cases of grade III.The detection rate of grade I injury by high-frequency ultrasound was significantly lower than MRI,with grade II detection slightly lower and grade III detection significantly higher than MRI(P<0.001).Conclusion The thickness of the affected ATFL was positively correlated with injury grade.The angle of the affected ATFL relative to the talofibular joint space and its length were positively correlated with the diagnostic concordance rate for chronic ankle instability.Combining multiple ultrasonographic parameters proved more valuable for diagnosing chronic ankle instability,providing an objective basis for surgical repair of ligament injuries.
