Abstract：Objective:To observe the diagnostic value of high-frequency musculoskeletal ultrasound in chronic Achillestendon injury.Methods:204 patients underwent high-frequency musculoskeletal ultrasonography and conventional ultrasonography.from Sep.2020 to Sep.2022 in the hospital The diagnostic value of high-frequency musculoskeletal ultrasonography and conventional ultrasonography in chronic Achilles tendon injury was observed with surgical diagnosis as the gold standard.The accuracy difference in differential diagnosis of chronic Achilles tendon injury between high-frequency musculoskeletal ultrasonography and conventional ultrasonography was compared.Results:Among 204 patients with Achilles tendon injury,143 cases were diagnosed as chronic Achilles tendon injury and 61 cases as non-chronic Achilles tendon injury,including 24 cases of partial Achilles tendon rupture,35 cases of complete Achillestendon rupture,and 2 cases of healed Achilles tendon rupture.The sensitivity of high-frequency musculoskeletal ultrasound in the diagnosis of chronic Achillestendon injury was 93.71%,the specificity was 88.52%,the positive predictive value was 95.03%,the negative predictive value was 85.71%,the accuracy was 92.15%,and Kappa value was 0.815.The sensitivity,specificity,positive predictive value,negative predictive value,accuracy and Kappa value were 81.81%,73.77%,87.96%,63.38%,79.41%and 0.531 respectively in the diagnosis of chronic Achilles tendon injury by conventional ultrasound.The accuracy of conventional ultrasound in diagnosing chronic Achilles tendon injury was significantly lower than that of high-frequency musculoskeletal ultrasound,and the difference was statistically significant(P＜0.05).Conclusion:High-frequency musculoskeletal ultrasound has a high accuracy in the diagnosis of chronic Achilles tendon injury.It can effectively provide imaging information of Achillestendon.
