Application of High-frequency Color Doppler Ultrasound in the Assessment of Knee Ligament Injury
摘要
Abstract
Objective To explore the application value of high-frequency color Doppler ultrasound in the assessment of knee ligament injury.Methods The clinical data of 152 patients with suspected knee ligament injury who were admitted to the 982nd Hospital of the Joint Logistics Support Force and received high-frequency color Doppler ultrasound examination from March 2023 to March 2025 were retrospectively analyzed.Taking arthroscopic surgery as the gold standard,the patients were divided into ligament injury group(knee ligament injury)(n=79)and non-ligament injury group(meniscal injury,articular cartilage injury)(n=73).The differences in ligament thickness,ligament cross-sectional area,synovial thickness and synovial blood flow grading between the two groups of patients at admission were compared.ROC curve was used to evaluate the diagnostic efficiency of the above-mentioned ultrasonic parameters for knee ligament injury.The patients in the ligament injury group were classified into mild-to-moderate group(≥65 points)(n=48)and severe group(<65 points)(n=31)according to the Lysholm Knee Scoring Scale.The differences in the above-mentioned ultrasonic parameters at admission in the two subgroups were analyzed.ROC curve was used to evaluate the assessment efficiency of the above-mentioned indicators on the severity of knee ligament injury.Results Among the 152 patients with suspected knee ligament injury who were examined in this study,123 patients underwent high-frequency color Doppler ultrasound and MRI.The Kappa value for consistency between high-frequency color Doppler ultrasound and arthroscopy was 0.707,and the Kappa value for consistency between MRI and arthroscopy was 0.837.At admission,the ligament thickness,ligament cross-sectional area and synovial thickness in the knee ligament injury group were significantly higher than those in the non-ligament injury group(P<0.05).There was a statistically significant difference in synovial blood flow grading between the ligament injury group and the non-ligament injury group(P<0.05).The proportion of grade 0 and grade I synovial blood flow in the ligament injury group was lower than that in the non-ligament injury group,while the proportion of grade Ⅱ and grade Ⅲ was higher.ROC curve results showed that the areas under the curves for diagnosing knee ligament injury based on ligament thickness,ligament cross-sectional area,synovial thickness and synovial blood flow grading were 0.823,0.829,0.789 and 0.752 respectively.At admission,the ligament thickness,ligament cross-sectional area and synovial thickness in the mild-to-moderate group were significantly lower than those in the severe group(P<0.05).there was a statistically significant difference in synovial blood flow grading between the mild-to-moderate group and the severe group(P<0.05).The proportion of grade 0 and grade Ⅰ synovial blood flow in the mild-to-moderate group was higher than that in the severe group,while the proportion of grade Ⅲ was lower.ROC curve results showed that the areas under the curves for assessing the severity of knee ligament injury based on ligament thickness,ligament cross-sectional area,synovial thickness,and synovial blood flow grading were 0.767,0.749,0.760 and 0.743 respectively.Conclusion High-frequency color Doppler ultrasound parameters have certain diagnostic efficiency on knee ligament injury and are helpful in determining the severity of knee ligament injury.关键词
