In each of 73 patients with acute knee injuries, both menisci were examined by means of 7.5-MHz sector-scan sonography before arthroscopy was performed. In 87% of the cases the sonographic and arthroscopic diagnoses were identical. The results were better for the lateral meniscus. Overall, the sensitivity was 80% and the specificity, 90%. False-positive and false-negative results each accounted for 6%. In this series there was no correlation between the accuracy of the sonographic diagnosis and the type of meniscal lesion or its location within the meniscus.
在73例急性膝关节损伤患者中，于关节镜检查前，均采用7.5兆赫扇形扫描超声对双侧半月板进行检查。在87%的病例中，超声诊断与关节镜诊断结果一致。外侧半月板的诊断结果更佳。总体而言，敏感性为80%，特异性为90%。假阳性和假阴性结果各占6%。在该系列研究中，超声诊断的准确性与半月板损伤类型或其在半月板内的位置之间无相关性。
