Controversies exists about the value of sosgraphy in diagnosis of meniscal injuries. We therefore examined 179 knee joints. In a prospective study of 177 patients with knee problems, ultrasound was utilized to assess its values as a screening tool for meniscal tears. Prior to the arthroscopy the menisci were scanned from an independent team by using 7.5 and 10.0 MHz ultra-sound waves. 113 meniscal tears were seen at arthroscopy; 22% of these tears could not be detected by scanning (false negative results) while 10% of intact menisci showed positive echogenic structures analysed as meniscal tears. The results showed a sensitivity of 30.0% and a specificity of 85.3%. We cannot share the opinion of some autors that ultrasound is a reliable means of accurately diagnosing meniscal tears. It seems that ultrasound scanning of the menisci is still a experimental method without any clinical importance.
超声检查在半月板损伤诊断中的价值存在争议。因此，我们对179个膝关节进行了检查。在一项对177例膝关节问题患者的前瞻性研究中，超声被用作评估其作为半月板撕裂筛查工具的价值。在关节镜检查之前，由一个独立团队使用7.5和10.0兆赫的超声波对半月板进行扫描。在关节镜检查中发现113例半月板撕裂；其中22%的撕裂通过扫描无法检测到（假阴性结果），而10%的完整半月板显示出被分析为半月板撕裂的阳性回声结构。结果显示敏感性为30.0%，特异性为85.3%。我们不能认同一些作者的观点，即超声是准确诊断半月板撕裂的可靠手段。半月板的超声扫描似乎仍然是一种没有任何临床意义的实验方法。
