This paper shows the results of using air as a contrast medium in ultrasonography of the menisci (aerosonography). 100 menisci (50 knees) were examined with aerosonography and in 93 = 93% the findings were proven to be true by subsequent arthroscopy. 6% of the findings were false positive (2 medial menisci and 4 lateral menisci). One false negative finding concerned a lesion at the free inner edge of the lateral meniscus. Not one single lesion of the medial meniscus was totally missed. The sensitivity of aerosonography is 97.8%, the specificity 89.1%. The predictive value is 88%, the accuracy is 93%. Considering the medial meniscus alone the aerosonographic diagnosis proved to be true in 96% (sensitivity for the medial meniscus 100%, specificity 87.5%, predictive value 94.4%, accuracy 96%). 90% of the aerosonographic diagnosis concerning the lateral meniscus were confirmed by arthroscopy (sensitivity for the lateral meniscus 90.9%, specificity 89.1%, predictive value 71.4%, accuracy 90%).
本文展示了在半月板超声检查中使用空气作为对比介质（空气超声检查）的结果。对100个半月板（50个膝关节）进行了空气超声检查，其中93个（93%）的检查结果在随后的关节镜检查中被证实为真。6%的检查结果为假阳性（2个内侧半月板和4个外侧半月板）。1例假阴性结果涉及外侧半月板游离内缘的一处损伤。内侧半月板的任何一处损伤均未被完全漏诊。空气超声检查的敏感性为97.8%，特异性为89.1%。预测值为88%，准确性为93%。仅考虑内侧半月板时，空气超声诊断被证实为真的比例为96%（内侧半月板的敏感性为100%，特异性为87.5%，预测值为94.4%，准确性为96%）。关节镜检查证实了90%的关于外侧半月板的空气超声诊断（外侧半月板的敏感性为90.9%，特异性为89.1%，预测值为71.4%，准确性为90%）。
