There is no consensus regarding the clinical significance of conventional two-dimensional ultrasound in the diagnosis of meniscal tears of the knee. Three-dimensional ultrasound spatially reconstructs a transparent image of subsequent ultrasound scans. In an experimental study of 96 menisci, radial and oblique tears were detected more often by three-dimensional ultrasound. In a clinical study of 60 menisci the two- and three-dimensional ultrasound reached a sensitivity of 92% and 100%, a specificity of 83% and 88%, a positive predictive value of 58% and 67%, and a negative predictive value of 98% and 100%, respectively. Altogether, there was no statistically significant difference between both methods. The high negative predictive value, however, shows that the three-dimensional ultrasound may be a clinically relevant examination for special questions in the diagnostics of meniscal tears.
关于传统二维超声在诊断膝关节半月板撕裂中的临床意义，目前尚无共识。三维超声可对后续超声扫描进行空间重建，生成透明图像。在一项对96个半月板的实验研究中，三维超声检测到的放射状和斜形撕裂更为常见。在一项对60个半月板的临床研究中，二维和三维超声的灵敏度分别为92%和100%，特异度分别为83%和88%，阳性预测值分别为58%和67%，阴性预测值分别为98%和100%。总体而言，两种方法之间无统计学显著差异。然而，高阴性预测值表明，三维超声可能是一种针对半月板撕裂诊断中特殊问题的具有临床相关性的检查方法。
