Injuries of the knee often present diagnostic problem. Using double contrast arthrography, each segment of the two menisci can be studied in detail. In addition, ligamentous tears can be detected. This method is particularly useful when the clinical signs are non-specific and the symptoms atypical. In the present series, double contrast arthrography was performed in 100 cases of suspected internal derangement of the knee. Abnormal radiological findings were recorded in 31 cases. Confirmation of the diagnosis was available in 17 out of 21 patients, subjected to surgery, giving a pre-operative diagnostic accuracy of 81%. This figure could be improved with experience and can be further enhanced, if used in conjunction with arthroscopy.
膝关节损伤常常带来诊断难题。运用双重对比关节造影术，两个半月板的每个部分都能得到详细研究。此外，还能检测出韧带撕裂。当临床体征不具特异性且症状不典型时，这种方法特别有用。在本系列研究中，对100例疑似膝关节内部紊乱的病例进行了双重对比关节造影术。31例有异常放射学表现。在接受手术的21例患者中，17例确诊，术前诊断准确率为81%。随着经验的积累，这个数字会得到改善，若与关节镜检查结合使用，准确率还能进一步提高。
