Abstract
- Double contrast arthrography of the knee is a highly accurate diagnositc modality in wide rage of the clinical disorders of the knee. It allows radiological assessment of the menisci, the articular cartilages, the synovium and the ligaments. The double contrast knee arthrography was performed in 365 cases at Inha hospital for about 3 years from June 1989. Among them, 115 cases were abnormal, and were analyzed clinically and radiologically withthe back graound of the operative finding. The results were as follows: 1. Of the 115 cases, male were 77 and female 38. Male exceeds female in the ratio of 2:1. 2. The age group of 10-39 years was commonly involved(60%). 3. The right knee was more commonly involved than the left and the medial meniscus tear was more common (61%). The posterior horn of the meniscus was more frequently torn than the other parts of the meniscus(42%). 4. Theincidenced of the bucket-handle tear was the most frequent(33%). 5. The cases of the popliteal cyst were16(13.9%), and the combined meniscus tears were in 4 cases(25%). 6. The number of the discoid menisci were9(7.8%), and all were present in the lateral meniscus, and combined tears were in 4 cases(44.4%). 7. The diagnostic accuracy of the double contrast knee arthrogram was 82.7% compared with operative finding. The falsepositive examination were 17.3%.
