Abstract
Although arthrography is an important method for diagnosis of meniscus injuries, some techniques are needed for accurate reading of the resulting arthrograms. To find out what features of an arthrogram were easily misread with respect to differences between the medial and lateral menisci, and between types of tears, we compared preoperative arthrographic findings with intraoperative findings obtained from 54 patients undergoing surgery based on the diagnosis of meniscus injury alone. Arthrograms of 9 of the 54 patients were misread, or difficult to read. These 9 patients had either a torn surface with very complicated features (a bucket handle-like or longitudinal rupture) or a torn fragment displaced a relatively small amount (detachment of a marginal region of the meniscus) . Our findings suggest the importance of standardization of both arthrographic procedure and reading to achieve accurate roentgenographic diagnosis.
