The purpose of this study was to examine the relationship between osteochondritis dissecans (OCD) of the lateral femoral condyle and lateral menisci. From 1993 to 2002, 38 knees (28 patients) were diagnosed with OCD of the lateral femoral condyle. OCD locations were graded by the Cahill and Berg classification. The types of lateral menisci were classified by Watanabe's classification. The relationship between OCD of the lateral femoral condyle and lateral menisci was examined. On the anterior-posterior view, 25 OCDs were located in zone 4 and 13 in zone 5. The types of lateral menisci were complete discoid in 19 knees, incomplete discoid in 15, and normal in 4. Ten of the 19 complete discoid menisci were damaged. Complete discoid menisci without tears were found in OCDs located in zone 4; incomplete discoid menisci were found in OCDs located in zone 5. The authors found a relationship between the type of OCD and the state of the lateral meniscus.
本研究的目的是探讨外侧股骨髁剥脱性骨软骨炎（OCD）与外侧半月板之间的关系。1993年至2002年，38例膝关节（28例患者）被诊断为外侧股骨髁OCD。OCD的位置根据卡希尔和伯格分类法进行分级。外侧半月板的类型根据渡边分类法进行分类。研究外侧股骨髁OCD与外侧半月板之间的关系。在前后位片上，25个OCD位于4区，13个位于5区。外侧半月板的类型为完全盘状19例，不完全盘状15例，正常4例。19个完全盘状半月板中有10个受损。在位于4区的OCD中发现无撕裂的完全盘状半月板；在位于5区的OCD中发现不完全盘状半月板。作者发现OCD的类型与外侧半月板的状态之间存在关联。
