Osteochondritis dissecans (OD) of the lateral tibial condyle is a rare condition. A review of the literature revealed only nine cases in seven patients. We report about a new case. It is widely accepted that this form of OD originates from an accessory center of ossification. Our case supports this theory. Although comparative roentgenograms of the left knee, taken because of complaints in the right one, were interpreted to be normal, retrospective analysis clearly revealed the lateral intercondylar eminence of the left knee to have been irregular many years before the onset of symptoms. Association with a classical OD in the contralateral knee is striking in most of the reported cases.
外侧胫骨髁剥脱性骨软骨炎（OD）是一种罕见的病症。文献回顾显示，仅7例患者中有9例。我们报告一例新病例。人们普遍认为，这种形式的OD起源于一个副骨化中心。我们的病例支持这一理论。尽管因右膝不适拍摄的左膝对比X线片被解读为正常，但回顾性分析清楚地显示，在症状出现多年前，左膝的外侧髁间隆起就已不规则。在大多数报告的病例中，与对侧膝关节的典型OD相关联的情况很显著。
