Osteochondritis dissecans (OD) is a rare occurrence. In the knee, the most common localization is the lateral region of the internal femoral condyle. Involvement of the external condyle only occurs in 15% of cases, but its features are such that the situation is an entity in itself. The lesion is generally localized in the posterior site, and it is more extensive and more symptomatic as compared to medial localizations; moreover, early and rapid arthritic progression is observed. Reported here are 2 cases of OD of the lateral femoral condyle with atypical features in terms of clinical findings and progression of the disease as compared to more frequently occurring medial localizations.
剥脱性骨软骨炎（OD）较为罕见。在膝关节中，最常见的发病部位是股骨内侧髁的外侧区域。外侧髁受累仅发生于15%的病例中，但其特征表明这本身是一种独立的情况。该病变通常位于后方部位，与内侧发病部位相比，范围更广且症状更明显；此外，还观察到关节炎早期快速进展。本文报告了2例股骨外侧髁剥脱性骨软骨炎病例，与更常见的内侧发病部位相比，其临床表现和疾病进展具有非典型特征。
