Osteochondritis dissecans (OCD) of the lateral femoral condyle sometimes occurs with a discoid lateral meniscus. Recently, it was reported that OCD of the lateral femoral condyle occurred after total removal of the lateral meniscus. We report the case of a 12-year-old boy with bilateral OCD of the lateral femoral condyle following bilateral total removal for discoid lateral meniscus. Valgus deviation of the knee after total removal and increased sporting activity might have concentrated excessive stress on the lateral condyles in the standing position. As a result, bilateral OCD might have occurred. Drilling of the areas of OCD on the bilateral lateral femoral condyles was done and the patient wore inner wedge arch supports postoperatively. After 2 years, neither knee pain nor arthrosis has occurred so far, but long-term follow-up of this patient is considered to be necessary.
外侧股骨髁剥脱性骨软骨炎（OCD）有时与外侧盘状半月板同时出现。最近，有报道称在外侧半月板完全切除后发生了外侧股骨髁OCD。我们报告了一例12岁男孩，因双侧外侧盘状半月板完全切除后出现双侧外侧股骨髁OCD。完全切除后膝关节外翻畸形以及体育活动增加可能使站立位时外侧髁承受了过多压力。结果，双侧发生了OCD。对双侧外侧股骨髁的OCD区域进行了钻孔，术后患者佩戴内侧楔形足弓支撑。2年后，到目前为止，双膝均未出现疼痛或关节病，但认为对该患者进行长期随访是必要的。
