We retrospectively reviewed the long-term results of total meniscectomy performed in seventeen knees (fourteen children) to treat a discoid lateral meniscus. The mean duration of follow-up was 19.8 years (range, 12.5 to 26.0 years). On the basis of the rating system of the International Knee Documentation Committee, seven knees were normal (grade A), six were nearly normal (grade B), three were abnormal (grade C), and one was severely abnormal (grade D) at the latest follow-up evaluation. Ten of the seventeen knees had clinical symptoms of osteoarthrosis. Radiographs were available for fifteen of the knees at the latest follow-up evaluation. Eleven of the treated knees could be compared with the uninvolved, contralateral knee. Ten knees had osteoarthrotic changes, such as flattening of the lateral femoral condyle, formation of a ridge along the lateral femoral condyle, and spurring and sclerosis of the tibial plateau. Osteochondritis dissecans developed in two knees, nine and twenty years after the initial meniscectomy.
我们回顾性地研究了为治疗盘状外侧半月板而对17个膝关节（14名儿童）进行全半月板切除术的长期结果。平均随访时间为19.8年（范围为12.5至26.0年）。根据国际膝关节文献委员会的评分系统，在最近的随访评估中，7个膝关节正常（A级），6个接近正常（B级），3个异常（C级），1个严重异常（D级）。17个膝关节中有10个出现骨关节炎的临床症状。在最近的随访评估中，15个膝关节有X线片可供分析。其中11个接受治疗的膝关节可与未受累的对侧膝关节进行比较。10个膝关节出现了骨关节炎改变，如外侧股骨髁变平、外侧股骨髁处形成骨嵴以及胫骨平台的骨刺和硬化。在初次半月板切除术后9年和20年，有2个膝关节发生了剥脱性骨软骨炎。
