We report results of surgical treatment of ten knees affected by patellar dislocation in six children with Down syndrome. Four knees showed a dislocatable patella (grade III according to Dugdale), two a dislocated reducible patella (grade IV) and four a dislocated irreducible patella (grade V). Symptoms included frequent falls, limping and pain. In all the cases a Roux-Goldthwait-Campbell procedure was performed. Mean age at surgery was 10 years (range 6 years and 6 months to 13 years and 4 months). Patients were reviewed at an average follow-up of 8 years and 8 months (range 3 years and 6 months to 11 years and 5 months). None showed signs of recurrence of the dislocation. The median Lysholm score improved from 57.5 to 91/100. Statistical analysis showed a significant effectiveness of the procedure in improving function, and that surgery was significantly more effective in patients with more severe disability.
我们报告了对6名患有唐氏综合征的儿童中10个受髌骨脱位影响的膝关节进行手术治疗的结果。4个膝关节显示髌骨可脱位（根据Dugdale分级为III级），2个为脱位可复位髌骨（IV级），4个为脱位不可复位髌骨（V级）。症状包括频繁跌倒、跛行和疼痛。所有病例均采用Roux-Goldthwait-Campbell手术。手术时的平均年龄为10岁（范围为6岁6个月至13岁4个月）。患者平均随访8年8个月（范围为3年6个月至11年5个月）。均未显示脱位复发迹象。Lysholm评分中位数从57.5提高到91/100。统计分析表明该手术在改善功能方面具有显著疗效，且手术对残疾程度较重的患者疗效显著更佳。
