本研究的目的是记录1999年至2007年间19例接受膝关节外侧骨关节炎治疗的患者的中期随访结果。我们假设结果和并发症发生率与文献报道的闭合楔形或开放楔形技术相当或更好，所有患者均接受了开放楔形股骨远端内翻截骨术，使用Puddu钢板系统结合磷酸钙注射到缺损处。术前和末次随访时评估膝关节协会膝关节评分和Kelling-Lawrence骨关节炎评分，平均膝关节评分从术前43 +/-A8显著改善至末次随访时78 +/-A23。Kelling-Lawrence骨关节炎评分保持不变。Kaplan-Meier分析使用翻修手术或转为TKA作为终点，显示7年随访时成功存活率为82%。基于这些结果，我们认为，与闭合楔形技术相比，使用Puddu钢板和可注射骨水泥的股骨远端内翻截骨术是一种等效的治疗选择，并在中期随访时获得良好的结果-外侧膝关节病和外翻畸形的患者增加。
The goal of this study was to document the outcome at midterm follow-up of 19 patients treated for lateral osteoarthritis of the knee between 1999 and 2007. It was our hypothesis that the results and complication rate would be comparable to or better than those reported in the literature for closing wedge or alternative open wedge techniques.All patients underwent an open wedge distal femoral varisation osteotomy using the Puddu plate system combined with calcium phosphate injection into the defect. Knee Society Knee Score and Kellgren-Lawrence osteoarthritis score were assessed preoperatively and at final follow-up.The average knee score improved significantly from 43 +/- A 8 preoperatively to 78 +/- A 23 at final follow-up. The Kellgren-Lawrence osteoarthritis score remained unchanged. Kaplan-Meier analysis using revision surgery or conversion to TKA as an endpoint demonstrated an 82 % successful survivorship at 7 years of follow-up.Based upon these results, we believe that a distal femoral varisation osteotomy using the Puddu plate and injectable bone cement is an equivalent treatment option compared to closing wedge techniques and leading to good results at midterm follow-up in patients with lateral gonarthrosis and valgus alignment.IV.
