Abstract: ［Abstract］ Objective To compare the efficacy of anatomical locking plate and conventional plate fixation in high tibial osteotomy for the treatment of knee osteoarthritis. Methods The clinical data of 34 patients with knee osteoarthritis admitted to Shenzhen Bao′an People′s Hospital from January 2013 to December 2018 were retrospectively analyzed. According to the fixation methods， the patients were divided into anatomical locking plate group and conventional plate group. The operation time， intraoperative bleeding volume， fracture healing time， Lysholm score of knee joint function at 3 months， 6 months and 1 year after operation， and the incidence of complications were compared between the two groups. Results There was no significant difference in bleeding volume between two groups （P>0.05）|the fracture healing time of the anatomical locking plate group was lower than that of the conventional plate group （P=0.000）|the operation time was longer inanatomical locking plate groupthan that of conventional plate group （P=0.002）. Lysholm score was higher in the anatomical locking plate group in three months，6 months and one year after operation （P<0.05）. The incidence of complications was 5.0% in the anatomical locking plate group and 35.7% in the conventional plate group. There was significant difference between the two groups （P=0.021）. Conclusion Anatomical locking platewith high tibial osteotomy could achieve satisfactory results in the treatment of knee osteoarthritis.

摘要： ［摘要］ 目的 比较解剖锁定钢板内固定和普通钢板内固定在胫骨高位截骨治疗膝关节骨关节炎中的疗效。方法 回顾性地分析深圳市宝安人民医院（集团）2013年1月1日至2018年12月31日期间收治的共34例膝内侧骨关节炎患者相关的临床病例资料。然后根据内固定方法的不同分为解剖锁定钢板内固定组和普通钢板内固定组。比较两组膝内侧骨关节炎患者之间的手术时间、术中出血量、骨折愈合时间，术后3个月、半年及1年膝关节功能的Lysholm评分，以及术后并发症的发生情况。结果 经过统计分析发现，解剖锁定钢板内固定组与普通钢板内固定组比较，术中出血量的差异无统计学意义（P>0.05）、骨折愈合时间较短（P=0.000）、手术时间长于普通钢板内固定组（P=0.002）。与普通钢板内固定组比较，解剖锁定钢板内固定组术后3个月、术后半年、术后1年膝关节功能的Lysholm评分较高（P<0.05）。解剖锁定钢板内固定组术后并发症发生比例为5.0%；普通钢板内固定组术后并发症发生比例为35.7%，差异有统计学意义（P=0.021）。结论 解剖锁定钢板内固定在胫骨高位截骨治疗膝关节骨关节炎中可获得满意的疗效，骨折愈合时间短，并发症较少。
