胫骨高位截骨术治疗老年膝关节内侧间室炎的疗效研究

Effects of high tibial osteotomy on medial compartmental knee osteoarthritis in elderly

目的 比较胫骨高位截骨术(high tibial osteotomy, HTO)治疗老年与非老年膝关节内侧间室炎的疗效。方法 回顾性分析26例接受HTO手术病人的临床资料,按照病人年龄分为≥60岁组(n=18)和<60岁组(n=8)。比较2组一般资料、手术截骨撑开角度及并发症发生情况,比较2组术前及术后1年VAS、膝关节功能评分量表(Knee Injury and Osteoarthritis Outcome Score, KOOS)各项评分。结果 2组性别、Kellgren-Lawrence(K-L)评级、BMI、手术截骨撑开角度、并发症发生率差异均无统计学意义(P>0.01)。2组术后1年VAS及KOOS各项评分均较术前明显改善(P<0.01)。术前及术后1年2组间VAS、KOOS各项评分差异均无统计学意义(P>0.01)。结论 HTO是一种安全且高效的膝关节内侧间室炎治疗手段,对于60岁及以上老年病人同样安全有效。

Objective To compare the efficacy of high tibial osteotomy(HTO)in treating medial compartment knee osteoarthritis in elderly and non-elderly patients.Methods The clinical data of 26 patients who underwent HTO surgery were retrospectively analyzed.The patients were divided into elderly group(aged≥60 years,n=18)and non-elderly group(aged<60 years,n=8).General information,surgical osteotomy angle and incidence of complications were compared between the two groups,and the scores of Visual Analogue Scale(VAS)and Knee Injury and Osteoarthritis Outcome Score(KOOS)in both groups were compared before and 1 year after surgery.Results There were no significant differences in sex,Kellgren-Lawrence(K-L)grade,body mass index(BMI),surgical osteotomy angle and incidence rates of complications between the two groups(P>0.01).There were also no significant differences in VAS and KOOS scores between the two groups before and 1 year after surgery(P>0.01),but the VAS score was significantly lower and the KOOS score was significantly higher in both groups after treatment than those before treatment(P<0.01).Conclusions HTO is safe and effective in treating medial compartment knee osteoarthritis in the elderly patients.
