背景资料：很少有研究评价了胫骨高位外翻截骨术（HTO）后长期随访中年龄对患者报告结局的影响。本研究的目的是评估手术年龄与HTO中长期随访中患者报告的临床结局之间的相关性。材料和方法：我们将2011年膝关节协会评分（KSS）问卷邮寄给234名连续患者（295例膝关节）接受了闭合楔形HTO，158例患者（202例膝关节，68.5%）返回了完整的问卷。根据手术时的年龄将队列分为两组，并配对随访期和性别。平均随访期约为12年。采用t检验和卡方检验比较两组患者在最后随访时的KSS评分，并采用Kaplane-Meier生存曲线计算生存率。结果：65岁以上患者的症状、满意度和期望评分无显著性差异。老年患者的功能活动评分明显低于年轻患者。HTO的5年总生存率为99.1 +/- 0.4%，10年为94.4 +/- 1.2%，15年为84.6 +/- 2.7%。HTO后的生存率按年龄划分的两组之间没有显着差异（p = 0.602）。结论：HTO后，在老年患者的疼痛缓解和满意度是可比的年轻患者在中期至长期随访，虽然功能活动受年龄。(C)2019年日本骨科协会。Elsevier B.

Background: Few studies have evaluated the impact of age on patient-reported outcomes in the long-term follow-up after high tibial valgus osteotomy (HTO). The purpose of this study is to assess the association between age at surgery and patient-reported clinical outcomes in the mid-term to long-term follow-up of HTO.Materials and methods: We mailed the 2011 Knee Society score (KSS) questionnaires to 234 consecutive patients (295 knees) who had undergone closing-wedge HTO, and 158 patients (202 knees, 68.5%) returned a completed questionnaire. The cohort was divided into two groups depending on the age at the time of surgery, and pairs matched the follow-up period and sex was created. The mean follow-up period was approximately 12 years. KSS scores at the final follow-up were compared between two groups using the Student t test and chi-square test, and the survival rates were calculated using Kaplane-Meier survival curves.Results: The symptom, satisfaction, and expectation scores were not significantly different between the = 65-year-old patients. The functional activities score was significantly lower in older patients than in younger patients. The overall survival rates of HTO were 99.1 +/- 0.4% at 5 years, 94.4 +/- 1.2% at 10 years, and 84.6 +/- 2.7% at 15 years. There was no significant difference in the survival rate after HTO between the two groups divided by the age (p = 0.602).Conclusions: Pain relief and satisfaction after HTO in older patients were comparable to those in younger patients in the mid-term to long-term follow-up, although the functional activity was affected by age.
