Abstract

INTRODUCTION

Unicompartmental knee arthroplasty (UKA) and valgus high tibial osteotomy (HTO) are two options for isolated medial femorotibial osteoarthritis in genu varum. In the absence of registries for osteotomies and for arthroplasty in the knee, epidemiological data are hard to obtain in France. We therefore performed a retrospective study, with the aims of: 1) estimating UKA and HTO survival without revision by total knee arthroplasty (TKA), and 2) assessing risk factors for revision according to treatment group.

HYPOTHESIS

Medium-term survival is better with HTO than UKA in under-70-year-olds.

MATERIALS AND METHOD

All elderly patients undergoing HTO or UKA in the French National Hospitals Database for the period 2011-2020 were included: i.e., 108,007 patients; 43,537 HTO (29,330 male, 14,207 female; mean age 49.7 years, 95% CI 49.6-49.8) and 64,470 UKA (31,181 male, 33,289 female; mean age 60.5 years, 95% CI 60.5-60.6).

RESULTS

Survival free of revision by TKA was 75.8% (95% CI=75.2-76.4) for UKA and 80.6% (95% CI=80.0-81.3) for HTO (p<0.00001). In UKA, revision risk factors comprised: low annual center volume (<17 UKAs per year) (HR=1.50; 95% CI=1.41-1.59), obesity (HR=1.25; 95% CI=1.18-1.32), and age <60years, with maximum risk for 50-59years (HR=2.41; 95% CI=1.83-3.16 in 50-59 year-olds). In HTO, revision risk factors comprised: obesity (HR=1.42; 95% CI=1.31-1.53), rheumatoid arthritis (HR=2.75; 95% CI=1.37-5.51), joint chondrocalcinosis (HR=2.01; 95% CI=1.18-3.39), and age >60years (HR=8.81; 95% CI=7.23-19.73 in 60-69-year-olds). Male gender was a protective factor against revision in both groups: UKA, HR=0.75 (95% CI=0.72-0.79); HTO, HR=0.73 (95% CI=0.69-0.77). The number of UKAs increased over the years, matching the increase in arthroplasty in France, with a decrease in HTOs until 2019.

CONCLUSION

HTO showed better medium-term survival than UKA in under-70-year-olds in France. Even so, indications decreased in favor of UKA, although the respective risk factors differ. These findings suggest that conservative surgery still has a role, depending on osteoarthritis stage.

摘要

简介

在膝内翻的孤立性内侧股胫关节炎患者中,单髁膝关节置换术(UKA)和外侧高位胫骨截骨术(HTO)是两种选择。由于法国没有关于截骨术和膝关节置换术的登记处,因此很难获得流行病学数据。因此,我们进行了一项回顾性研究,目的是:1)估计 UKA 和 HTO 不进行全膝关节置换术(TKA)翻修的生存率,2)根据治疗组评估翻修的风险因素。

假设

在 70 岁以下的患者中,HTO 的中期生存率优于 UKA。

材料和方法

纳入了 2011 年至 2020 年期间在法国国家医院数据库中接受 HTO 或 UKA 的所有老年患者:即 108007 名患者;43537 例 HTO(29330 名男性,14207 名女性;平均年龄 49.7 岁,95%置信区间 49.6-49.8)和 64470 例 UKA(31181 名男性,33289 名女性;平均年龄 60.5 岁,95%置信区间 60.5-60.6)。

结果

UKA 的 TKA 无翻修生存率为 75.8%(95%CI=75.2-76.4),HTO 为 80.6%(95%CI=80.0-81.3)(p<0.00001)。在 UKA 中,翻修的风险因素包括:年中心量低(<17 例 UKA/年)(HR=1.50;95%CI=1.41-1.59)、肥胖(HR=1.25;95%CI=1.18-1.32)和年龄<60 岁,其中 50-59 岁风险最大(HR=2.41;95%CI=1.83-3.16 岁)。在 HTO 中,翻修的风险因素包括:肥胖(HR=1.42;95%CI=1.31-1.53)、类风湿关节炎(HR=2.75;95%CI=1.37-5.51)、关节软骨钙质沉着症(HR=2.01;95%CI=1.18-3.39)和年龄>60 岁(HR=8.81;95%CI=7.23-19.73 岁)。在两组中,男性均为降低翻修风险的保护因素:UKA,HR=0.75(95%CI=0.72-0.79);HTO,HR=0.73(95%CI=0.69-0.77)。UKA 的数量逐年增加,与法国的关节置换术增加相匹配,而 HTO 则减少到 2019 年。

结论

在法国,70 岁以下的患者中,HTO 的中期生存率优于 UKA。尽管如此,尽管各自的风险因素不同,但 HTO 的适应证还是减少了,有利于 UKA。这些发现表明,根据骨关节炎的阶段,保守手术仍然有其作用。
