Abstract

Aims

To assess functional outcomes, health-related quality-of-life (HRQoL), and satisfaction at 1-year following knee arthroplasty (KA) in patients aged ≥80 compared to those aged 65–75-years when adjusting for confounding factors.

Methods

A single-centre retrospective cohort study was performed using data from 2010 to 2020. Demographic data, length of stay (LOS), preoperative and 1-year postoperative EuroQol (EQ-5D and EQ-VAS), Oxford Knee Score (OKS) and Outcome Satisfaction (OS) were recorded. Patients aged ≥80 were compared to a control group aged 65–75-years. Regression analyses were performed to assess the independent association of age group after adjusting for confounding factors.

Results

Compared to the 65–75-year group (n = 7525) the ≥80-year group (n = 2966) had greater comorbidity (p < 0.001), worse preoperative OKS (p < 0.001) and EQ-VAS (p = 0.012). Postoperatively both groups had clinically and statistically significant (p < 0.001) improvements in OKS, EQ-5D and EQ-VAS. There was no difference in improvement in OKS (mean difference (p = 0.081) or OS (p = 0.203) between the groups. However, the ≥80-year group had less of an improvement in EQ-5D (p = 0.047) and EQ-VAS (p = 0.007), but these were not clinically meaningful. However, when adjusting for confounding variables there were no differences in improvement in OKS (p = 0.372), EQ-5D (p = 0.703), and EQ-VAS (p = 0.283), or OS (p = 0.829) between the groups. The ≥80-year group was independently associated with a longer LOS (95% CI 0.3–0.8, p < 0.001) when adjusting for confounding factors.

Conclusions

Patients ≥80-years had clinically significant improvements in joint-specific outcome and HRQoL and OS equal to those aged 65–75-years following KA. The ≥80 group had a longer mean LOS of half a day.

与65-75岁接受膝关节置换术的患者相比，80岁及以上的患者在关节特异性结局、健康相关的生活质量和满意度方面有同等的改善

目的评估膝关节置换术（KA）后 1 年的功能结果、健康相关生活质量（HRQoL）和满意度，并与 65-75 岁的患者进行比较，同时对混杂因素进行调整。研究记录了人口统计学数据、住院时间（LOS）、术前和术后1年的EuroQol（EQ-5D和EQ-VAS）、牛津膝关节评分（OKS）和结果满意度（OS）。年龄≥80岁的患者与65-75岁的对照组进行了比较。结果与 65-75 岁组（n = 7525）相比，≥80 岁组（n = 2966）的合并症较多（p < 0.001），术前 OKS（p < 0.001）和 EQ-VAS （p = 0.012）较差。术后，两组患者的 OKS、EQ-5D 和 EQ-VAS 均有临床和统计意义上的显著改善（p < 0.001）。两组在 OKS（平均差异（p = 0.081）或 OS（p = 0.203）方面的改善没有差异。然而，≥80 岁组在 EQ-5D（p = 0.047）和 EQ-VAS （p = 0.007）方面的改善较小，但这些改善并无临床意义。然而，在对混杂变量进行调整后，各组之间在 OKS（p = 0.372）、EQ-5D（p = 0.703）和 EQ-VAS （p = 0.283）或 OS（p = 0.829）的改善方面没有差异。结论与 65-75 岁的患者相比，≥80 岁的患者在接受 KA 治疗后，关节特异性结果、HRQoL 和 OS 均有显著的临床改善。≥80岁组患者的平均住院日延长了半天。

期刊介绍： The Knee is an international journal publishing studies on the clinical treatment and fundamental biomechanical characteristics of this joint. The aim of the journal is to provide a vehicle relevant to surgeons, biomedical engineers, imaging specialists, materials scientists, rehabilitation personnel and all those with an interest in the knee. The topics covered include, but are not limited to: • Anatomy, physiology, morphology and biochemistry; • Biomechanical studies; • Advances in the development of prosthetic, orthotic and augmentation devices; • Imaging and diagnostic techniques; • Pathology; • Trauma; • Surgery; • Rehabilitation.
