Abstract

OBJECTIVES

To quantify the improvement in health outcomes in patients after total knee replacement (TKR).

METHODS

This was a two-year non-randomized prospective observational study in knee osteoarthritis (OA) patients undergone TKR. Patients were interviewed one week before, six months after, and two years after surgery using a standardized questionnaire including the SF-36, the Oxford Knee Score (OKS), and the Knee Society Clinical Rating Scale (KSS). A generalized estimating equation (GEE) model was used to estimate the magnitudes of the changes with and without the adjustment of age, ethnicity, BMI, and years with OA.

RESULTS

A total of 298 (at baseline), 176 (at six-months), and 111 (at two-years) eligible patients were included in the analyses. All the scores changed significantly over time, with the exception of SF-36 social functioning, vitality, and mental health. With the adjustment of covariates, the magnitude of changes in these scores was similar to those without the adjustment.

CONCLUSIONS

Both general and knee-specific physical functioning had been significantly improved after TKR, while other health domains have not been substantially improved after the surgery.

摘要

目的

定量评估全膝关节置换术(TKR)后患者的健康结果改善情况。

方法

这是一项为期两年的非随机前瞻性观察性研究,纳入了膝关节骨关节炎(OA)患者接受 TKR 治疗。患者在术前一周、术后六个月和两年时使用标准化问卷进行访谈,问卷包括 SF-36、牛津膝关节评分(OKS)和膝关节学会临床评分量表(KSS)。采用广义估计方程(GEE)模型来估计调整年龄、种族、BMI 和 OA 患病年限前后变化的幅度。

结果

共纳入 298 名(基线时)、176 名(术后六个月时)和 111 名(术后两年时)符合条件的患者进行分析。所有评分均随时间显著变化,除 SF-36 社会功能、活力和心理健康外。调整协变量后,这些评分的变化幅度与未调整时相似。

结论

TKR 后,一般和膝关节特定的躯体功能显著改善,而手术后其他健康领域并未得到实质性改善。
