Abstract

Background: Quality of life in patients receiving knee arthroplasty is crucial for rehabilitation. Even if the validity of the 36-Item Short Form (SF-36) was already confirmed, the Substantial Clinical Benefit (SCB) and Patient Acceptable Symptom Score (PASS) values of this score remain unknown for both Total Knee Arthroplasty (TKA) and Unicompartmental Knee Arthroplasty (UKA).

Objective: The purpose of this research was to compute the Minimal Clinically Important Difference (MCID) of the SF-36 after UKA, and the SCB and PASS of SF-36 after TKA and UKA, in order to assess post-surgery quality of life in knee osteoarthritis.

Methods: Overall, 59 patients (40 women and 19 men, mean age 60.3 ± 13.1 years) completed the questionnaire until six months follow-up. Of these patients, 22 underwent the TKA procedure, while 37 patients underwent the UKA procedure. The anchor question for computing the MCID and SCB thresholds was "How would you describe your health condition in relation to your previous state?". The PASS scores were determined using the ROC curve and the 75th percentile of the cumulative percentage curve of respondents who believe their symptoms are under control.

Results: The MCID values of global SF-36, Physical Component Summary (PCS) and Mental Component Summary (MCS) after UKA were 11.3, 14.5 and 11.4, respectively. The SCB values of global SF-36, PCS and MCS after UKA were 23.5, 23.1 and 15, respectively. The PASS values of global SF-36, PCS and MCS after TKA were 71.2, 75 and 69.3, respectively. The PASS values of global SF-36, PCS and MCS after UKA were 70.4, 72.1 and 67.5, respectively.

Conclusion: The SF-36 score represents a valid score for quality of life in patients with knee osteoarthritis. Taken together, the results showed a statistically significant improvement between inception and latest follow-up after TKA and UKA.

评估膝关节骨关节炎术后生活质量的36项简短健康调查（SF-36）的最小临床重要差异

背景：膝关节置换术患者的生活质量对康复至关重要。即使36项短表（SF-36）的有效性已经得到证实，对于全膝关节置换术（TKA）和单室膝关节置换术（UKA），该评分的实际临床获益（SCB）和患者可接受症状评分（PASS）值仍然未知。目的：本研究的目的是计算膝关节骨关节炎术后SF-36的最小临床重要差异（minimum clinical Important Difference， MCID），以及TKA和UKA后SF-36的SCB和PASS，以评估膝关节骨关节炎术后生活质量。方法：59例患者（女性40例，男性19例，平均年龄60.3±13.1岁）完成问卷调查，随访6个月。在这些患者中，22例接受了TKA手术，37例接受了UKA手术。计算MCID和SCB阈值的锚定问题是“你如何描述你的健康状况与你以前的状态？”通过使用ROC曲线和认为其症状得到控制的应答者累积百分比曲线的第75百分位来确定PASS分数。结果：UKA后整体SF-36、Physical Component Summary （PCS）和Mental Component Summary （MCS）的mcd值分别为11.3、14.5和11.4。UKA后全球SF-36、PCS和MCS的SCB值分别为23.5、23.1和15。TKA后SF-36、PCS和MCS的PASS值分别为71.2、75和69.3。UKA后全球SF-36、PCS和MCS的PASS值分别为70.4、72.1和67.5。结论：SF-36评分是衡量膝骨关节炎患者生活质量的有效评分。综上所述，结果显示在TKA和UKA后的开始和最新随访期间有统计学上显著的改善。

期刊介绍： The Journal of Back and Musculoskeletal Rehabilitation is a journal whose main focus is to present relevant information about the interdisciplinary approach to musculoskeletal rehabilitation for clinicians who treat patients with back and musculoskeletal pain complaints. It will provide readers with both 1) a general fund of knowledge on the assessment and management of specific problems and 2) new information considered to be state-of-the-art in the field. The intended audience is multidisciplinary as well as multi-specialty. In each issue clinicians can find information which they can use in their patient setting the very next day.
