AIMS
To evaluate the effect of waiting on health-related quality of life (HRQoL), pain and physical function in patients awaiting primary total knee replacement (TKR) due to osteoarthritis.
METHODS
Some 438 patients awaiting TKR were randomized to a short waiting time (WT) group (< or =3 months) or a non-fixed WT group. In the final assessment, 310 patients (213 women) with a mean age of 68 years were included. HRQoL was measured on being placed on the waiting list and again at hospital admission using the generic 15D. Patients' self-report pain and physical function were evaluated using a scale modified from the Knee Society Clinical Rating System.
RESULTS
The median WTs for patients with short and non-fixed WT were 73 days (range 8-600 days) and 266 days (range 28-818 days), respectively. At admission, as assessed by the intention-to-treat analysis, there were no statistically significant differences between the groups in the 15D total score and disease-specific pain and function.
CONCLUSIONS
Our study showed that longer WT did not result in worse pre-operative HRQoL.
目的
评估等待对因骨关节炎等待初次全膝关节置换术（TKR）患者的健康相关生活质量（HRQoL）、疼痛和身体功能的影响。
方法
约438名等待TKR的患者被随机分为短等待时间（WT）组（≤3个月）或非固定WT组。在最终评估中，纳入了310名平均年龄为68岁的患者（213名女性）。使用通用的15D量表在列入等待名单时和入院时测量HRQoL。使用从膝关节协会临床评分系统修改而来的量表评估患者的自我报告疼痛和身体功能。
结果
短WT组和非固定WT组患者的WT中位数分别为73天（范围8 - 600天）和266天（范围28 - 818天）。在入院时，通过意向性分析评估，两组在15D总分以及疾病特异性疼痛和功能方面无统计学显著差异。
结论
我们的研究表明，更长的WT并不会导致术前HRQoL更差。
