Meniscal tears are a common cause of knee pain and disability. The objective measurement of the health-related quality of life of patients with meniscal tears plays a key role in clinical evaluation and therapeutic decision making. Several evaluation tools have been used to measure the effects of meniscal tears on knee function and quality of life. However, most of these tools are nonspecific for meniscal pathology.
PURPOSE/HYPOTHESIS: The purpose of the present study was to compare the capability of 3 commonly used knee assessment tools to measure the impact of meniscal tears on knee function and quality of life: the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the Knee injury and Osteoarthritis Outcome Score (KOOS), and the Western Ontario Meniscal Evaluation Tool (WOMET). Our null hypothesis was that no difference would exist among the 3 assessment tools.
Cohort study (diagnosis); Level of evidence, 2.
A total of 207 consecutive patients (mean ± SD: age, 52.6 ± 14.3 years) with arthroscopically confirmed meniscal tear were included. Preoperatively, 3 knee function and quality-of-life scores were obtained: KOOS, WOMAC, and WOMET. The relative outcome scores of the questionnaires were compared postoperatively.
The sum scores (relative scores) were as follows: 234.2 ± 92.5 (55.7%) for the KOOS, 132.6 ± 54.3 (55.5%) for the WOMAC, and 113 ± 30.8 (71%) for the WOMET. The relative score results for the WOMET were significantly higher than those for the WOMAC and the KOOS (both < .01), while no significant difference was found between the WOMAC and the KOOS ( = .735).
A greater impact on health-related quality of life for patients with meniscal tears can be measured with the WOMET when compared with the WOMAC and the KOOS. Therefore, using the WOMET can be recommended for the evaluation of knee function and quality-of-life impairment of patients with meniscal tears.
半月板撕裂是膝关节疼痛和功能障碍的常见原因。对半月板撕裂患者与健康相关的生活质量进行客观测量在临床评估和治疗决策中起着关键作用。已有多种评估工具用于测量半月板撕裂对膝关节功能和生活质量的影响。然而，这些工具大多对半月板病变缺乏特异性。
目的/假设：本研究的目的是比较3种常用的膝关节评估工具测量半月板撕裂对膝关节功能和生活质量影响的能力：西安大略和麦克马斯特大学骨关节炎指数（WOMAC）、膝关节损伤和骨关节炎疗效评分（KOOS）以及西安大略半月板评估工具（WOMET）。我们的零假设是这3种评估工具之间不存在差异。
队列研究（诊断）；证据等级，2级。
共纳入207例经关节镜证实为半月板撕裂的连续患者（平均±标准差：年龄，52.6±14.3岁）。术前获得3种膝关节功能和生活质量评分：KOOS、WOMAC和WOMET。术后比较问卷的相对结果评分。
总分（相对评分）如下：KOOS为234.2±92.5（55.7%），WOMAC为132.6±54.3（55.5%），WOMET为113±30.8（71%）。WOMET的相对评分结果显著高于WOMAC和KOOS（均P<0.01），而WOMAC和KOOS之间未发现显著差异（P = 0.735）。
与WOMAC和KOOS相比，WOMET能更有效地评估半月板撕裂患者与健康相关的生活质量。因此，推荐使用WOMET评估半月板撕裂患者的膝关节功能和生活质量受损情况。
