Condition-specific questionnaires are important components in evaluation of outcomes of surgical interventions. No condition-specific study methodological quality questionnaire exists for evaluation of outcomes of articular cartilage surgery in the knee.
To develop a reliable and valid knee articular cartilage-specific study methodological quality questionnaire.
Cross-sectional study.
A stepwise, a priori-designed framework was created for development of a novel questionnaire. Relevant items to the topic were identified and extracted from a recent systematic review of 194 investigations of knee articular cartilage surgery. In addition, relevant items from existing generic study methodological quality questionnaires were identified. Items for a preliminary questionnaire were generated. Redundant and irrelevant items were eliminated, and acceptable items modified. The instrument was pretested and items weighed. The instrument, the MARK score (Methodological quality of ARticular cartilage studies of the Knee), was tested for validity (criterion validity) and reliability (inter- and intraobserver).
A 19-item, 3-domain MARK score was developed. The 100-point scale score demonstrated face validity (focus group of 8 orthopaedic surgeons) and criterion validity (strong correlation to Cochrane Quality Assessment score and Modified Coleman Methodology Score). Interobserver reliability for the overall score was good (intraclass correlation coefficient [ICC], 0.842), and for all individual items of the MARK score, acceptable to perfect (ICC, 0.70-1.000). Intraobserver reliability ICC assessed over a 3-week interval was strong for 2 reviewers (≥0.90).
The MARK score is a valid and reliable knee articular cartilage condition-specific study methodological quality instrument.
This condition-specific questionnaire may be used to evaluate the quality of studies reporting outcomes of articular cartilage surgery in the knee.
特定于病症的问卷是评估手术干预结果的重要组成部分。目前尚不存在专门用于评估膝关节关节软骨手术结果的特定于病症的研究方法学质量问卷。
开发一种可靠且有效的膝关节关节软骨特定于病症的研究方法学质量问卷。
横断面研究。
采用逐步、预先设计的框架来开发一种新的问卷。从最近对 194 项膝关节关节软骨手术研究的系统评价中确定并提取与主题相关的项目。此外，还确定了来自现有通用研究方法学质量问卷的相关项目。生成初步问卷的项目。删除冗余和不相关的项目，并修改可接受的项目。对仪器进行预测试和项目加权。该仪器，即 MARK 评分（膝关节关节软骨研究的方法学质量），用于测试其有效性（标准效度）和可靠性（观察者内和观察者间）。
开发了一个 19 项 3 个领域的 MARK 评分。100 分制评分具有表面效度（8 位骨科医生焦点小组）和标准效度（与 Cochrane 质量评估评分和改良 Coleman 方法学评分有很强的相关性）。总体评分的观察者间可靠性良好（组内相关系数 [ICC]，0.842），MARK 评分的所有单项评分均为可接受至完美（ICC，0.70-1.000）。两名观察者在 3 周间隔内评估的观察者内可靠性为强（≥0.90）。
MARK 评分是一种可靠且有效的膝关节关节软骨特定于病症的研究方法学质量工具。
该特定于病症的问卷可用于评估报告膝关节关节软骨手术结果的研究的质量。
