Anterior cruciate ligament (ACL) injuries and ACL reconstruction (ACLR) surgery are very common. Patients increasingly use social media platforms like YouTube to find healthcare information to help them make medical decisions. The purpose of this study was to evaluate the quality of YouTube videos providing information about ACL injuries and ACL surgery.
The most-viewed YouTube videos for ACL-associated search terms were reviewed for inclusion and assessed by two authors using four video quality assessment tools: the Journal of American Medical Association benchmark (JAMA) (0-4), Global Quality Score (GQS) (1-5), modified DISCERN (mod-DISCERN) (0-5), and YouTube ACL Specific Score (the score) (0-25). Intraclass correlation coefficients (ICCs) were calculated to determine interrater reliability. Unpaired t-tests were used for comparisons between groups and linear regressions to identify associations.
There were 45 videos that met the inclusion criteria. Overall, 31.1% of videos reported an academic affiliation, and 53.3% listed an MD as the lead author. The mean JAMA score was 2.8, GQS 3.2, mod-DISCERN 2.6, and overall the score 5.9. There was good interobserver agreement across all quality tools (ICC>0.75). Videos with an MD lead author had significantly higher JAMA (p < 0.001) and GQS (p < 0.01) scores than those led by non-physicians. Videos with academic affiliations had significantly higher JAMA (p < 0.001), GQS (p < 0.01), mod-DISCERN (p < 0.01), and the score Management Domain (p = 0.04) scores.
Among the most-viewed YouTube videos related to ACL injuries and ACL surgery, physician-led and academically affiliated videos provided higher quality educational information compared to other sources, however, the overall quality of content provided is low.
Level IV.
前交叉韧带（ACL）损伤和ACL重建（ACLR）手术非常常见。患者越来越多地使用YouTube等社交媒体平台来查找医疗信息，以帮助他们做出医疗决策。本研究的目的是评估YouTube上提供有关ACL损伤和ACL手术信息的视频质量。
对ACL相关搜索词观看次数最多的YouTube视频进行纳入审查，并由两位作者使用四种视频质量评估工具进行评估：美国医学会基准（JAMA）（0 - 4）、全球质量评分（GQS）（1 - 5）、改良的DISCERN（mod-DISCERN）（0 - 5）和YouTube ACL特定评分（分数）（0 - 25）。计算组内相关系数（ICC）以确定评分者间的可靠性。使用不成对t检验进行组间比较，并使用线性回归来确定关联。
有45个视频符合纳入标准。总体而言，31.1%的视频报告了学术机构隶属关系，53.3%将医学博士列为第一作者。JAMA评分的平均值为2.8，GQS为3.2，mod-DISCERN为2.6，总体分数为5.9。在所有质量工具中观察者间一致性良好（ICC>0.75）。医学博士作为第一作者的视频的JAMA评分（p < 0.001）和GQS评分（p < 0.01）显著高于非医生主导的视频。有学术机构隶属关系的视频的JAMA评分（p < 0.001）、GQS评分（p < 0.01）、mod-DISCERN评分（p < 0.01）和分数管理领域评分（p = 0.04）显著更高。
在与ACL损伤和ACL手术相关的观看次数最多的YouTube视频中，与其他来源相比，医生主导和有学术机构隶属关系的视频提供了更高质量的教育信息，然而，所提供内容的总体质量较低。
四级。
