Individuals seeking information about platelet-rich plasma (PRP) treatment for knee osteoarthritis, a controversial topic, may turn to YouTube. However, the quality and content adequacy of these videos should be questioned. This study analyzed YouTube videos related to PRP to evaluate their quality and content. The primary aim was to assess these videos' quality and content, while the secondary aim examined the relationship between video quality/content and video characteristics, information sources, and themes. A total of 250 videos related to PRP treatment for knee osteoarthritis were identified through YouTube searches, and 68 of them were included in the study. The number of views, number of days since upload, view ratio, video duration, number of comments, the source of the information presented in the video, and the overall theme of the video were recorded. The quality and content of the videos were evaluated using the DISCERN, Journal of the American Medical Association, Global Quality Score, and PRP scoring systems. Median scores for video quality and adequacy were: DISCERN: 48 (range: 19-76), Journal of the American Medical Association: 2 (range: 1-4), Global Quality Score: 3.5 (range: 1-5), and PRP score: 6 (range: 2-10). Video quality and content positively correlated with the number of views, view ratio, duration, and comments. Videos in which patients provided the information had the lowest scores in terms of quality and content. While sports medicine physicians generally achieved higher scores, no difference was found between orthopedic surgeons and other specialized physicians. This study has shown that YouTube videos related to PRP treatment for knee osteoarthritis are not of low quality. The positive correlation between video characteristics, such as the number of views and comments, and quality suggests that the YouTube algorithm may prioritize higher-quality content, potentially enabling individuals to access better videos. Physicians provided higher-quality content compared with patients, although differences were observed among medical specialties. This finding suggests that the quality of informative content on PRP may vary depending on the expertise of the content creator. Despite certain limitations, YouTube may serve as a useful resource for individuals seeking information about PRP treatment. However, for the most reliable information, academic sources with an editorial process should be consulted.
寻求有关膝关节骨关节炎富血小板血浆（PRP）治疗信息的个人，这是一个有争议的话题，他们可能会求助于YouTube。然而，这些视频的质量和内容完整性值得质疑。本研究分析了与PRP相关的YouTube视频，以评估其质量和内容。主要目的是评估这些视频的质量和内容，次要目的是研究视频质量/内容与视频特征、信息来源和主题之间的关系。通过YouTube搜索，共识别出250个与膝关节骨关节炎PRP治疗相关的视频，其中68个纳入研究。记录了视频的观看次数、上传天数、观看比例、视频时长、评论数量、视频中呈现信息的来源以及视频的总体主题。使用DISCERN、《美国医学会杂志》全球质量评分和PRP评分系统对视频的质量和内容进行评估。视频质量和完整性的中位数得分分别为：DISCERN：48（范围：19 - 76），《美国医学会杂志》：2（范围：1 - 4），全球质量评分：3.5（范围：1 - 5），PRP评分：6（范围：2 - 10）。视频质量和内容与观看次数、观看比例、时长和评论数量呈正相关。患者提供信息的视频在质量和内容方面得分最低。虽然运动医学医生的得分通常较高，但骨科医生和其他专科医生之间未发现差异。本研究表明，与膝关节骨关节炎PRP治疗相关的YouTube视频质量并不低。视频特征（如观看次数和评论数量）与质量之间的正相关表明，YouTube算法可能会优先推荐高质量内容，这可能使个人能够获取更好的视频。与患者相比，医生提供了更高质量的内容，尽管在医学专科之间存在差异。这一发现表明，关于PRP的信息性内容质量可能因内容创作者的专业知识而异。尽管存在某些局限性，但YouTube可能是寻求PRP治疗信息的个人的有用资源。然而，为获取最可靠的信息，应参考经过编辑流程的学术来源。
