Is short video platform a high-quality source of information on Arthrochondral Injury?: A Cross-Sectional Study in Mainland China (Preprint)

BACKGROUND Information about orthopedic diseases on the Internet has not been extensively evaluated. OBJECTIVE Our purpose was to collect and evaluate online information on arthrochondral injury on the current video-sharing platforms in mainland China. METHODS Four independent researchers used the Microsoft Edge web browser in July 2024. Information and data of those videos were recorded and a descriptive analysis was performed. RESULTS After data extraction, Ninety-nine videos (48 on TikTok and 51 on Bilibili) involved in the search results met the criteria. Most of the videos were low quality. The most common uploader profile was orthopedic surgeons. The most common content in the videos were introduction, while surgical techniques had the least results. The mean DISCERN, JAMA, and GQS scores were 34.4, 2.8, and 2.9, respectively. Higher quality videos had longer duration and better reliability scores. CONCLUSIONS The videos on TikTok and Bilibili, although abundant, are extremely lacking in comprehensiveness and professionalism. Those videos can be effective in increasing public awareness of arthrochondral injury. The lower proportion of expertise and poor quality may make the videos insufficient in medical education. The quality of videos uploaded by orthopedic surgeons is not superior to that of other creators. In the future, more orthopedic surgeons need to participate in online video creation while addressing the issues of poor quality and popularity.
