Evaluation of the reliability and quality of videos pertaining to the triangular fibrocartilage complex on popular online platforms: A cross-sectional analysis
Year: 2026
Type: article
Abstract: Video platforms are major sources of health information; however, the accuracy of musculoskeletal content is uncertain. Triangular fibrocartilage complex (TFCC) injury is common, and many patients seek guidance online. The present study aims to evaluate TFCC-related videos on Bilibili and TikTok to measure dissemination, quality, and reliability, and to identify features associated with higher-quality content. This study conducted a systematic screening and assessment of videos related to the TFCC on the Bilibili and TikTok platforms. Video characteristics were collected, and quality was assessed by Global Quality Score, modified DISCERN, and Journal of the American Medical Association (JAMA) benchmark criteria. A total of 211 TFCC-related videos were analyzed. TikTok exhibited higher dissemination metrics (likes, comments, collections, and shares; P < .001) but a shorter duration than Bilibili. TikTok also hosted a higher proportion of medical professionals (51% vs 27%) and demonstrated significantly higher JAMA benchmark criteria scores (P = .04). Videos from orthopedic and rehabilitation specialists achieved superior Global Quality Score, modified DISCERN, and JAMA scores (P < .001) compared to nonmedical uploaders. Video length correlated positively with quality on Bilibili (r = 0.39, P < .05), whereas engagement metrics did not correlate with information quality. Video quality and reliability of TFCC-related content varied by platform and creator, although the overall quality remained suboptimal. TikTok videos achieved broader reach and higher average quality, whereas medical professionals produced the most reliable content. Uploaders should ensure accuracy, originality, and clarity, while platforms should refine algorithms to highlight evidence-based videos.
