This study by Riccardo D'Ambrosi and Timothy E. Hewett assesses the validity and informational value of TikTok videos related to the anterior cruciate ligament (ACL). The researchers analyzed 100 TikTok videos, categorizing them by source, subject type, content, and background audio. The videos were evaluated using the DISCERN instrument, JAMA benchmark criteria, and the Global Quality Score (GQS). The results indicate that the educational value of these videos is poor, with low scores on all three quality indices. The number of views, likes, shares, and comments were positively correlated with higher scores, but significant differences were found between videos by private users and those by surgeons. The study concludes that further research is needed due to the rapid growth of TikTok and the potential impact on patient information.This study by Riccardo D'Ambrosi and Timothy E.
