This sample size was determined a priori via power analysis to detect a moderate effect. Two authors independently extracted video characteristics and engagement metrics and scored content quality using DISCERN, Principles for Health\u2010related Information on Social Media (PRHISM) and ACL Exercise Education Score (ACLEES) scoring systems. Disputes were resolved via author consensus. Interrater reliability was assessed using Cohen's\n                      <jats:italic>\u03ba<\/jats:italic>\n                      .

Median scores were 30 (interquartile range [IQR] 24\u201338) for DISCERN, 13 (IQR 10\u201316) for PRHISM and 10 (IQR 6\u201315) for ACLEES, all indicating poor overall quality. Domain analysis revealed that content was generally accessible and relevant yet lacked citation of evidence and follow\u2010up information. Post length significantly correlated with all three scoring systems. Self\u2010identified healthcare professionals achieved significantly higher PRHISM scores than general users in authorship, authority and financial disclosure domains. No differences were found in engagement metrics or in DISCERN and ACLEES scores between the two groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\n                      Primary ACL injury prevention content on\n                      <jats:italic>TikTok<\/jats:italic>\n                      is widely viewed, accessible and relevant, but generally of poor quality among both healthcare professionals and general users.
