  • Assessed video quality using the DISCERN scoring system.
  • Collected data on likes, views, comments, and creator type.

Main Results:

  • 234 videos averaged nearly 700,000 views; 41% were rated as poor quality.
  • Videos with medical recommendations had higher engagement but were often from non-physicians.
  • Physician-created videos generally scored higher in quality.

Conclusions:

  • Non-physician creators frequently share inaccurate knee injury information on TikTok.
  • Physicians need to increase their presence to provide reliable digital health education.
  • Patients consume a wide range of content, necessitating critical evaluation of online health information.
