YouTube videos on ulnar collateral ligament reconstruction are highly variable in terms of reliability and quality: A quantitative analysis

Background: Ulnar collateral ligament reconstruction (UCLR) is commonly performed on adolescent athletes, who often turn to online sources such as YouTube for health information. The purpose of this study was to retrospectively review the accuracy, reliability, and quality of UCLR videos using validated scoring instruments.Methods: YouTube was queried for "Tommy John surgery," "UCL reconstruction," and "ulnar collateral ligament reconstruction." After categorization by physician, nonphysician/trainer, patient or commercial source, videos were assessed for reliability and quality using the Journal of the American Medical Association (JAMA) benchmark criteria (0-4) and DISCERN tool (16-80).Results: 104 videos were included in the final analysis. 74% of videos (77/104) were made by physicians. The mean JAMA and DISCERN scores for all videos were 3.1 +/- 0.8 and 46.1 +/- 8.5, respectively. The majority of videos were rated as "fair" based on DISCERN score (56/104, 53.8%). JAMA scores were significantly higher for physician videos compared to non-physician videos (3.3 +/- 0.8 vs 2.6 +/- 0.7, p < 0.0001), but no such difference was found for DISCERN scores (46.3 +/- 7.7 vs 45.3 +/- 10.57, p = 0.43).Conclusion: Physicians should be cognizant of the quality and reliability of YouTube videos when instructing patients on information sources related to UCLR.
