Abstract
PurposeThe purpose of the current study is to evaluate the reliability and quality of the educational content of YouTube videos about anterolateral ligament (ALL). MethodsA standard search was performed on the YouTube database. All English-language videos were included for analysis. Video reliability was assessed with the use of the DISCERN tool, the Journal of American Medical Association (JAMA) benchmark criteria, and the Global Quality Score (GQS). Data regarding the duration of the videos, the date of publication, and the number of likes and views were collected. Furthermore, videos were categorized based on video source (health professionals, company, private user), the type of information (surgical technique, overview, anatomy, radiology and patient experience) and video content (education, patient experience/testimony). ResultsA total of 94 videos were included in the analysis. Eighty-eight (93.6%) videos were published by health professionals, while 4 (4.3%) were published by companies and 2 (2.1%) were published by private users. Most of the videos were about surgical technique (57.4%), and almost all the videos (98.9%) had an educational aim except one that reported a patient experience (1.1%). The mean length of the videos was 648.4±973.5 seconds, and the mean online period was 34.5±27.0 months. The mean DISCERN score, JAMA score and GQS were 32.9±15.9, 1.5±0.9 and 2.3±1.0, respectively. Videos that provided an overview of the ALL were the best in terms of all quality scores and were significantly higher quality than videos about surgical technique and anatomy, radiology and patient experience for all the scores (p<0.001). No difference was found between surgical technique and anatomy, radiology and patient experience (DISCERN score p>0.99; JAMA score: p=0.839; GQS: p>0.99). ConclusionsThe educational content of YouTube videos about the anterolateral ligament of the knee showed low quality and validity based on the DISCERN, JAMA and GQS scores.
