Abstract

BACKGROUND: Optimal perioperative nutrition affects outcomes in total joint arthroplasty (TJA), with malnutrition linked to increased complications. While YouTube is a popular platform for patient education, the quality of videos on perioperative nutrition is unknown. This study evaluated the quality and educational value of videos using established and TJA-specific scoring systems. METHODS: A systematic YouTube search with 11 arthroplasty and nutrition-related keywords was performed, excluding sponsored and non-English content. Two reviewers recorded view count, duration, upload age, health-system affiliation, and presenter credentials, then graded quality with Journal of the American Medical Association criteria, Global Quality Score, modified DISCERN, and a novel Joint Replacement Nutrition Score (JRNS). Interrater reliability was evaluated using intraclass correlation coefficients. RESULTS: Of 98 videos identified, 43 met inclusion criteria. Mean view count was 34,751 (range, 2-470,475). Mean duration was 11.2 minutes (range, 0.5-51.4). Health system affiliation was present in 41.9% (18/43), and 32.6% (14/43) were authored by physicians. Quality scores were: Journal of the American Medical Association 2.77 (range, 1-4), Global Quality Score 3.07 (range, 1-5), modified DISCERN 2.83 (range, 1-4), and JRNS 4.64 (range, 0-11), with high interrater reliability (intraclass correlation coefficient range, 0.717-0.922). Quality did not differ by health system affiliation nor presenter credentials. CONCLUSIONS: YouTube videos on TJA perioperative nutrition were generally low to moderate quality, omitting key topics like individualized nutrition, increased caloric needs, and evidence-based supplementation. The novel JRNS demonstrated interrater reliability and highlighted content gaps across available videos. Nonphysician professionals produced some of the most informative videos. The lack of correlation between view count and quality emphasizes the need for higher-quality content to reach patients. Interdisciplinary collaboration is needed to develop comprehensive educational resources on perioperative nutrition for TJA.
