Assessment of Information Quality and Reliability of YouTube Videos on Chondrosarcoma

Background: YouTube is increasingly used by patients as a source of health information. However, the accuracy and reliability of shared medical content remains questionable. The aim of this study was to evaluate the information quality, reliability, and popularity of YouTube videos related to chondrosarcoma. Methods: In March 2025, a systematic search was conducted on YouTube using the English keywords "chondrosarcoma" and "chondrosarcoma surgery". After applying exclusion criteria and removing duplicates, 65 videos were included. Videos were independently evaluated by two orthopaedic surgeons regarding uploader type, duration, view count, like count, and days since upload. Video popularity was assessed using the view ratio and Video Power Index (VPI). Information quality and reliability were evaluated using the DISCERN instrument and Journal of the American Medical Association (JAMA) benchmark criteria. Statistical analyses included the Shapiro–Wilk test, Kruskal–Wallis test, and Spearman correlation analysis (p < 0.05). Results: The mean DISCERN score was 33.46±12.64 and the mean JAMA score was 1.45±0.73. The majority of videos were rated as moderate, poor, or very poor quality. Physician-uploaded videos had significantly higher DISCERN and JAMA scores (p = 0.001 and p = 0.021, respectively). No significant association was found between video popularity and information quality. A strong positive correlation was identified between DISCERN and JAMA scores (rho = 0.702, p < 0.001). Conclusions: YouTube videos on chondrosarcoma are predominantly of low quality and reliability. Academic institutions and professional societies should prioritise evidence-based video content production to improve patient education on this rare malignancy.
