YouTube is a video sharing platform that is a common resource for patients seeking medical information. The objective of this study is to assess the educational quality of YouTube videos pertaining to total knee arthroplasty and knee arthritis. A systematic search for the terms “knee replacement” and “knee arthritis” was performed using Youtube's search function. Data from the 60 most relevant videos were collected for each search term. Videos not in English or those without audio or captions were excluded. Quality assessment checklists with a scale of 0 to 10 points were developed to evaluate the video content. Videos were grouped into poor quality (grade 0–3), acceptable quality (grade 4–7) and excellent quality (grade 8– 10), respectively. Four independent reviewers assessed the videos using the same grading system and independently scored all videos. Discrepancies regarding the scoring were clarified by consensus discussion.PURPOSE
