Aim: Intra-articular knee injections are frequently applied interventions in clinical practice. YouTube is the most popular video-sharing Web site that can be accessed as an information source. In this study, we aim to examine the educational value of the videos about intra-articular knee injections on YouTube.
Material and Methods: The YouTube database was searched using the “intra-articular knee injection” keyword. A total of 55 videos having the inclusion criteria, were analyzed. Four independent reviewers assessed videos for procedural technique and educational quality using a 5-point Global Quality Scale (GQS). To evaluate the reliability the 5-point Discern scale was used.
Results: The mean duration of the videos was 3.9 (± 3.8) minutes. Approximately 236.2 (± 231.3) people watched each video. The mean number of daily views was 58.6 (± 130.5). The most common indication was osteoarthritis (43.6%) and the most common injection material were corticosteroids (40%). The most populer approaches were superolateral (27.3%) and anterolateral (25.5%). 43.6% of the patients underwent complete sterile injection. The mean reliability score was 1.58 (± 1.1) and the mean GQS score was 2.47 (± 1.0).
Conclusions: Web-based learning applications related to intra-articular knee injections are becoming increasingly common. Unfortunately, we thought that YouTube content had an insufficient and inconsistent educational quality even though when it was published by healthcare professionals. Therefore, it is very important to examine these videos in terms of reliability and GQS before using them for educational purposes. Creating high-quality videos that meet these criteria seems to be a necessity of modern medical education.
