The aim of this study was to explore physiotherapy-based osteoarthritis (OA) research conducted in South Korea, focusing on the utilisation of non-surgical management and its alignment with international clinical practice guidelines (CPGs). Databases (MEDLINE, EMBASE, CINAHL and SPORTDiscus – accessed via EBSCOhost) and Google Scholar were searched to identify clinical articles and trials focused on research related to OA management in physiotherapy conducted in South Korea. A total of 11 studies met the inclusion criteria – nine were randomised controlled trials, one utilised a prospective design and one adopted a quasi-experimental approach. These studies employed various interventions such as kinesiology tape, electrotherapies, and exercise. None of the studies implemented education, self-management, and weight control as management. There is a discrepancy between research-based physiotherapy for OA management in South Korea and international CPGs. These findings may be explained by factors such as education, healthcare systems, and cultural differences.
