Osteoarthritis (OA) is a complex condition driven by biomechanical, metabolic and inflammatory factors; however, effective disease-modifying treatments remain unavailable. Growing evidence suggests that gut microbiota dysbiosis has an important role in OA pathogenesis, giving rise to the emerging concept of a functional and targetable gut–joint axis. Gut microbiota dysbiosis can impair enteroendocrine signalling, intestinal immunity and gut barrier integrity, alter the secretion of hormones and cytokines and facilitate the translocation of gut microorganisms, pro-inflammatory molecules and metabolites into the circulation or joints. These processes can disrupt systemic and local homeostasis, promote metabolic dysregulation and obesity, trigger low-grade inflammation and contribute to both the onset and progression of OA. Although these insights open up new avenues for disease-modifying treatments and build on the long-standing paradigm in OA, which primarily focuses on pain relief rath
