Bibliometric and Visualized Analysis of the Global Research Status and Trends of the Association Between Vitamin D and Osteoarthritis in the Last Two Decades

Publication volume on vitamin D and OA increased steadily in the last two decades. Research focus evolved from basic bone metabolism to specific vitamin D metabolites and inflammation mechanisms. Investigations continue into vitamin D's role in specific OA phenotypes and inflammatory pathways. The underrepresentation of low and middle-income countries represents a critical research gap. Recent research explores vitamin D's potential for managing OA symptoms, with future work likely focusing on its biochemical and clinical effects in OA treatment.
