  Abstract: Objective: To investigate the current status, research hotspots, and future development trends of fire needle therapy in the treatment of knee osteoarthritis (KOA). Methods: Randomized controlled trials on fire needle treatment for KOA published between January 2001 and September 2025 were retrieved from the CNKI, Wanfang, VIP, and SinoMed databases. CiteSpace 6.4 software was used to conduct a bibliometric analysis of authors, institutions, and keywords. Results: A total of 257 articles were included. The author collaboration network indicated that Meng Aixia, Liu Yanwei, etc., were the main researchers, but a stable core author team has not yet formed. Research institutions were primarily universities of traditional Chinese medicine and their affiliated hospitals, with limited cross-regional collaboration. High-frequency keywords included fire needle, filamentary fire needle, warm needle moxibustion, clinical efficacy, inflammatory factors, etc. Keyword clustering results showed that research hotspots focused on treatment methods, efficacy evaluation, and mechanisms of action (such as changes in inflammatory factors). Burst word analysis suggested that research trends have gradually shifted from early technical exploration to efficacy verification and further deepened into mechanism research. Conclusion: Research on fire needle treatment for KOA follows a development path of technique – efficacy – mechanism. Current hotspots focus on the improvement of filamentary fire needle techniques, clinical efficacy evaluation, and related inflammatory mechanism research. In the future, multicenter, large-sample clinical studies should be promoted, and the exploration of mechanisms of action should be continuously deepened.
