Comparison of Denervation Techniques for the Treatment of Knee Osteoarthritis: Continuous Ablative Radiofrequency Vs. Chemical Denervation with Absolute Alcohol

288 patients around the world
Available in Brazil
This randomized clinical trial compares continuous ablative radiofrequency and chemical denervation with absolute alcohol for pain relief in patients with knee osteoarthritis refractory to conventional treatments. Participants will be randomly assigned to one of the two procedures, with outcomes assessed based on pain reduction, functional improvement, quality of life, and safety. Follow-ups will be conducted for up to six months to evaluate the durability of pain relief, providing evidence to guide clinical management of chronic knee osteoarthritis pain.
