Radiofrequency (RF) ablation for knee pain is a minimally invasive procedure used to treat chronic knee pain, commonly from osteoarthritis or post-surgical pain. It works by using radiofrequency energy to heat and deactivate the genicular nerves that transmit pain signals from the knee. A diagnostic nerve block is first performed to confirm the pain source and assess if RF ablation will be effective. The procedure is typically done under local anesthesia with imaging guidance for precise nerve targeting. It usually takes 30–60 minutes and is performed on an outpatient basis. Patients often resume normal activities within a day or two. Pain relief typically begins within 1–4 weeks and may last 6–12 months or longer. RF ablation can significantly reduce pain, improve function, and reduce reliance on medications. It’s a good option for those who haven’t responded well to conservative treatments like injections or physical therapy. cooled radiofrequency ablation for knee pain radio frequency ablation for knee replacement surgery radiofrequency ablation for knee osteoarthritis radiofrequency ablation for knee pain side effects rf ablation of knee dr in chennai
