Genicular Radiofrequency Ablation Efficacy in Achieving Total Knee Pain Reduction Trial

• Status: Not yet recruiting
• Trial end date: 0000-00-00
• Target enrollment: 60
• Participant gender: Both

Summary

Given the benefits of genicular nerve radiofrequency ablation (RFA) in improving pain and functional status in non-surgical patients with knee osteoarthritis as well as the high prevalence of postoperative pain from total knee arthroplasty (TKA), this study is designed to determine the efficacy of preoperative genicular nerve RFA in improving acute and chronic postoperative pain as well as functional status in patients undergoing TKA. Patients will be randomized to one of two study arms: RFA group (genicular nerve thermal RFA) or control group (RFA needles placed in proper location without effective neurotomy).
