Results of genicular nerve ablation by radiofrequency in osteoarthritis-related chronic refractory knee pain

Abstract

Background/aim: The aim of this study was to investigate the medium- to long-term effects of radiofrequency RF ablation of genicular nerves for chronic refractory knee pain due to osteoarthritis OA .Materials and methods: Forty-eight patients who underwent RF ablation of the genicular nerves were evaluated retrospectively. The visual analogue scale VAS score, Western Ontario and McMaster universities osteoarthritis index WOMAC index , opioid and nonsteroidal antiinflammatory drug NSAID use score, quality of life score, and treatment satisfaction score were examined at 1, 3, and 6 months after the procedure.Results: The mean VAS scores were significantly lower at the 1-, 3-, and 6-month evaluations compared with the preoperative values P
