Long term effect of ultrasound guided radiofrequency ablation of genicular nerves in chronic knee osteoarthritis

Abstract

Background: Genicular nerve radiofrequency ablation (RFA) was offered as a therapeutic alternative for individuals who have not had success with conservative pain management of knee osteoarthritis (OA) and are either unsuitable candidates for surgery or prefer to avoid total knee replacement. The purpose of this work was to assess long term efficiency of ultrasonography (US) guided RFA of genicular nerves for individuals with chronic knee OA using Arabic translation of Oxford Knee Scale (OKS).3Methods: This prospective randomised clinical work had been performed on 40 participants, both sexes, with symptomatic knee OA, failed knee replacement. All patients were subjected to US -guided Cooled RFA technique overview. Results: There was significant change of OKS after one week, three months and six to twelve months. Changes in modified Mac-Nab criteria were significantly different at different periods of measurements.No patients were referred to surgery during our follow up time. Conclusions: US guided RFA of genicular nerves is efficient and safe technique in management of chronic knee OA.
