The purpose of this study is to determine if patients with chronic painful knee osteoarthritis experience meaningful and long-term improvement in pain, function, and analgesic use after ultrasound-guided pulsed radiofrequency of the genicular nerves following a double diagnostic genicular nerve blocks.

Exclusion: Previous radiofrequency ablation treatment for similar symptoms; Intra-articular knee corticosteroid or hyaluronic acid injection in the past 3 months; Previous knee joint replacement surgery; Active systemic or local infections at the site of proposed needle and electrode placement; Coagulopathy or other bleeding disorder; Unstable medical or psychiatric illness; The patients with secondary osteoarthritis of knees; Associated systemic arthropathies, e.g. rheumatoid arthritis and gout; Cognitive deficit; Patients missing two or more appointments consecutively were excluded from the study.
