Radio-frequency Ablation in Knee Osteoarthritis by Three Needles Technique

Alaa Fouli Gaber Ebrahim50 enrolled

Overview

The study is designed to evaluate and compare the efficacy of three needles approach as a new technique in radiofrequency neurotomy of genicular nerve versus the traditional single needle approach as a treatment of advanced knee osteoarthritic pain. Primary outcome: 1. Pain intensity via the visual analogue score (VAS). 2. Function and pain via the Oxford Knee Score. Evaluated after 6 months of the procedure Secondary outcome: 1. Failure rate. 2. Incidence of any complication. 3. Total analgesic requirement during the period of follow up.
