Do Diagnostic Genicular Nerve Blocks Predict Treatment Outcomes for Cooled Radiofrequency Ablation in Patients with Chronic Knee Pain from Osteoarthritis: A Prospective Randomized Trial
Genicular nerve radiofrequency ablation (RFA) is a promising treatment for patients with chronic pain from knee osteoarthritis (OA). Little is known about factors that predict treatment success or the prognostic utility genicular nerve blocks prior to genicular nerve RFA. In the case of zygaphophyseal and sacroiliac joint-mediated pain, multiple studies have confirmed the ability of diagnostic nerve blocks to predict short and long-term outcomes of RFA. The current study evaluated the utility of diagnostic genicular nerve blocks to predict clinical outcomes of genicular nerve cooled radiofrequency ablation (cRFA) in patients with OA.
