Knee osteoarthritis (OA) affects millions of Americans, and not every patient is amenable to surgery for a variety of reasons. Genicular nerve radiofrequency ablation (GNRFA) is emerging as an effective minimally invasive nonsurgical treatment option for symptomatic knee OA. GNRFA has been shown to provide consistent short-term (3 to 6 months), and sometimes longer, pain relief in patients with symptomatic knee OA or with pain syndrome following total knee arthroplasty. The data are limited to mostly smaller studies on the efficacy and safety of RFA in patients with symptomatic knee OA.
