For the past decade, a minimally invasive ablation relying upon genicular radiofrequency has been gaining popularity as a treatment for the condition. To date, however, the literature contains only limited data supporting the effectiveness of this procedure, leading to insurance companies labeling it as \"experimental\" and denying claims. Benefits described include reduced adverse outcomes and complications, quicker recovery and longer duration of analgesia, and broader scope of applicability when compared to other, traditional treatments.</p><p><strong>Objectives: </strong>The present investigation focused on genicular radiofrequency ablation (GRFA) and its outcomes, including disability (e.g., stiffness, physical function), pain, and improvement in patients' quality of life.</p><p><strong>Study design: </strong>This retrospective, single-center study was conducted to evaluate the safety and effectiveness of GRFAs, plus their associated radiofrequency generators and electrode systems.

Thirty-four (34) individuals were enrolled at LSU Health Shreveport, which was the sole investigational site, between March 2021 and 2025. The Stryker SERFAS Energy Platform (Stryker Corporation) was the primary radiofrequency generator selected for genicular ablation (61.9%), with the Avanos RFA Solutions Generator System (Avanos Medical, Inc.) selected for the remaining cases. As for the outcome measures, scores on the visual analog scale (VAS), disability changes measured on the Western Ontario and McMaster Universities Arthritis Index (WOMAC), adverse outcomes, quality of improvement, and ratings recorded in the Quality of Life subsection of the Knee Injury and Osteoarthritis Outcome Score (KOOS) were compared after GRFA.</p><p><strong>Results: </strong>Mean VAS scores for CK pain intensity decreased significantly, dropping by 3.1 cm from a baseline score of 9.0 cm by the specified end (March 18th, 2025). Furthermore, 66.7% of the patients experienced a 20% or greater improvement in pain, 33.3% of the patients experienced a 40% or greater improvement in pain, and 19.1% of the patients experienced a 60% or greater improvement in pain.

Over the past 2 decades, clinicians and researchers have extensively studied and utilized RF for chronic pain management. Despite its growing clinical use, the evidence supporting the efficacy of RF remains inconsistent, with outcomes varying due to differences in study design, patient selection, and procedural techniques. To improve the understanding of the current research landscape, this study conducts a bibliometric analysis with the aim of summarizing and visualizing the evolution of, research hot spots within, and future trends in the use of RF for chronic pain treatment.
