Description
Summary:Background: Genicular radiofrequency ablation is an established therapy for chronic knee pain. An analysis comparing different probe sizes and technologies has not yet been undertaken for this indication. This large retrospective, comparison study from a single-center comprehensive pain management practice aims to do that. Methods: Outcomes of 170 patients who underwent traditional radiofrequency ablation (tRFA) for chronic knee pain were compared to 170 consecutive patients who received cooled radiofrequency ablation (CRFA) with similar (p=0.5) pre-procedural pain scores. Results: The VAS pain score at the first post-procedure visit at 4-6 weeks decreased to 5.07[+ or -]2.8 cm for tRFA and to 4.26 [+ or -] 3.2 cm for CRFA (p
