Dr. John Smirniotopoulos, an interventional radiologist at Georgetown/MedStar Washington Hospital Center, discusses the intricacies of genicular nerve ablation (GNA) for pain management in patients with osteoarthritis and post-surgical knee pain. He delves into the history and evolution of GNA, outlines the neurovascular anatomy, and explains his specific rationale for targeting various nerves for ablation.
