Anatomic Considerations for Osteoarthritis Treatment Strategies

Genicular artery embolization (GAE) has emerged over the recent years as a minimally invasive alternative for patients with chronic knee pain due to osteoarthritis (OA). A growing body of evidence in the literature continues to support the safety and efficacy of GAE. As more interventional radiologists adopt this service line in their practice, it is imperative to understand the genicular anatomy to optimize technical success. This review aims to summarize the anatomical considerations critical to optimizing outcomes with GAE in patients with knee OA, highlighting its growing role in clinical practice.
