Genicular artery embolization (GAE) is a safe and effective treatment for knee pain related to osteoarthritis, however there are several aspects of the procedure technique which may be unique. Familiarity with procedural steps, arterial anatomy, embolic endpoints, technical challenges, and potential complications is imperative for good clinical practice and outcomes. The success of GAE depends on correctly interpreting angiographic findings and variable anatomy, navigating small and acutely angled arteries, recognizing collateral supply, and avoiding non-target embolization. The procedure can potentially be performed for a wide range of patients with knee osteoarthritis. When effective, pain relief can be durable for many years. When done meticulously, adverse events from GAE are uncommon.
