Genicular Artery Embolization (GAE) is a minimally invasive, catheter-based treatment for osteoarthritis knee pain that persists despite medications, therapy, braces, or injections. Through a tiny puncture in the wrist or groin, a microcatheter is guided to the genicular (knee) arteries and microscopic particles are delivered to reduce excess blood flow that drives inflammation—helping decrease pain and improve function. Most patients don’t need general anesthesia and recover quickly.
Before GAE, we review your history and imaging to confirm candidacy. The procedure typically takes 45–90 minutes with local numbing and light sedation; most people go home the same day and notice improvement over days to weeks. As with any procedure, risks exist (e.g., bruising, bleeding, temporary skin changes, contrast reaction, infection, or non-target embolization), but serious complications are uncommon. GAE can complement physical therapy, weight management, and may delay or avoid surgery for some patients.
