Could This Replace a Knee Replacement? A Surgeon Investigates

🌐 thesurgeonunmasked.com Genicular artery embolization (GAE) — can it replace a knee replacement? An orthopedic surgeon and an interventional radiologist break down the real evidence. When the Society of Interventional Radiology endorsed genicular artery embolization (GAE) as part of standard care for knee osteoarthritis, I wanted to understand it for myself. I'm an orthopedic surgeon who replaces knees — and a knee replacement patient myself — so I brought in interventional radiologist Dr. Connie Hsu, a Fellow of the American College of Radiology who performed the first GAE in the Austin area, to break it all down. GAE works by targeting the abnormal new blood vessels that drive inflammation and pain in an arthritic knee — "pruning" them with tiny particles (about the size of grains of sand) while leaving the knee's main blood supply intact. We cover who's a candidate, the evidence (including sham-controlled trials), how long relief lasts, safety and recovery, cost and Medicare coverage, and my honest take as a knee surgeon on whether this is competition or a complement. Short version: it's a useful adjunct that fits between conservative care and surgery — and it reduces pain, it doesn't eliminate it. ⚠️ This video is patient education, not medical advice. It is not a substitute for evaluation by your own physician. Always follow the guidance of your own doctor, and in an emergency call 911.
