Genicular Artery Embolization (GAE) — Minimally Invasive Chronic Knee Pain Treatment in San Antonio

GAE is a minimally invasive outpatient procedure that reduces blood flow to the inflamed lining of the knee joint, easing pain without surgery. Knee replacement is major surgery that removes and replaces the damaged joint with an artificial one, requiring hospital admission and weeks of rehabilitation. GAE involves no incision, no hospital stay, and a much faster recovery. It is a good option for patients who are not ready for or want to avoid knee replacement, and it can even help patients who still have pain after a replacement.

No. The procedure is done under IV conscious sedation, so you are awake but relaxed and comfortable throughout. A small catheter is guided to the genicular artery, so there is no large incision. Most patients feel only mild soreness or bruising at the access site for a few days afterward.

Most patients get relief lasting three to five years. Pain reduction usually develops gradually over two to six weeks as the inflammation in the joint settles down. Because GAE addresses the source of inflammation rather than just masking pain, the relief tends to be durable.

This depends on your specific case and is something Dr. Gianis will determine during your consultation and imaging review. Treatment plans are built around your anatomy and symptoms. Call 210-622-8000 to discuss whether treating both knees is right for you.

GAE does not burn any bridges. Because it is minimally invasive and does not alter the joint itself, you remain a candidate for other treatments, including knee replacement surgery, if needed. Dr. Gianis reviews your imaging and history first to confirm you are a good candidate, which helps set realistic expectations before the procedure.

Most patients go home the same day and return to light daily activities within one to two days. If your job is not physically demanding, many patients return quickly, though your timeline depends on your work and how you feel. Some mild soreness in the first few days is normal, and follow-up appointments track your progress.
