Knee osteoarthritis pain relief lasts 12 months with artery embolization
A real-world study of 194 knee osteoarthritis patients undergoing genicular artery embolization (GAE) with rapidly resorbable gelatin microspheres showed meaningful pain reduction and improved function for up to 12 months, with pain scores dropping from 7/10 to 3 and 80% exceeding the minimum clinically important difference; the procedure was safe with mostly mild, self-limited adverse events in 6.7% of participants, offering a non-surgical option between injections and joint replacement.
