Genicular Artery Embolization Using Rapidly Resorbable Gelatin-based Microspheres for Osteoarthritis-related Knee Pain

Listen to this summary

This study investigates the safety and clinical outcomes of genicular artery embolization (GAE) using rapidly resorbable gelatin-based microspheres (RRGMs) in patients with osteoarthritis-related knee pain who have not responded to conservative treatments. The results indicate that GAE with RRGMs is safe, with no severe adverse events, and leads to significant pain reduction and improvement in knee function over a 12-month follow-up period.
