Genicular artery embolization offers minimally invasive alternative to knee replacement for osteoarthritis
↗
Genicular artery embolization reduces chronic knee pain by blocking blood flow to inflamed areas using tiny beads.
The procedure provides a clinical middle ground for patients who have failed conservative treatments but are not ready for major surgery. It targets inflammation rather than replacing the joint, potentially delaying the need for total knee replacement.

The procedure uses a catheter to release tiny beads into blood vessels associated with inflammation.
Benefits may last two to four years for patients who respond well to the treatment.
The FDA has granted breakthrough device status to several devices used in this procedure since 2021.
THE READ
What the cluster adds up to.
Genicular artery embolization (GAE) functions by reducing blood flow to inflamed regions of the knee to lower swelling and pain. The process is performed under conscious sedation and takes one to two hours, involving a small incision in the leg crease. A catheter is guided via the femoral artery using contrast dye and X-ray imaging to target specific vessels.
Adopting this treatment involves a shorter recovery period compared to total knee replacement, as it is an outpatient procedure. Patients are monitored for several hours and typically return home the same day. The primary cost to the patient is a period of a few days of reduced activity following the intervention.
The procedure is most effective for those with mild to moderate knee osteoarthritis. While patients with more advanced disease can undergo GAE, the benefits may not last as long in those cases. Approximately 70% of patients report significant results, including pain scores being cut in half or eliminated entirely.
