What is Genicular Artery Embolization (GAE)?
Genicular Artery Embolization (GAE) is an outpatient, minimally invasive, non-surgical procedure for the treatment of pain for mild to moderate osteoarthritis (OA).
The GAE procedure safely reduces excess arterial blood flow to the inflamed synovial lining of the knee from OA.
Reducing the synovial inflammation can provide fast and longer term pain relief for OA patients. This pain improvement limits the need for oral pain medication, joint injections and can allow your return to a more active lifestyle.
The GAE procedure:
GAE is performed by an Interventional Radiologist (IR), a doctor who uses imaging guidance to see structures inside the body and treat conditions without surgery. During the GAE procedure you are given sedation medication but remain awake.
A small catheter is used to access an artery at the top of your thigh. (Using x-ray imaging) the catheter is directed to the genicular artery and specific branches are selected that lead to the inflamed vessels supplying the lining of the knee (synovium). Tiny particles are injected into the inflamed vessels. These particles will reduce blood flow and decrease inflammation, providing significant pain relief in majority of patients. Patients go home the same day.
