Genicular Artery Embolization for Osteoarthritis

Genicular artery embolization (GAE) is a minimally invasive procedure used primarily to treat knee pain associated with conditions like osteoarthritis. The technique focuses on reducing inflammation and pain by targeting the small arteries that supply blood to the knee joint. How Genicular Artery Embolization Works: - Targeting Blood Flow: GAE involves the selective occlusion of the genicular arteries, which are responsible for supplying blood to the synovial membrane of the knee. The procedure aims to reduce the blood flow that contributes to inflammation and swelling in arthritic knees. Procedure Details: - Imaging Guidance: The procedure is performed under imaging guidance, typically using fluoroscopy (a type of real-time X-ray imaging). This helps in precisely mapping the arteries that need to be targeted. - Catheter Insertion: A catheter is inserted through a small incision, usually in the groin or wrist. The catheter is then navigated to the genicular arteries of the knee. - Embolization Agent: Through the catheter, an embolic agent (such as microspheres or particles) is delivered to block these arteries. This reduces the blood flow to the inflamed tissue. Benefits of GAE - Minimally Invasive: As a minimally invasive procedure, GAE offers a quicker recovery time compared to traditional knee surgery. - Pain Reduction: Most patients experience significant reductions in pain following the procedure. - Mobility Improvement: Reduced pain and inflammation often lead to improved knee function and mobility.
