Indian-origin chief of vascular and interventional radiology and an associate professor of radiology at Rutgers New Jersey Medical School, practicing at University Hospital, Abhishek Kumar, along with Rutgers Health experts, has introduced ‘genicular artery embolization’ to treat chronic knee pain.
Genicular artery embolization, a minimally invasive procedure, brings a pathway of hope and healing for patients with long-term knee pain.

The procedure is designed to reduce knee pain caused by osteoarthritis, providing an alternative to operating on the joint itself and instead targeting the tiny arteries that feed inflammation around the knee.
Kumar explained that the procedure involves using a precise catheter going through a small pinhole in the skin, gently blocking abnormal vessels, and reducing that excess blood flow. By doing that, it brings down inflammation, which can significantly lessen pain and improve mobility.
He further mentioned that genicular artery embolization is ideal for patients with moderate to severe knee osteoarthritis whose pain persists despite medications or injections, especially those who are not open to surgery or who cannot have one for medical reasons.
Kumar is dual board-certified in Diagnostic and Interventional Radiology and heads the state's largest clinical and teaching Interventional Radiology practice. He developed the Y90 radioembolization program at University Hospital in 2017 and is an active member of the Society of Interventional Radiology (SIR), serving on several committees and currently the Vice Chair of the SIR Early Career Section.
He is an active mentor to residents and students and serves as the faculty advisor to the Interventional Radiology Interest Group (IRIG) at Rutgers NJMS, and has served as the course director for the annual New Jersey Interventional Radiology Symposium since 2018.
Genicular artery embolization puts Rutgers Health among the region’s earliest academic medical centers to deliver this sophisticated, image-guided treatment for knee osteoarthritis.
