Historic First: Genicular Artery Embolization Performed in Cape Town Using NexSphere
In a landmark moment for interventional radiology in South Africa, the first Genicular Artery Embolization (GAE) procedure in Cape Town was successfully performed in February 2026, utilising the NexSphere microsphere embolization platform. GAE is a minimally invasive, catheter-based procedure that targets the abnormal blood vessels supplying the synovial lining of the knee joint in patients with mild-to-moderate osteoarthritis. By reducing the hypervascularity and associated neovascularisation that drive chronic joint pain and inflammation, GAE offers meaningful symptomatic relief for patients who are not yet surgical candidates or who wish to avoid joint replacement surgery. The procedure was performed using NexSphere, a precision microsphere platform specifically designed to deliver controlled, predictable embolization. NexSphere microspheres are calibrated to ensure accurate vessel sizing and consistent occlusion depth, minimising the risk of non-target embolization — a critical consideration in the delicate vascular anatomy surrounding the knee. "This is an exciting clinical development for South Africa," said a Virtumed spokesperson. "GAE has an established evidence base internationally, and we are proud to support local specialists in bringing this option to patients who currently have limited non-surgical choices for managing knee osteoarthritis." The successful completion of this first case in Cape Town represents a significant milestone in expanding the interventional treatment landscape for musculoskeletal conditions in South Africa. Virtumed remains committed to enabling access to evidence-based, minimally invasive therapies and to supporting the clinicians who deliver them. Virtumed will be providing ongoing clinical support and education to centres wishing to establish a GAE programme, as demand for this procedure continues to grow nationally.
