The offered therapy known as genicular artery embolization (GAE). The genicular arteries have a number of branches that type a community across the knee joint. These vessels are altered in sufferers affected by osteoarthritis.
In GAE, an interventional radiologist injects small particles into chosen branches that correspond to the positioning of knee ache to dam blood stream to that space.
