A non-surgical procedure that temporarily blocks extra blood vessels in the knee has shown significant promise in providing lasting pain relief for people with knee osteoarthritis. In a clinical study of 194 patients, 80% reported significant reductions in knee pain that lasted for at least a full year after receiving the treatment.
The procedure, known as genicular artery embolization (GAE), addresses the underlying causes of osteoarthritis-related knee pain. Osteoarthritis wears down joint cartilage and causes the body to grow unnecessary new blood vessels around the knee, leading to increased inflammation and irritation of surrounding nerves. By temporarily clogging excess blood vessels with microscopic gelatin particles, doctors can reduce inflammation and quiet pain-sensing nerves without major surgery or permanent implants.
Researchers at Charité-Universitätsmedizin Berlin, led by Deputy Head of Interventional Radiology Florian Nima Fleckenstein, M.D., conducted the study. They found that GAE was a safe and minimally invasive therapy that provided meaningful pain relief and functional improvement in participants with osteoarthritis-related knee symptoms for at least 12 months. The study participants experienced significant reductions in pain and improvements in daily mobility, including easier walking, climbing stairs, and bending.
While the results are promising, researchers note several important limitations. The study did not include a control group receiving a mock or placebo procedure, making it difficult to isolate the physical benefits of the dissolvable particles from potential placebo effects. Additionally, the study tracked patients for only one year, and further research is needed to determine how long the pain relief typically lasts and how often repeat treatments might be required.
