Genicular artery embolization (GAE) is a minimally invasive procedure used to treat chronic knee pain caused by osteoarthritis or other degenerative conditions of the knee joint. During the procedure, tiny particles are injected into the genicular arteries that supply blood to the inflamed synovium, in order to block them and reduce inflammation and pain.
The success rate of GAE can vary depending on several factors, including the severity of osteoartrhritis and experience of the interventional radiologist performing the procedure. However, studies have shown that GAE can be an effective treatment option for chronic knee pain, with success rates ranging from 70-90% in reducing pain and improving mobility.
A study published in the Journal of Vascular and Interventional Radiology in 2020 evaluated the long-term outcomes of GAE in 111 patients with chronic knee pain. The study found that the success rate of GAE was 90% at 3 months, 83% at 6 months, and 80% at 12 months, with no significant adverse effects reported.
In a second study of 40 patients with debilitating knee osteoarthritis published in the Journal of Bone and Joint Surgery in 2021 showed results of 68% of patients had more than 50% decrease in pain scores which is significant pain reduction.
Overall, GAE can be a promising treatment option for chronic knee pain. It is important for patients to discuss the potential risks and benefits with their healthcare provider to determine if it is the right choice for them.
