Understanding [genicular artery embolisation](https://www.nbir.com.au/genicular-artery-embolisation) (GAE), if it’s safe and who is a candidate can help you gain some confidence before your treatment, and know if it’s the right option for you. Our guide to what you need to know about GAE will give you general information about this minimally invasive, modern treatment for [osteoarthritis](https://www.nbir.com.au/knee-osteoarthritis). If you have any questions about if it’s suitable for you or your specific circumstances, our team at Northern Beaches Interventional Radiology are only a [call](https://www.nbir.com.au/book-a-consultation)away.     ## About Genicular Artery Embolisation Genicular artery embolisation (GAE) is a modern, minimally invasive treatment used to help provide short and long-term pain relief for people with osteoarthritis in the knee. It works by embolic agents (tiny particles or beads) being inserted into the genicular arteries around the knee via a catheter in the groin area. These particles help restrict blood flow to the lining of the knee, known as the synovium, helping to increase mobility and decrease pain.  The incision area for the catheter is numbed using local anaesthesia, however, you can be sedated if requested to if recommended. As it’s an in-patient treatment, you can return home the same day as having genicular artery embolisation.  [![Asses your knee health with the WOMAC index](https://no-cache.hubspot.com/cta/default/20028993/71e09890-1b8e-4cfe-b2b7-cc978144ad9b.png)](https://cta-redirect.hubspot.com/cta/redirect/20028993/71e09890-1b8e-4cfe-b2b7-cc978144ad9b)   ### Is genicular artery embolisation safe? [Majority of studies](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8612839/) have found genicular artery embolisation to be a safe treatment. There has been an average of less than 1% occurance of skin discolouration, puncture-site hematoma and miscellaneous adverse effects, such as toe numbness and fever. One study of 20 patients saw 13 GAE recipients experience self-limiting skin discoloration — i.e. goes away on its own without treatment. However, most other studies have seen a 0.1% occurrence.    ### Who can perform a genicular artery embolisation? Only an interventional radiologist can perform a genicular artery embolisation. The interventional radiologist will need to use x-rays and other imaging techniques to see inside the body and to be able to manoeuvre the catheter to the treatment site. However, you will need a doctor’s referral for a GAE in Australia, who will typically order diagnostic imaging, such as an MRI or angiography, to diagnose your suitability for treatment.    ## Who is a Candidate for GAE? The ideal candidate for GAE, or genicular artery embolisation, is typically someone with chronic knee pain or knee osteoarthritis who is not a candidate for knee replacement, is not responding to other pain medications and treatments, and/or is looking for a less invasive procedure than surgery. While GAE helps reduce pain in those with osteoarthritis, it is not intended nor can it help with significant joint deformities. Whether you are a candidate for GAE is assessed on a case-by-case basis by your doctor and the performing interventional radiologist.    ### Success Rate of Genicular Artery Embolisation Studies indicate there is a 99.7% technical [success rate of genicular artery embolisation](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9971280/#:~:text=Our%20review%20demonstrated%20that%20GAE,with%20few%20minor%2C%20transient%20complications.). The average patient sees a[significant decrease in pain](https://www.sirweb.org/media-and-pubs/media/news-release-archive/sir-2021-knee-pain-031621/)within the first 3 days, with stable pain reduction in the next 12 to 24 months, depending on the person.  As with all treatments, it’s best to seek personal advice based on your personal circumstances.    ## Is GAE the Non-Surgical Knee Pain Treatment For You? GAE can help many people, but not everyone. Before treatment, your doctor and interventional radiologist will assess if you’re a candidate for treatment, including if you: - Have been diagnosed with osteoarthritis.  - Are seeking a non-surgical knee pain treatment. - Have been unsuccessful or displeased with other treatment options. - Are not a candidate for knee replacement surgery. - Do not have significant joint deformities or need cartilage replacement.
