Osteoarthritis (OA) is a type of joint disease that results from the breakdown of joint cartilage and underlying bone. The most common symptoms are joint pain and stiffness. Initially, symptoms may occur only following exercise, but over time they may become constant. Other symptoms may include joint swelling, decreased range of motion, and, when the back is affected, weakness or numbness of the arms and legs.
Osteoarthritis (OA) of the knee affects the aging population and has an influence on the health care system. Rigorous studies evaluating radiofrequency ablation for OA-related knee pain are lacking. This study compared long-term clinical safety and effectiveness of cooled radiofrequency ablation (CRFA); with intra-articular steroid (IAS) injection in managing OA-related knee pain.

The blood vessels

A new treatment for chronic pain from osteoarthritis has trialed following clinical research conducting; by the Royal Berkshire Hospital and the University of Reading. So the European first study injects tiny plastic beads the size of a grain of sand into the knee to block the blood vessels; that inflame the tissue and cause pain. Prior to the procedure, patients given an MRI scan of their brain and questionnaires to assess their pain threshold.

Richard Harrison, a researcher from the University of Reading’s School of Psychology and Clinical Language Sciences who is leading tests; “They understand that pain is one of the biggest barriers to successful outcomes following surgery. By using the latest scanning technology and psychological assessment; they hope to identify specific traits that predict the poor surgical outcome, and try and ultimately develop tools to improve outcomes.”

The Geniculate Artery Embolization

The procedure called geniculate artery embolization (GAE); involves positioning a plastic catheter tube into the abnormal knee blood vessels through a pinhole incision in the groin. X-rays are used to position the catheter into the arteries before the plastic beads are injected through it. “If the results of this study and a larger follow on study confirm the benefits of this treatment, then geniculate artery embolization is a potential game changer for the treatment of osteoarthritis.
Performed under only local anesthetic; the procedure takes about one hour, and patients go home the same day it is truly minimally invasive. “If you can get patients off high-dose painkillers who are struggling with mobility and unable to work; it has a massive impact on their health and quality of life.
In conclusion, This is a wonderful example of collaborative research between our academics with clinical partners and patients in our local NHS Trusts. This initiative is just one example of how, working together, we are making a real difference to people’s lives in the region and around the world.”
