The Canary Health authority has decided against adopting the genicular artery embolization (GAE) technique, an intervention that promised to improve the quality of life for patients with knee osteoarthritis by reducing inflammation and pain. A feasibility study conducted by the Canary Health Service concluded that the evidence of its effectiveness is insufficient to justify its implementation in the archipelago's healthcare facilities.
Knee osteoarthritis affects a significant portion of the population over 60 years old (35.8%) and also younger adults (10.2% over 20), causing persistent inflammation, stiffness, and pain that limits mobility and quality of life. Current treatments include medication, mobility exercises, and surgical interventions, but their effectiveness varies.
GAE involves introducing gelatin microspheres or other absorbable compounds into the abnormal blood vessels around the knee to block blood flow and reduce inflammation. This technique was presented as an attractive alternative for patients who do not respond to pharmacological treatments or wish to avoid joint replacement surgery.
However, the studies analyzed by the Canary Health Service showed mixed results. Some patients reported no improvement, while others perceived only mild or moderate relief. Given this variability and the lack of conclusive evidence, Canary Health considers the effectiveness of GAE to be limited and not cost-justified.
For the time being, healthcare professionals in the Canary Islands will continue to use the already approved treatment methods, which include rehabilitation, medication, and, in severe cases, joint replacement surgery.
