1.1 Evidence on the safety of genicular artery embolisation for pain from knee osteoarthritis shows no major safety concerns in the short term. Evidence on its efficacy and long-term safety is inadequate in quality and quantity. Therefore, this procedure should only be used in the context of research. Find out what only in research means on the NICE interventional procedures guidance page.
1.2 Research should preferably be randomised controlled trials against sham and current best practice. It should report details of patient selection and identify those who would most benefit from this procedure. It should also report details of the technique used, long-term safety, and patient-reported outcomes.
1.3 The procedure should only be done by interventional radiologists with specific training in this technique.
