Knee pain improvement after genicular artery embolization for the management of knee osteoarthritis: an updated systematic review and meta-analysis of 21 studies.

Background: Knee osteoarthritis is a progressive inflammatory musculoskeletal disease with a prevalence of approximately 15-23% and limited treatment options. In recent years, transcatheter genicular artery embolization (GAE) has been proposed due to promising results concerning symptomatic knee pain relief and mobility.

Objective: This systematic review and meta-analysis aimed to evaluate the aggregated data on the safety and efficacy of GAE for pain reduction in the treatment of knee osteoarthritis.
