Intra-articular Corticosteroid Injection in GAE for Knee Knee Osteoarthritis

Participants will undergo geniculate artery embolization (GAE) followed by an intraoperative intra-articular corticosteroid injection (IACI). This combination aims to alleviate post-procedural pain and improve early functional outcomes in patients with knee osteoarthritis (OA).

Participants will undergo geniculate artery embolization (GAE) without the additional intraoperative intra-articular corticosteroid injection. This procedure aims to serve as a control to evaluate the effectiveness and safety of GAE with IACI in comparison.
