Overview
Brief Summary
This multicenter, prospective, interventional trial is designed to assess the outcome of subjects with symptomatic knee osteoarthritis (OA) that are randomized to treatment with either genicular artery embolization (GAE) using Embosphere Microspheres or steroid injection over a period of 24 months.
Detailed Description
This study is an IDE study. It is an RCT comparing GAE to steroid injection in the knee to treat knee osteoarthritis.
