Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to learn if genicular artery embolization (GAE) can improve knee pain and decrease inflammation in adults with knee osteoarthritis. The main question it aims to answer is:

\- Does the GAE procedure improve knee pain and decrease inflammation?

Researchers will compare synovial fluid samples taken from the knee before and after the procedure.

Participants will:

* Have a contrast enhanced MRI before and after the procedure
* Complete performance-based measures before and after the procedure
* Complete questionnaires before and after the procedure
