Summary

This trial is testing whether a procedure to block abnormal blood vessels caused by knee arthritis is safe and effective in reducing knee pain.

Who is the study for?
This trial is for adults over 40 with moderate to severe knee pain due to osteoarthritis, who haven't found relief from anti-inflammatory meds, physical therapy, or injections. They should have certain MRI features of active synovitis and not be candidates for surgery. People with life-threatening allergies to iodine, recent major knee surgeries (except minor arthroscopic), serious coagulation issues, kidney problems or other types of arthritis are excluded.
What is being tested?
The trial tests the safety of genicular artery embolization (GAE) using HydroPearl® Microspheres in patients with osteoarthritic knee pain. GAE blocks abnormal blood vessels in the knee that contribute to arthritis pain. The study will follow participants for up to 24 months.
What are the potential side effects?
While specific side effects aren't listed here, similar procedures may cause discomfort at the injection site, bruising or bleeding complications due to arterial blockage; allergic reactions including anaphylaxis could occur in those sensitive to materials used.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Genicular artery embolizationExperimental Treatment1 Intervention
Participants will undergo the genicular artery embolization (GAE) procedure for the treatment of moderate to severe knee osteoarthritis. A total of 30 patients will be enrolled in the single treatment arm of the study. The study will involve a screening period in which patient eligibility is determined. Once eligibility is confirmed, patients will undergo GAE with HydroPearl® Microspheres (polyethylene glycol microspheres, Terumo Medical, Somerset NJ). Following treatment, patients will undergo follow-up at 1, 6, 12, and 24 months post GAE.
