Geniculate Artery Embolization for Knee Osteoarthritis
In Brief
A clinical study evaluating Gel-Bead embolization for Knee Osteoarthritis. Completed, enrolled 11 participants across 1 site.
Detailed Summary
The purpose of this study is to perform a prospective case series to determine efficacy of transcatheter arterial embolization in treating knee osteoarthritis related pain, improving functionality, and reducing opiate usage in patients with mild to moderate knee osteoarthritis who have failed conservative management. The Gel-Bead embolization particles will be used to perform geniculate artery embolization (GAE) for the purposes of treatment of osteoarthritis-related knee pain.
Study Details
Timeline
Interventions
OptiSphere is FDA approved for the embolization of hypervascular tumors. The product is crosslinked with glutaraldehyde, which improves the mechanical strength of the spheres and provides controlled degradation after implant. The spherical shape provides smooth embolic delivery and even, predictable distribution. In this study the Optispheres will be used for Geniculate artery embolization (GAE) which is a minimally-invasive procedure that has historically been performed for treatment of patients with recurrent knee hemarthrosis. Embolization is a procedure in which material is used to block small blood vessels. Angiogenesis, or growth of new vessels, has been implicated in the initiation and maintenance of joint inflammation. GAE has been applied to patients with moderate osteoarthritis-related pain refractory to maximal medical management with preliminary studies demonstrating a reduction in patient pain.
