Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults over 50 with Kellgren-Lawrence grade 2 to 3 osteoarthritis and a VAS pain score exceeding 50mm.
✕Probably not a fit
Patients with infections, severe vascular disease, or those with a life expectancy of less than six months may not benefit from this study.

What this trial studies
This clinical trial evaluates the safety and effectiveness of Transcatheter Arterial Micro-Embolization (TAME) using Nexsphere-F in patients aged 50 and older with knee degenerative osteoarthritis. It targets individuals whose pain remains uncontrolled despite conventional treatments. The study is a single-arm, open-label pilot trial conducted at a single center, where participants will undergo TAME and have their pain assessed using various scoring systems before and after the procedure. Written consent is obtained prior to the procedure, and baseline evaluations include MRI and pain scoring.
Why it matters
Potential benefit: If successful, this treatment could provide significant pain relief for patients suffering from knee osteoarthritis who have not responded to standard therapies.
How similar studies have gone: While this approach is novel, similar studies exploring embolization techniques for pain management have shown promise, indicating potential for success.
