What this trial is about
This clinical study investigates a minimally invasive treatment called percutaneous transcatheter embolization of knee arteries for patients with chronic knee pain caused by advanced knee osteoarthritis or persistent pain after total knee replacement. Osteoarthritis of the knee is a common degenerative condition that can lead to long-term pain, reduced mobility, and decreased quality of life, and some patients do not achieve sufficient relief with standard treatments. The study is based on the hypothesis that targeted embolization of small arteries supplying the inflamed tissues of the knee can safely reduce abnormal blood flow associated with inflammation, leading to pain relief and improved knee function. During the procedure, a thin catheter is guided through the blood vessels to the affected area of the knee, where a temporary embolic agent is administered to reduce pathological blood supply. The aim of the study is to evaluate the safety and effectiveness of this procedure by assessing changes in pain intensity, knee function, and quality of life over a follow-up period of up to 24 months. The results of this study may help determine whether this minimally invasive approach can offer a new treatment option for patients who have limited alternatives for managing chronic knee pain
