This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study tests two different minimally invasive procedures designed to reduce pain from knee arthritis. One procedure, called genicular artery embolization, uses tiny particles to reduce blood flow to the inflamed tissue around the knee joint. The other procedure, called genicular nerve phenol ablation, uses heat to quiet the nerves that carry pain signals from the knee. Researchers will compare how well each procedure works compared to a sham (fake) procedure to see which one helps patients feel better.
Knee arthritis can be very painful and disabling, but not all patients are ready for or suitable for knee replacement surgery. This medication addresses a real gap: there are no good head-to-head comparisons of these two newer, less invasive treatment options to help doctors and patients decide which might work best.

You will start with baseline tests including pain questionnaires, an MRI scan with contrast dye, and a small sample of fluid from your knee joint. You'll also receive a Fitbit tracker to monitor your activity. Then you'll be randomly assigned to receive one of the two procedures or a sham procedure, performed by a specialist doctor. After about 3 months, you'll return for follow-up assessments to measure how much your pain has improved. The study lasts approximately 24 months overall, with several follow-up visits to track your progress.
