- ≥80% relief with diagnostic genicular nerve blocks
- Willingness to undergo fluoroscopy-guided genicular nerve RFA treatment.
You may not qualify if:
- Conditions that preclude RFA (e.g. pregnancy, pacemaker/ICD, severe cardiac/pulmonary compromise; acute illness/infection; coagulopathy or bleeding disorder; allergic reactions/contraindications to a local anesthetic.
