Radiofrequency Ablation of Genicular Nerves of the Knee

Radiofrequency Ablation (RFA) is an innovative procedure that uses electrical currents to generate heat and destroy pain fibers in various areas, including facet joints, sacroiliac joints, or even the knee’s genicular nerves. Providing long-term relief, RFA is a more enduring solution than traditional blocks with local anesthetic or steroid injections.

General Pre-Injection Instructions

• Allergies: Notify our staff if you have allergies, especially to iodine.
• Fasting: Do NOT eat the morning of the procedure if sedation is required.
• Insulin Changes: Insulin-dependent diabetics receiving sedation may need to adjust insulin doses.
• Routine Medications: Continue taking high blood pressure and diabetic medications (e.g., Glucophage).
• Blood Thinners: If on Coumadin or similar medications, inform the staff for proper pre-procedure planning.
• Driving: Plan to have a driver accompany you home after the procedure.

What Happens During the Procedure?

1. Preparation: The patient is positioned for optimal access to the treatment area, and the skin is cleaned with antibacterial soap.
2. Local Anesthesia: A numbing agent is applied to a small skin area, causing brief stinging.
3. X-Ray Guidance: A small needle is guided using x-ray to the specific nerve to be treated.
4. Stimulation Test: The patient communicates sensations in the area to ensure proper needle positioning.
5. Nerve Confirmation: The nerve is tested to prevent unwanted muscle stimulation.
6. Ablation: The targeted area is numbed, and ablation is performed, followed by an injection of numbing medicine and steroid to minimize post-procedure pain (neuritis).

What Happens After the Procedure?

• Recovery Room: Patients are monitored in the recovery room after the procedure.
• Diet and Activity: No restrictions on food, liquids, or general activities, unless directed by the physician.
• Pain Increase: Temporary pain increase (2-3 days) is normal and doesn’t indicate a problem.
• Follow-Up: A follow-up appointment is scheduled to assess the response.
• Driving: Driving is discouraged on the day of the procedure.
