Procedure Description
Radiofrequency ablation (RFA) is a minimally invasive procedure used to provide long-term pain relief by disrupting nerve signals that transmit pain from a damaged or arthritic joint. RFA uses heat generated by radio waves to ablate (deactivate) the small sensory nerves that innervate the joint—without affecting movement or strength.
This procedure is commonly used for the shoulder, hip, and knee joints when other conservative treatments (such as injections, medications, or physical therapy) have failed to provide adequate relief. It is often performed after a successful diagnostic nerve block, confirming the nerves as the source of pain.
What It Treats
RFA is effective for managing chronic pain in:
Shoulder joint arthritis or degenerative joint disease
Hip joint osteoarthritis
Knee osteoarthritis or post-surgical knee pain
Pain after joint replacement surgery, when structural issues have been ruled out
Patients who are not ready for, or wish to avoid, joint replacement surgery
RFA targets sensory nerves such as:
Shoulder: Suprascapular, axillary, and lateral pectoral nerves
Hip: Articular branches from the femoral and obturator nerves
Knee: Genicular nerves (superior medial, superior lateral, and inferior medial)
How It Is Performed
You will lie comfortably on a procedure table, depending on the joint treated.
The skin is cleansed and numbed with local anesthetic.
Using fluoroscopic (X-ray) or ultrasound guidance, a thin probe is placed near the sensory nerves supplying the joint.
A small electrical current is used to test nerve location, ensuring no motor nerves are involved.
Once confirmed, radiofrequency energy is applied to heat and deactivate the target nerves.
The probe is removed, and a small bandage is placed.
The procedure typically takes 30–45 minutes, depending on the joint, and is performed in an outpatient setting.
Pre-Procedure Instructions
Do not eat or drink for at least 6 hours prior to the procedure if sedation is planned.
Review medications with your provider—blood thinners may need to be paused.
Inform your provider if you:
Are pregnant or breastfeeding
Have allergies to anesthetics, contrast dye, or antiseptics
Have an active infection or illness
Arrange for a ride home if you receive sedation.
Wear loose, comfortable clothing that allows access to the treatment area.
What to Expect After the Procedure
Mild soreness or swelling at the injection site is common and usually resolves within a few days.
Pain relief often begins within 1–2 weeks and may last 6–12 months or longer.
You may return to light activity the same day, but avoid strenuous activity for 24–48 hours.
Physical therapy may be recommended to improve joint function and extend the benefits of treatment.
If the pain returns over time, the procedure can be safely repeated.
Call your provider if you experience:
Fever or chills
Persistent or severe pain
Numbness, weakness, or signs of infection at the treatment site
