Genicular Nerve Radiofrequency Ablation (RFA)

Genicular Nerve Radiofrequency Ablation (RFA) is a minimally invasive procedure used to treat chronic knee pain by disrupting pain signals sent by the genicular nerves. The genicular nerves are small sensory nerves around the knee joint that can cause persistent pain, especially in cases of:

• Knee arthritis
• Post-surgical pain (even after knee replacement)
• Chronic knee pain not relieved by other treatments

The procedure uses radiofrequency energy to create a small heat lesion, which disables the targeted nerves and provides long-lasting pain relief without major surgery.

Your provider may recommend this procedure if you have:

• Chronic knee pain lasting more than 6 months
• Significant relief from a prior genicular nerve block (diagnostic injection)
• Pain limiting your mobility or daily activities
• Pain not responding to medications, physical therapy, or injections
• A desire to avoid or delay knee surgery or additional joint replacement procedures

RFA is an effective option to reduce knee pain and improve quality of life without needing more invasive operations.

• You will lie comfortably on an X-ray table.
• The skin around the knee will be cleaned and numbed with a local anesthetic.
• Using fluoroscopic (live X-ray) or ultrasound guidance, small needles are precisely placed near the genicular nerves.
• A special probe delivers radiofrequency energy to heat the nerve tissue, disrupting pain signals.
• Multiple nerves around the knee (usually 3–5 sites) are targeted during the procedure.
• Procedure time: About 30–45 minutes
• Sedation: Light sedation or local anesthetic is typically used for comfort.

• Mild soreness or bruising at the injection sites is normal and should resolve within a few days.
• Pain relief may begin within 1–3 weeks after the procedure as the nerves are deactivated and inflammation subsides.
• Most patients experience significant, lasting pain reduction for 6 months to over a year.
• You should avoid strenuous activities for 24–48 hours but can return to light activities shortly after.

Genicular nerve ablation is considered very safe. Rare risks include:

• Temporary increased knee soreness
• Bruising, swelling, or mild numbness at the treatment sites
• Infection (extremely rare)
• Nerve regeneration over time (leading to possible return of symptoms)
• Allergic reaction to numbing medication (rare)
