Radiofrequency ablation is a minimally invasive procedure that uses heat generated by radio waves to disrupt the nerve signals causing chronic joint pain. It is most commonly used for facet joint pain in the spine and knee arthritis pain.
Radiofrequency ablation is considered for patients with chronic facet joint pain or knee arthritis pain who have had temporary relief from diagnostic nerve blocks. It is typically recommended after conservative treatments have been exhausted.
The procedure is performed under fluoroscopic or ultrasound guidance. A needle electrode is placed near the target nerve and heat is applied to interrupt pain signals. The procedure takes 30 to 60 minutes and is performed in an outpatient setting.
Risks include temporary soreness, numbness, skin burns, and infection. Serious complications are rare. Your physician will review all risks and confirm you are an appropriate candidate.
