What is a Genicular Nerve Radiofrequency Ablation?
A genicular nerve radiofrequency ablation (RFA) is a procedure in which a needle is placed near the genicular nerves in your knee and the needles are heated to destroy the sensory nerves that are responsible for sending pain signals into your brain. Radiofrequency ablations are a common procedure that can help to treat localized pain in knee(s) caused by osteoarthritis and other degenerative conditions.

Who is a candidate for Genicular Radiofrequency Ablation?
Patients who have a history of knee pain that has not responded to other treatments may be a candidate for a radiofrequency ablation. During your first consultation, your physician will review your medical history and perform a physical exam to determine if you may benefit from a genicular RFA. A genicular nerve block will be performed first, in which local numbing is injected around the genicular nerves as a diagnostic test. These diagnostic blocks are used to determine if your pain is being caused by your genicular nerves. Patients who experience relief from the genicular nerve blocks are considered to be good candidates for a genicular nerve RFA.
How is a Genicular Radiofrequency Ablation performed?
A genicular RFA is performed by targeting your medial branch nerves in your neck, mid-back or low back. Using fluoroscopic guidance (X-Ray) your physician will place a needle near your genicular nerve(s). Once the needle(s) are in the correct position a thermal lesion is created that destroys the sensory nerve. The procedure takes approximately 30 to 45 minutes and has little to no downtime. Patients may experience increased sensitivity in the area following the procedure and can expect to experience improvement around the 4 week mark. Patients who receive relief from a genicular RFA can have the procedure repeated every 6 months, if needed.

Genicular Nerve RFA FAQ
How long does pain relief last after a Genicular Nerve RFA?
Pain relief from a Genicular Nerve RFA can last from 6 – 12 months or longer, depending on individual factors and the progression of the underlying condition. In some cases, patients may experience significant relief for up to two years.
How soon can I return to normal activities after a Genicular Nerve RFA?
Most patients can resume normal activities within 24 – 48 hours after the procedure, although some may experience mild soreness at the injection sites. Our team at Ospina Medical recommends avoiding strenuous activities for a few days to allow the treatment area to heal.
Can Genicular Nerve RFA be repeated if necessary?
Yes, Genicular Nerve RFA can be repeated if pain relief diminishes over time. Since the genicular nerves can regenerate, a follow-up RFA procedure may be recommended after several months or years if the pain returns.
