The genicular nerve is a major nerve in the knee that can become painful as a result of osteoarthritis. When other non-invasive pain relief options like pain relievers, physical therapy, or steroid injections provide dismal relief or no relief at all, genicular radiofrequency ablation (RFA) may be an option. Learn more about genicular radiofrequency nerve ablation offered by Midsouth Spine & Pain Associates (MSSP) and how this procedure may help provide relief from chronic knee pain. 

What is genicular radiofrequency ablation?

The webbing of nerves surrounding the knee from the front to the backside is known as the genicular nerves. Knee injuries or those that suffer from osteoarthritis may experience chronic knee pain that is not well controlled with over-the-counter pain relievers and physical therapy. When this is the case, genicular radiofrequency ablation may be recommended. Using radiofrequency waves or a current that produces heat to destroy a small section of the genicular nerve relieves pain by preventing the nerves from sending pain signals to the brain. With reduced pain levels, you will be able to regain mobility and lessen the need for pain medication.

The Procedure

Genicular RFA takes approximately 15-30 minutes per knee and results in minimal downtime and recovery. The procedure begins by numbing the treatment area, which may result in a burning feeling at first. You remain awake during genicular RFA treatment since the procedure is administered under local anesthetic. Then, our pain management physician inserts a tiny hallow needle with an electrode attached that sends radiofrequency currents to the targeted area. The heat generated by the needle creates lesions on the genicular nerve, although surrounding tissue is not affected.

Before Your Procedure

A thorough review of your health history and your knee will be conducted by our pain management specialist near Jackson to determine if genicular RFA is the best pain-relieving treatment for you. To ensure that the genicular nerve is in fact the problem, the doctor may administer a genicular nerve block to see how you respond. If your pain diminishes and you experience good results from the nerve block, then genicular RFA will be recommended. However, if you do not respond well to the genicular nerve block, other treatments may be recommended.

After Your Procedure

Recovering from genicular RFA requires little downtime. However, you should have someone drive you home following your procedure because your knee will be numb afterward for a few hours. Plan on resting for the remainder of the day and avoid any strenuous activity for the first 24 hours. Soreness or tenderness are common at the treatment site, although applying ice packs for up to 20 minutes at a time can help relieve any discomfort. Expect to experience full pain-relieving effects within a week to three weeks following treatment. Results may last up to six months or longer.

Risks and Complications

Risks and complications associated with genicular RFA are rare, although permanent nerve damage may occur. Additionally, infection or bleeding may occur, although rare, and it is possible to feel burning or numbing sensations for several weeks following treatment. If you experience any redness, swelling, or unusual weakness in your treated knee, consult with your Tupelo pain management team immediately.
