Program Genicular Nerve Radiofrequency Ablation (RFA)

If knee pain is affecting your quality of life, and you’ve found temporary relief from a genicular nerve block, a genicular nerve radiofrequency ablation (RFA) may be the next step in your treatment plan for lasting pain relief.

What is Genicular Nerve Radiofrequency Ablation (RFA)?

Genicular nerve RFA is a minimally invasive procedure that targets the genicular nerves responsible for transmitting pain signals from the knee joint. During RFA, heat is applied to these nerves, effectively disrupting their ability to send pain signals. This provides long-term relief from knee pain, particularly for conditions like osteoarthritis or knee injuries.

Who Can Benefit from Genicular Nerve RFA?

If you have chronic knee pain, especially after experiencing temporary relief from a genicular nerve block, genicular nerve RFA may be a good option for you. It’s particularly beneficial for those suffering from knee pain due to osteoarthritis, trauma, or previous surgeries that haven’t responded to medications or physical therapy.

What to Expect During the Procedure?

• The procedure typically takes 30 to 45 minutes. Local anesthetic will be applied to minimize discomfort. Sedation is optional based on your comfort level.
• The doctor uses ultrasound guidance to accurately target the genicular nerves, then applies heat through a needle-like probe to disrupt the nerves. 
• You may experience mild discomfort during the procedure, but it is generally well tolerated.

What Results Can I Expect?

After the procedure, you can expect a significant reduction in knee pain. The effects of RFA can last up to 3-6 months, depending on individual response. You may find that you can reduce or eliminate your reliance on pain medications, improving your overall quality of life.

What Should I Do After the Procedure?

Genicular nerve RFA offers a long-term solution for knee pain without the need for continuous pain medication or surgery. It’s a safe and effective way to manage knee pain and improve your mobility, especially if conservative treatments like physical therapy or injections have not provided lasting relief.
