Chronic knee pain can significantly impact daily life, limiting mobility and reducing overall quality of life. While knee osteoarthritis and joint degeneration are common causes, not every patient is a candidate for surgery. For those seeking alternatives to knee replacement, thermal denervation, also known as radiofrequency neurotomy, offers a promising solution. This minimally invasive procedure disrupts pain signals from the genicular nerves, helping to relieve discomfort and improve function.
What Is Radiofrequency Neurotomy?
Radiofrequency neurotomy (also called radiofrequency ablation) is a technique that uses controlled heat to target and disable the genicular nerves, which transmit pain signals from the knee to the brain. By interrupting these signals, the procedure provides long-lasting pain relief. It is particularly beneficial for individuals who:
- Have severe knee osteoarthritis but are not candidates for knee replacement surgery.
- Continue to experience knee pain despite previous surgeries.
- Prefer to avoid major surgery due to age or underlying health conditions.
The Procedure: What to Expect
Radiofrequency neurotomy is performed on an outpatient basis, meaning patients can return home the same day. The procedure involves:
- Fluoroscopic (X-ray) Guidance: The physician uses imaging to locate the genicular nerves surrounding the knee joint.
- Nerve Block Test: A small amount of local anesthetic is injected to temporarily numb the nerves. If this provides pain relief, the patient is considered a good candidate for radiofrequency neurotomy.
- Heat Application: A specialized needle delivers radiofrequency energy to the targeted nerves, disrupting their ability to send pain signals.
The entire process typically takes 30 to 45 minutes, and most patients experience minimal discomfort during the procedure.
Recovery and Expected Results
Following the procedure, some patients may experience temporary numbness, tingling, or soreness at the injection site. However, these effects usually resolve within a few days. The benefits of radiofrequency neurotomy can last anywhere from 6 months to 2 years, depending on the individual.
Many patients report significant pain reduction, allowing them to return to everyday activities with greater ease. If pain recurs, the procedure can be safely repeated.
How Effective Is Radiofrequency Neurotomy?
Studies have shown that radiofrequency neurotomy can provide better pain relief than traditional corticosteroid injections for knee osteoarthritis. Research published in the International Journal of Rheumatic Diseases suggests that this treatment effectively reduces pain and improves knee function.
Key benefits include:
- Reduced knee pain and stiffness
- Improved mobility and function
- Minimal downtime compared to surgery
- No need for prolonged rehabilitation
Is Thermal Denervation Right for You?
This procedure is best suited for individuals who:
- Have chronic knee pain that has not responded to other treatments.
- Are not ready for or eligible for knee replacement surgery.
- Want a non-surgical and minimally invasive pain relief option.
Before undergoing treatment, patients should consult a pain management specialist to discuss their medical history, symptoms, and treatment goals.
Conclusion
Thermal denervation, or radiofrequency neurotomy, is a safe and effective option for managing chronic knee pain. By targeting the genicular nerves, this procedure helps patients regain mobility and improve their quality of life without the risks associated with major surgery. If you are struggling with persistent knee pain, consider discussing radiofrequency neurotomy with your doctor to determine if it is the right solution for you.
