Genicular Nerve RFA For Knee Pain
Advanced Non-Surgical Treatment for Chronic Knee Pain
designed to provide long-lasting relief from chronic knee pain. The treatment targets the genicular nerves, which transmit pain signals from the knee joint to the brain. By interrupting these pain pathways using radiofrequency energy, significant pain reduction and improved mobility can be achieved without surgery.
This procedure is particularly beneficial for patients who have persistent knee pain despite medications, physiotherapy, or injections.
Indications
Genicular Nerve RFA may be recommended for:
- Knee Osteoarthritis
- Chronic Knee Pain
- Persistent Pain After Knee Replacement Surgery
- Degenerative Joint Disease
- Rheumatoid Arthritis Affecting the Knee
- Patients Unsuitable for Knee Replacement Surgery
- Patients Seeking to Delay Joint Replacement
- Chronic Pain Following Knee Injury
- Failed Conservative Management of Knee Pain
How Genicular Nerve RFA Works
The knee joint contains several sensory nerves known as genicular nerves that carry pain signals to the brain.
Radiofrequency Ablation uses controlled thermal energy to create a small lesion on these nerves, reducing their ability to transmit pain signals while preserving normal knee movement and function.
Before RFA is performed, diagnostic genicular nerve blocks are typically carried out to confirm that these nerves are the primary source of pain.
Procedure
The procedure is performed under fluoroscopic (X-ray) or ultrasound guidance to ensure accurate placement.
Diagnostic Genicular Nerve Block
Prior to RFA, local anesthetic is injected around the genicular nerves.
If significant temporary pain relief is achieved, the patient is considered a suitable candidate for Radiofrequency Ablation.
Radiofrequency Ablation Procedure
- The patient is positioned comfortably on the procedure table.
- Vital signs are monitored throughout the procedure.
- The skin around the knee is cleaned and sterilized.
- Local anesthetic is administered.
- Under image guidance, specialized RF needles are placed near the targeted genicular nerves.
- Sensory testing may be performed to confirm correct positioning.
- Radiofrequency energy is delivered for a controlled period to interrupt pain transmission.
Benefits
- Significant reduction in chronic knee pain
- Improved walking ability and mobility
- Better quality of life
- Reduced dependence on pain medications
- Minimally invasive procedure
- No surgical incision
- Rapid recovery
- Can delay the need for knee replacement surgery
- Long-lasting pain relief in appropriately selected patients
Special Instructions
Before the Procedure
- Inform your physician about all medications and medical conditions.
- Blood-thinning medications may require temporary adjustment.
- Follow fasting instructions if sedation is planned.
- Arrange transportation home after the procedure.
After the Procedure
- Rest for the remainder of the day.
- Avoid strenuous activities for 24–48 hours.
- Resume normal activities gradually as advised.
- Continue physiotherapy and strengthening exercises if recommended.
Recovery
Most patients return home on the same day.
Pain relief may begin within a few days but often reaches maximum benefit after 2–6 weeks as the treated nerves gradually stop transmitting pain signals.
The duration of relief varies between patients and may last from 6 months to 24 months or longer. If pain returns, the procedure can often be safely repeated.
Side Effects and Complications
Genicular Nerve RFA is generally considered a safe procedure with a low complication rate.
Common Temporary Effects
- Mild soreness at the needle insertion site
- Bruising
- Temporary swelling
- Mild discomfort around the knee
Rare Complications
- Infection
- Bleeding
- Allergic reaction to medications
- Temporary numbness
- Nerve irritation
- Skin sensitivity around the treatment area
