Minimally Invasive Radiofrequency Treatment for Chronic Knee Pain
Chronic knee pain can make walking, climbing stairs, exercising, standing, and other everyday activities increasingly difficult. When conservative treatments do not provide adequate relief, genicular nerve ablation, also known as genicular radiofrequency ablation (RFA), may be considered for appropriately selected patients.
Genicular nerve ablation is a minimally invasive procedure that uses radiofrequency energy to target specific sensory nerves responsible for transmitting pain signals from the knee.
At TOPS Institute, we provide comprehensive evaluation and personalized treatment for chronic knee pain in Los Angeles and Beverly Hills. For appropriate candidates, genicular nerve radiofrequency ablation may provide longer-lasting pain relief without major knee surgery.

What Is Genicular Nerve Ablation?
Genicular nerve ablation is a minimally invasive procedure that uses radiofrequency energy to reduce pain signals traveling from the knee to the brain.
The knee receives sensory information from several nerve branches known as the genicular nerves.
These nerves help transmit pain signals from structures surrounding the knee joint. During genicular nerve ablation, selected nerve branches are targeted with controlled radiofrequency energy.
The procedure is designed to interrupt or reduce transmission of pain signals while preserving the primary motor nerves responsible for movement.
Genicular nerve ablation does not replace or reconstruct damaged cartilage or other structures within the knee. Instead, it targets the nerves carrying pain signals from the affected area.
What Is Genicular Radiofrequency Ablation?
Genicular radiofrequency ablation (RFA) is another name commonly used for genicular nerve ablation.
Radiofrequency ablation uses controlled thermal energy generated by radiofrequency waves to create a targeted lesion along selected sensory nerve branches.
By disrupting the ability of these nerves to transmit pain signals, the procedure may provide meaningful pain relief for appropriately selected patients.
The goal is to reduce chronic knee pain so patients can improve mobility, participate more comfortably in rehabilitation, and perform everyday activities with less discomfort.
What Conditions Can Genicular Nerve Ablation Treat?
Genicular nerve ablation may be considered for selected patients with persistent knee pain that has not responded adequately to more conservative treatments.
Potential candidates may include patients with:
- Chronic knee pain
- Knee osteoarthritis
- Degenerative knee joint pain
- Persistent knee pain despite conservative treatment
- Persistent pain following knee replacement in selected circumstances
- Knee pain that significantly limits mobility and daily activities
Not every type of knee pain originates from structures supplied by the targeted genicular nerves.
A comprehensive evaluation is therefore important before determining whether genicular nerve ablation is appropriate.

Genicular Nerve Ablation for Knee Osteoarthritis
Knee osteoarthritis is a common cause of chronic knee pain, particularly as people age.
Osteoarthritis develops as cartilage and other structures within the knee joint undergo degenerative changes. Patients may experience:
- Aching knee pain
- Stiffness
- Swelling
- Reduced range of motion
- Pain when walking
- Difficulty climbing stairs
- Pain when standing from a seated position
- Reduced ability to exercise
Genicular nerve ablation does not reverse osteoarthritis or regenerate damaged cartilage.
Instead, it may be considered as a pain-management option for selected patients when osteoarthritis-related knee pain remains significant despite conservative care.
Who May Be a Candidate for Genicular Nerve Ablation?
Genicular nerve RFA may be considered when chronic knee pain continues despite appropriate nonsurgical treatment.
Potential candidates may include patients who:
- Have persistent chronic knee pain
- Have knee osteoarthritis or degenerative joint pain
- Have not experienced adequate relief from conservative treatment
- Have difficulty walking or performing everyday activities because of pain
- Are not ready for or are not appropriate candidates for knee replacement surgery
- Continue to experience selected types of knee pain after knee surgery
- Experience meaningful temporary relief from a diagnostic genicular nerve block
The decision to proceed with radiofrequency ablation is individualized based on the patient’s diagnosis, examination, previous treatment, and response to diagnostic testing.
What Is a Genicular Nerve Block?
Before genicular nerve ablation, a diagnostic genicular nerve block may be performed to determine whether the targeted nerves are contributing to the patient’s knee pain.
During the procedure, a small amount of local anesthetic is placed near selected genicular nerves.
The patient’s pain response is then evaluated during the expected period of anesthetic effect.
If the patient experiences meaningful temporary relief, this provides evidence that the targeted nerves are transmitting a significant portion of the knee pain and may help determine whether radiofrequency ablation is appropriate.
The relief from a diagnostic block is expected to be temporary. Its primary purpose is to provide diagnostic information.
How Does Genicular Nerve Ablation Work?
Genicular nerve ablation targets sensory nerve branches around the knee that transmit pain signals.
During the procedure:
- The targeted genicular nerves are identified using image guidance.
- Specialized radiofrequency needles are positioned near the appropriate nerve branches.
- The position is carefully evaluated before treatment.
- Controlled radiofrequency energy is delivered to the targeted area.
- The resulting lesion reduces the nerve’s ability to transmit pain signals.
The procedure does not remove the nerve or alter the structural cause of knee arthritis.
Instead, it changes how pain signals from the knee are transmitted.
What Are the Benefits of Genicular Nerve Ablation?
For appropriately selected patients, potential benefits may include:
- Reduced chronic knee pain
- Improved walking tolerance
- Greater ability to perform everyday activities
- Improved participation in physical therapy or exercise
- Reduced reliance on some pain-management strategies
- Minimally invasive treatment
- Avoidance or delay of more invasive treatment in selected patients
Results vary between patients, and pain relief cannot be guaranteed.
The goal is meaningful improvement in pain and function rather than elimination of every sensation from the knee.
How Long Does Genicular Nerve Ablation Last?
Pain relief following genicular radiofrequency ablation varies from person to person.
Radiofrequency ablation disrupts the targeted sensory nerves, but peripheral nerves can regenerate over time. As nerve function returns, knee pain may eventually recur.
Some patients may experience relief lasting several months or longer, while others may experience a shorter or less significant response.
The duration of benefit depends on the individual patient, underlying knee condition, and other clinical factors.
Can Genicular Nerves Grow Back?
Yes. The targeted nerve branches can regenerate over time.
Genicular nerve ablation is therefore not necessarily a permanent treatment.
If the nerves regenerate and begin transmitting pain again, symptoms may return. In appropriately selected patients who previously experienced meaningful relief, repeat radiofrequency ablation may sometimes be considered after reevaluation.
Genicular Nerve Ablation vs. Knee Injections
Genicular nerve ablation and knee joint injections treat chronic knee pain in different ways.
Joint injections deliver medication or other substances into the knee joint and may be used to address inflammation or other joint-related symptoms.
Genicular nerve ablation targets sensory nerves outside the joint that transmit pain signals.
Depending on the patient’s diagnosis and goals, treatment options at TOPS Institute may include:

The appropriate treatment depends on the source of pain, severity of joint degeneration, previous treatment, and individual clinical circumstances.
Does Genicular Nerve Ablation Replace Knee Surgery?
Genicular nerve ablation is not a replacement for knee surgery in every patient.
The procedure does not repair structural damage or replace an arthritic knee joint.
However, it may provide a nonsurgical pain-management option for selected patients who:
- Want to continue nonsurgical treatment
- Are not appropriate surgical candidates
- Prefer to delay surgery when medically appropriate
- Continue to experience certain types of chronic knee pain despite previous treatment
Patients with advanced structural problems may still require orthopedic evaluation.
What Is Recovery Like After Genicular Nerve Ablation?
Genicular nerve ablation is typically performed as an outpatient procedure.
Patients may experience temporary soreness or discomfort around the treatment area following the procedure.
Specific post-procedure instructions depend on the patient’s condition and procedure performed. Patients should follow their provider’s recommendations regarding activity, exercise, medications, and return to normal activities.
Improvement may not always occur immediately because the treated nerves require time to respond to radiofrequency ablation.
Genicular Nerve Ablation at TOPS Institute
Chronic knee pain can significantly affect independence, mobility, exercise, and quality of life.
At TOPS Institute, we take a diagnosis-driven approach to knee pain.
Rather than selecting treatment based on knee pain alone, we evaluate the underlying condition, previous treatments, functional limitations, and whether the genicular nerves appear to be contributing to the patient’s symptoms.
For appropriately selected patients, a diagnostic genicular nerve block can help determine whether genicular radiofrequency ablation may provide meaningful pain relief.
Our goal is to reduce chronic knee pain and help patients return to walking, exercise, work, and everyday activities with greater comfort.
For patients seeking genicular nerve ablation or radiofrequency ablation for knee pain in Los Angeles or Beverly Hills, TOPS Institute provides personalized interventional pain management based on each patient’s diagnosis and goals.

Frequently Asked Questions About Genicular Nerve Ablation
What is genicular nerve ablation?
Genicular nerve ablation is a minimally invasive treatment that uses radiofrequency energy to disrupt selected sensory nerves that transmit pain signals from the knee. It is also commonly called genicular radiofrequency ablation or genicular RFA.
Does genicular nerve ablation treat knee arthritis?
Genicular nerve ablation may help manage pain associated with knee osteoarthritis in appropriately selected patients, but it does not reverse arthritis or repair damaged cartilage. The treatment targets pain signals rather than the structural degeneration within the knee.
Do you need a nerve block before genicular nerve ablation?
A diagnostic genicular nerve block may be used before radiofrequency ablation to determine whether the targeted nerves are contributing to the patient’s knee pain. Meaningful temporary relief after the block can help guide the decision about whether to proceed with RFA.
How long does genicular nerve ablation last?
The duration of pain relief varies. Some patients experience relief for several months or longer, while others may have a shorter response. Because the targeted nerves can regenerate, pain may eventually return.
Do genicular nerves grow back after radiofrequency ablation?
Yes. Peripheral nerve branches can regenerate over time. If the targeted nerves regain function, knee pain may return. Repeat treatment may be considered for selected patients after reevaluation.
Is genicular nerve ablation painful?
Patients may experience temporary discomfort during or after the procedure, but local anesthetic is typically used to help minimize procedural discomfort. Your provider can explain what to expect based on the specific technique being used.
Can genicular nerve ablation help after knee replacement?
It may be considered in selected patients with persistent knee pain after knee replacement once appropriate evaluation has been performed and other causes of postoperative pain have been considered. It is not appropriate for every patient with pain after knee surgery.
What is the difference between genicular nerve ablation and a knee injection?
A knee joint injection delivers treatment into the joint itself. Genicular nerve ablation targets sensory nerve branches surrounding the knee that transmit pain signals. The appropriate treatment depends on the source and nature of the patient’s knee pain.
Can genicular nerve ablation prevent knee replacement?
Genicular nerve ablation does not repair structural joint damage and cannot guarantee that knee replacement will never be necessary. For selected patients, however, it may provide a nonsurgical option for managing chronic knee pain when surgery is not desired, appropriate, or immediately necessary.
