Genicular Radiofrequency Ablation (RFA) for Chronic Knee Pain

Genicular radiofrequency ablation (RFA) is a minimally invasive procedure used to treat chronic knee pain, especially when other treatments have not provided enough relief.

This procedure targets the genicular nerves, which carry pain signals from the knee joint to the brain. Using controlled heat (radiofrequency energy), these nerves are temporarily deactivated, reducing pain signals and improving function.

Genicular RFA is often recommended for patients with knee arthritis or persistent knee pain who want to avoid or delay surgery.

What Conditions Does This Treatment Help?

Genicular RFA is commonly used to treat:

Knee osteoarthritis (most common use)
Chronic knee pain after injury
Persistent pain after knee replacement surgery
Degenerative joint disease of the knee
Knee pain not relieved by medications or injections

How Does Genicular RFA Work?

Chronic knee pain is often caused by irritation of the nerves around the joint.

The genicular nerves transmit pain signals from the knee
A small needle is placed near these nerves using imaging guidance
Radiofrequency energy heats and disrupts the nerve’s ability to send pain signals
This leads to reduced pain and improved movement

Because the nerves can regenerate over time, the procedure may be repeated if needed.

What to Expect During the Procedure

Before the Procedure

A diagnostic nerve block is performed first to confirm the source of pain
If significant temporary relief is achieved, RFA may be recommended

During the Procedure

Performed under local anesthesia with or without sedation
Needles are placed around the knee using X-ray guidance
Radiofrequency energy is applied to targeted nerves
Procedure typically takes 20–30 minutes

After the Procedure

Same-day discharge
Mild soreness at treatment site
Most patients resume normal activities quickly

Benefits of Genicular Radiofrequency Ablation

✔ Minimally invasive, no surgery required
✔ Effective for chronic knee pain
✔ Improves mobility and daily function
✔ Reduces need for medications
✔ Can delay or avoid knee replacement

Studies show many patients experience significant pain reduction and improved quality of life after the procedure.

Who Is a Good Candidate?

You may be a candidate if you:

Have chronic knee pain lasting 6 months or more
Have knee osteoarthritis or degenerative joint disease
Have not improved with medications, physical therapy, or injections
Are not ready for or want to avoid surgery
Experienced relief from a diagnostic nerve block

This procedure is ideal for patients seeking a non-surgical pain management option.

Risks & Side Effects

Genicular RFA is generally safe, but possible risks include:

Temporary soreness or swelling
Mild bruising
Temporary numbness
Infection or bleeding (rare)

Serious complications are uncommon when performed by experienced providers.

When Is This Treatment Recommended?

Genicular RFA is typically recommended when:

Conservative treatments have failed
Knee pain is chronic and limiting daily activities
Patients want to avoid or delay knee replacement surgery
Diagnostic nerve block confirms nerve-related pain

👉 It is positioned as a step after injections but before surgery

Recovery & Results

Mild soreness may last a few days
Pain relief typically begins within a few weeks
Relief usually lasts 6 to 12 months in many patients
The procedure can be repeated if pain returns

Many patients experience improved mobility and ability to stay active, which is key for long-term joint health.

FAQs

Is genicular RFA painful?

Most patients feel minimal discomfort during the procedure due to local anesthesia.

How long does the relief last?

Relief typically lasts 6–12 months, though results vary.

Will the nerves grow back?

Yes, nerves can regenerate over time, which is why repeat treatment may be needed.

Is this a permanent cure?

No, but it provides significant long-term pain relief and improved function.
