RADIOFREQUENCY ABLATION
Knee pain can be managed in various ways, and does not necessarily require major surgery or medications.
Radiofrequency ablation is a non-surgical procedure that involves the insertion of a needle-like probe into the skin. This probe delivers radiofrequency waves to target the nerves supplying the knee (genicular nerves) that are causing your pain. It may work for some patients to improve their symptoms
BENEFITS
Radiofrequency ablation is a safe and effective procedure with minimal recovery time. The results can be long-lasting (up to or greater than 12 months). RFA is especially beneficial to those seeking an alternative to surgery.
Minimally Invasive
Unlike surgery RFA involves no long incisions – just 3 needle-like probes are applied whilst you are under sedation. The procedure is completed in approximately 20 minutes, with sedation administered to the patient through an IV catheter. You may experience some discomfort at the radiofrequency site for a short period, but this discomfort can be treated with common over-the-counter medication.
Safe
RFA is considered a low-risk procedure. While some complications have been reported, most are temporary and can be resolved with little to no medical intervention. The most common side effects include hypersensitivity, numbness, burning, and tingling at the injection site.
Long-lasting results
Current studies are demonstrating up to 12 months pain relief and functional improvement specifically for knee pain and osteoarthritis.
When will I begin to feel pain relief?
You should begin to feel pain relief within one to two weeks. In some patients, the relief can be relatively long-lasting. In others, additional treatments may be required.
When can I return to normal activities?
Recommended rest will vary based on your unique needs. You can generally return to work and normal everyday activities within several days.

PROCEDURE
POST PROCEDURE
ANAESTHESIA
You will be sedated for the procedure (a full general anaesthaetic is generally not required) and local anaesthaetic will also be applied to the probe sites to minimise procedural and post-procedural discomfort.
PROCEDURE
An intravenous (IV) catheter is placed into the patient’s arm before the procedure, through which the anaesthetic is administered. Some patients will also receive a mild sedative. Xray imaging technology is then used to identify the knee joint and affected area, the doctor will then insert a hollow needle into the area. A microelectrode placed inside the needle will transmit a pulsed radiofrequency current into the target cells. Afterwards, the electrode and needle are removed, and pressure is applied to the insertion point. The skin is covered with a dressing.
POST PROCEDURE
After the procedure, the patient will receive post-procedural instructions. Most patients will be able to go home on the day of the procedure, but driving and strenuous activity should be avoided for 24 hours. Rest should be prioritised in the first 48-72 hours following RFA, and pain relief and icing can be used to resolve any post-procedural discomfort or pain.
SURGICAL RISKS
Radiofrequency ablation is considered a safe, low-risk procedure. Like all procedures, it is associated with risks, which can include swelling, bruising, minor pain, and hypersensitivity of the skin at the injection site.
Serious complications are rare, but can include:
- Infection of the injection site
- Damage to surrounding blood vessels and nerves, resulting in bleeding and nerve damage
- Damage to surrounding muscle tissue
- Allergic reaction to the anaesthetic used to numb the skin
RECOVERY AND EXERCISES
In the first few days following RFA, an ice pack may be used to numb the injection area and reduce swelling.It is best not to submerge the area in water, so showers are recommended over baths.
Pain relief can be used for 1-3 weeks after the procedure. Full recovery may take up to four weeks.

Pain is a common side effect of radiofrequency ablation, both during the procedure and in the following 1-2 weeks. Most patients describe this pain as mild, and are able to gain relief with a combination of over-the-counter medication and icing.
Radiofrequency ablation has few associated risks, but may include numbness, swelling, bruising, and/or hypersensitivity at the injection site. These symptoms may last for up to two weeks post-procedure.
RFA will be performed by your orthopedic specialist and supported by their nursing team.
