Genicular Nerve Ablation (RF Neurotomy)
During this outpatient procedure, the physician
uses a radiofrequency device to heat up and disrupt
the genicular nerves. These are the sensory nerves
that transmit pain signals from the knee to the
brain. Disrupting these pathways can provide long
term relief from knee pain.
In preparation for the procedure, the patient may be
given an IV and a mild sedative to help relaxation.
The skin of the knee is cleansed and sanitized. The
physician numbs the skin with local anesthetic.
Using a fluoroscope (a type of x-ray device that
shows video images from within the body), the
physician carefully guides a needle through the skin
and down to the target nerve. A thin electrode is
passed through this needle. When the electrode is
activated, it heats up the nerve. This heating
process, called ablation, is not painful. It will
eliminate the nerve's ability to transmit pain signals.
The ablation process is repeated at two more
locations to treat three of the genicular nerves.
End of Procedure
When the procedure is complete, the knee is
bandaged. The patient is monitored for a short time
before being released. The leg may feel numb for a
short time after the procedure until the anesthetic
wears off. Pain relief should begin immediately, and
may last for several months.
