Genicular Neurotomy
"Genicular neurotomy or genicular radiofrequency ablation is a procedure to relieve knee pain from osteoarthritis by treating the genicular nerves in the knee with radiofrequency waves to prevent transmission of pain signals to the brain. Genicular neurotomy is indicated for chronic knee pain when conservative treatments such as medication, physical therapy or steroid injections does not provide sufficient pain relief. Those who cannot undergo surgery for various reasons will also benefit from this procedure. It can also relieve knee pain that persists after surgery and may be used before or after knee replacement surgery to speed up recovery."
