Overview
Knee pain can be chronic, debilitating, and can lead to loss of function. Genicular nerve blocks are indicated for those who have osteoarthritis (DJD), those who want to avoid knee replacement, those who have had knee replacement or any type of knee surgery, and those with chronic knee pain.
Genicular Nerve Blocks
The genicular nerves transmit pain impulses to the knee and surrounding structures. These nerves can be blocked by the injection of local anesthetic and with or without steroid under x-ray guidance.
Genicular Radio Frequency Ablation (RFA)
In cases where the genicular blocks provide good relief that did not last enough, radio frequency ablation may be performed to provide longer pain relief by stunning the nerves.
Frequently Asked Questions
How long do genicular nerve procedures take?
Injections are usually done at up to 3 sites at a time and can take 10 to 15 minutes. Radio frequency ablation may take roughly 30 minutes.
Is Radio frequency Ablation permanent?
Radio frequency ablation does not permanently destroy (or “burn”) the medial branch nerves. The nerves will slowly regenerate/grow back over time, which is why this procedure may need to be repeated.
How will I feel afterwards?
The majority of patients feel relief of their usual pain shortly after the procedure due to the injection of local anesthetic on the nerves. However, some patients will experience temporary muscle stiffness.
How long will the relief last?
Relief from injections is highly variable and can range from weeks to a month or two. Relief from RFA is more predictable and may last for a longer period of time.
