If you suffer knee pain, whether from arthritis, an injury or a degenerative joint disease, avoiding a knee replacement is desirable. Before opting to undergo a knee replacement, however, you might consider finding pain relief from a genicular nerve block.
The genicular nerve block is a diagnostic procedure which determines whether the changes and inflammation within your knee joint are the actual source of your knee pain. The genicular nerve block will also confirm that your pain will respond to the procedure. If the procedure works, you will experience pain relief for several hours, then your pain will return. The genicular nerve block is usually performed twice, and if both tests are positive, you will be scheduled for a treatment known as radiofrequency ablation or genicular nerve ablation. The genicular nerve ablation is expected to restore function to your knee, as well as alleviating your chronic knee pain.
Severe knee pain is a common complaint in people suffering from progressive diseases like osteoarthritis. Pain is also common following a failed knee surgery like partial or total knee replacement.
For many people, chronic knee pain can be treated by blocking pain signals that are fed into the knee through the genicular nerves. This procedure is called Genicular Nerve Block or Neurotomy. Genicular nerve block/neurotomy is a relatively new technique used to treat severe knee pain that has not responded to other treatments. There are typically 3 branches targeted with genicular nerve block – the superior medial branch, the superior lateral branch, and the interior medial genicular nerves.
What to expect after procedure:
You may notice some swelling or pain around the injection site, but should also notice that your typical knee pain is substantially less. The effects of the nerve block can last from a few hours to a few days. We tell most patients to take it easy the rest of the day, but you may return to normal activities as soon as you feel ready. If the nerve block is successful and your knee pain is substantially reduced, you are able to use less pain medication and you find yourself able to do more activity with less pain, then the nerve block is successful. Once you have successful nerve block your doctor will schedule you for the neurotomy (nerve deadening). This is a very similar procedure as above expect rather than numbing and blocking the nerve, the doctor will deaden the nerve with a special needle. This relief may last anywhere from 6 months to two years.
Which Conditions Can Be Treated Using Genicular Nerve Block?
Conditions commonly treated with genicular nerve blocks:
- Knee Osteoarthritis - This type of arthritis is due to wear and tear on the knee joint
- Chronic knee pain - Chronic knee pain can be caused by tendinitis, injury, osteoarthritis, gout, or other conditions
- Degenerative Joint Disease Patients with pain after total or partial knee surgery
- Patients with chronic knee pain who are not surgical candidates
What To Expect From Your Procedure ?
Arrive 20 minutes prior to your appointment on procedure day. If you request sedation, our Doctors will start an IV. They will also perform a preoperative assessment. Following your assessment, you will be taken to your procedure room where you will receive sedation to make you more comfortable.
A cleaning solution will be placed on your skin to help decrease chances of infection. The procedure site is then identified by your doctor under x-ray guidance. Once the site is identified, a shot of numbing medicine will be given to numb the skin. The shot may initially feel like a bee sting, but the sensation will last only a few seconds.
The spinal needle is then placed into the position using x-ray guidance. Medication and local anesthetics is injected through the needle. This medication disperses and bathes the nerves. Most patients report some pain relief almost immediately. The needle is then removed and you will be taken to the recovery room. The procedure itself takes 10-15 minutes. You will be observed for an additional 15 minutes after the procedure is complete.
What To Expect After Your Procedure ?
You may notice mild swelling or pain at the injection site following your nerve block procedure. However, you should also notice a substantial decrease in typical knee pain. Pain relief usually lasts from a few hours to a few days.
A successful genicular nerve block will lessen your pain enough that you don’t require as much pain medication during the day. You will also experience less pain while performing normal activities.
After a successful nerve block,Our pain doctor will schedule a neurotomy (nerve deadening) or radiofrequency ablation procedure.
The process for genicular nerve neurotomy is similar to a nerve block. However, instead of numbing and blocking the nerve, our doctor will deaden it with a special needle. Pain relief from neurotomy lasts longer .
