How It Works
01
A numbing spray is applied to the skin before a small amount of local anesthetic is injected to further numb the area around the knee.
02
Using ultrasound to visualize the nerves of the knee, a small needle is placed next to the nerve.
03
The needle gets very cold without injecting anything into the body.
​
​
04
The extreme cold stops the nerve from sending pain signals to the brain without permanently destroying the nerve.
05
This process is repeated to cover all the nerves of the knee.
​
06
The pain relief is immediate, and can last up to 90 days.
