About this trial
This study involves the use of sound waves to block pain signals caused by osteoarthritis of the knee. The sound waves are tightly focused on a specific area of the nerve. The sound waves cause a break in the nerve which carries pain signals. Sound waves transmit through the skin so there is no need for needles. The procedure takes approximately one hour. The device has been approved in Health Canada and Europe for the treatment of lower back pain. This study is to evaluate the use of the same device for people in Canada who have knee pain related to osteoarthritis.
