Neurolysis for the Treatment of Medial Chronic Knee Pain Due to Osteoarthritis

Summary

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.

Eligibility

13. Inability to attend follow-up visits and physiotherapy due to travel distance or other restrictions
14. Symptomatic multifocal nociplastic chronic pain (e.g., fibromyalgia, generalized osteoarthritis) or any other chronic pain condition that could influence symptoms.
15. Participants who have undergone radiofrequency ablation of the genicular nerves in the planned treatment limb within the preceding 6 months.
