Please note: This trial has finished recruiting and is not accepting new participants.

Research Center: University of Kansas Medical Center
Location: 3901 Rainbow Blvd Kansas City, KS 66160
Lead Doctor: Dr. Neil Segal
IRB Committee: This study has been reviewed and approved by the University of Kansas Medical Center (KUMC) Institutional Review Board


Cryoneurolysis, aka cryoanalgesia, is a minor procedure similar to the use of cold temperatures to numb the skin. It temporarily blocks nerve conduction to reduce or halt pain. By cooling down the nerve, it is temporarily unable to send signals of pain to the brain, and can provide pain relief.

This study is exploring the use of cryoneurolysis in people experiencing painful ankle osteoarthritis. It aims to find out if the procedure can help avoid surgical intervention but also provide immediate relief from pain for a longer duration.

This study seeks men and women who currently suffer from ankle osteoarthritis. Participants must be experiencing pain in one ankle for at least 15 days in the past month but are able to walk without any assistance.
