Mine was done early April 2018 so it's close to a year. Ran into one of my OT therapists last night and she confirmed that since I have had trouble since the beginning, she wasn't surprised. Was told my thumb will be a little shorter now. Also, every article I have seen written by surgeons all have a disclaimer at the end. "If the implant doesn't work they can always take it out and do the other procedure with little damage."
