I tried a device called "i-walk" took a while to get used to using it. It put a lot of stress on other body parts. I stopped using it when I had my TAR. Too risky to fall. plus I had to recover from the surgery. It would have caused too much swelling. Jery
I'm on day 2 from fusion and getting to grips with the I walk free 3, I had one of the original models 13 years ago when I last faced 12 weeks in plaster. I got very good at it and used it a lot for work, but it does taken practice & it's important to follow the you tube video instructions carefully. Now I'm older I will possibly have one crutch for balance in the opposite hand. Much easier than crutches for most but not all. 2nd hand ones available on eBay.
