Angela, my sympathies - I tore my posterior tibial tendon a few years ago, although not so badly and no surgery needed.
I got an iWalk 2.0 when I broke my ankle, and used it a few times but had problems with pain from the cast and later the boot that stopped me using it much. I think if you can get used to it it would be great. I suspect that using it after tendon repair might work better.
If you are in the London (UK) area you could try mine out!
