My surgery was a success by the foot surgery's standards but I ended up with atrophy in my calf. It's doubtful that it'll ever be better.

I had ankle surgery (tendon transfer plus calcaneal osteotomy, which involved cutting the heel bone and reattaching it in a different alignment) in Syracuse, NY. No problem healing, though it was a long time before I got back to full activity, and I still have some problems in my feet. I think they usually put in some bone growth stimulator to help the fusion. Another thing I did (have no way to know if it helped but think it might have), I ordered supplements from www.makemeheal.com that are specifically geared to help with healing after surgery, cut down on bruising, etc. I healed really well.
I had worn a rigid AFO (ankle-foot orthotic) for most of the 3 years before that, and only when that didn't work did I go for the surgery. I have no regrets about that, it made my ankle SO much more stable! My calf muscles did atrophy with the AFO (though I didn't sleep with it) but it came back after ward with exercise. I use a recumbent bike for exercise (when I can make myself do it), and before I could do that, I had a little Chattanooga pedal exerciser. The tendon I had reinforced was the posterior tibial tendon. If you happen to be in the NY state area and want to know where I went, email me at egalo"at"stlawu.edu
