From what i know there has been great advancement in different types of bunionectomy procedures. The best thing is to talk with your doctor about expectations and what other patients have gone through. Ask about what type of hardware if any will be used, and your activity limitations post op.
I know the expectations and the actual post op recovery has greatly changed over the past decade. If you ask someone who had a bunion fixed 10 years ago they may tell you it was the worst thing ever, compared that to someone now a days who may have a newly revised procedure and was able to deal well with the post op.
Best thing you can do is go to see ur doctor with a list of questions already compiled.
