In reply to hymac: I'm getting a triple fusion in a few weeks and according to my surgeon here are pros & cons in brief-
Pros- Stop arthritic pain/discomfort in ankle, should help sort alignment problems in knees (excruciating) and hip due to compensating for ankle for 3 years.
Cons- At least a year recovery time and obviously no more ankle movement but Dave Macleod injured his ankle years ago and it hardly moves but he seems to do okay.......
