Seeking advice from a non-medical site is like getting personal advice from one of the old "lovelorn" newspaper columns.
I found there is not any absolute advice on each person.
Between the injury and the work performed in therapy, every one is different. Your doctor and physical therapists are best. Individually, look for ball park figures on your injury.
Some can recover quicker, and some do it poorly. Your medical people have seen it all. They can't paint one picture.
On my injury/illness, it covers all things, it seems, from non experts. Uncle Jed was bedridden five years and died; some it seems. some one they knew, recovered quickly. I did well to amaze some people. It was a mixed bag according to people and their limited experience. And I was attempting to avoid advice at all costs.
I went on my own and worked on what I had to do, by myself. I just finished my recovery walk in the park. I notice a lot of the energized walkers lost their energy dieting for weight reduction, once the weather turned colder than 50 degrees. I guess weight losing is off until the warm weather returns.
