I am four years out from the same injury. Sorry to hear about yours. Religious participation in PT is the key. If you want to keep the pounds off, use the crutches the whole time rather than the scooter. That’s what I did. I literally crutched everywhere, upstairs, downstairs, through the airport, etc. terrific workout.
With religious participation in PT, I was physically back in 6-9 months. It took another two years before for me to get back mentally in relation to water skiing, but taking it slow was worth it.
The mental come back in snow skiing and other sports was faster.
Good luck and stay positive.
