My first thoughts as an 81 year old.:
a] Set-up a pre-op physical therapy session. The doctors will talk about at home physical therapy but if someone can drive you, at their center is much better.
b] The bandage will be huge! (over 2 pounds of padding and elastic wrap) so wear extra large slacks.
c] Take your walker to surgery. I took my old crutches. They put me in a wheelchair as my wife got the crutches and I left the building on the crutches.
procedure started at 9AM after surgery waited for the surgeon to do another patient, then left the building a 2PM.
d] Next day I walked around the block on crutches with my wife.
e] 2nd day, walked a 1/2 mile.
f] 3rd day, removed the huge bandage.
g] small Range of Motion my make cycling a problem.
