Total knee replacement

Prayers and best wishes for your Lady.
I have multiple friends that have had one or both knees done. In ALL cases the only complaint is they waited too long to have it done.
My girlfriend (one done,, one waiting)says it makes a difference who does the surgery, but everyone who has had it done by Kaiser is happy (six knees that I know personally there.)
My girlfriend walked in the house within four hours of her surgery, but she was still drugged to her eyeballs. And her pain tolerance is thru the roof.....
Best advice? DO THE REHAB exactly as ordered!
