My dear mother is in the hospital. She had not ONE but TWO of her knees replaced.
I don't like to brag (shut it) but she is sort of a ROCK STAR!!! In fact, people keep coming in to meet her because in their morning meetings she always comes up as an example of "great attitude".
She is up and walking, doing as many exercises as they will let her and basically just setting this place on fire. When she tells people she's going to rehab they ask her, "why? what are you going to do there?"
She is a great patient. They had given her six weeks of exercise to do before surgery and she did them. She followed all of their pre-op instructions. She decided as she came through the door that this was going to be a great experience for her and for everyone she met. And guess what...That's exactly what happened.
