My husband had this done two years ago.
His was done at a surgery center. he was really loopy when he came to. He was rxed pain meds. He was on crutches for a week. I remeber because it was done on June 26 of that year and we went to a Forth of July fireworks thing close to the fourth, and he was made, because the spot I had picked out for us to sit at, was up a steep hill....he griped until I pointed out the sidewalk for him to walk up and over to the blanket.
He had to go to PT. On his first day, they made him climb up a set of steps and ride a bike. He said the steps weren;t bad, but the bike was killer. As he went to PT things got easier. His knee is fine now, for the most part, he has a few twinges every now and then, but nothing like the pain he used to have.
The funny thing is, my husband grew up playing baseball, and he still plays softball of the weekends. By college he knew his knees were shot. So later, he finally gets in to see a sports med doctor to complain about his left knee. So the doctor looks at him over a few visits, requests an MRI, and really never sees anything on the x-rays and MRI. He does see a buildup of fluid/placa(?) so he decides to do suregery to remove the placa. It was only when he inserted the scope he saw the tear of my husband's MCL, which again never showed up on anything. The doc thinks it was hidden by fluid. He later told the hubster that it was good thing he decided to go in.
