My late father in law had arthroscopic knee surgery about 20 years ago. I drove him to and from the hospital. He walked out of the hospital with crutches, almost fell down the steps, tossed them to me and walked to the truck without them.
I had meniscus surgery and was walking fine in a few days. Started my own rehab exercises and when I went back for the 2 week checkup, doc told me, you don't need rehab, you're doing fine. 4 weeks and I was fine. Of course, that ain't playing football, just working construction.
