They had us up and walkin' 3-4 hours after my surgery at 30.06 free TMF in Tyler after my knee replacement last year. My shingles outbreak that morn kinda' kept 'em at a distance but a couple of laps, we did do.
I had my 71 year old left knee replaced about 18 mos. ago. There's nothing to it. The absolute worst thing you can do after surgery is NOTHING. The sooner you get up and get moving, the sooner you'll be out of rehab and back on the dance floor.
