I returned to work in 3 weeks, as I sit at a desk all day. I brought a zero gravity chair into the office to keep my leg up and that helped some, but as others have stated, it swelled up every day! By 2 - 3 p.m. I was physically exhausted and had to go home and sleep after work. I found that if I worked a few days, then took a day off, I could survive, but it is really draining. I can't imagine being on my feet at all. I am six weeks, this week, and still am having to leave early and take time off every week. Good luck, I know how hard it is to have obligations, and try to heal at the same time. Most people that have not had this surgery, I find have no idea how extreme it is. I have a X-ray laminated card of my new knee in my wallet that I share when someone makes a ridiculous remark, like I figured you would be back by now, and feeling great. Once I show them the card, their jaw drops and they quickly Get it! I don't feel like my sitting in a chair is doing any damage to the new joint, but if I had to stand all day, I would lose it mentally, physically for sure.
