Well, here I am, 7 weeks post knee replacement, and it was absolutely the best thing ever for me. I am completely mobile, only using a stick a shocking pink one!) outside for security, and am pain free. I am so delighted with the outcome.mWell, the opposite hip is crumbling....
However, to return to the real subject; as most people say, they won't let you out of hospital until you have climbed a flight of stairs. I achieved this on Day 3 (op was Weds, this was Fri.) and went home that day. I am NOT a terribly fit and active person, but found it easy enough.
But I would not have liked to do more than one flight for a week or so, or at least not just to go to the loo. (And I did seem to wee a lot during that first week...) I think having a commode as standby would be a good idea.
We have an en suite bathroom, which was very convenient too.
