knee replacement op?

Our bathroom/toilet is downstairs, and although I`d been shown how to go up and down stairs, I chickened out and slept downstairs for the first few weeks home. I still have problems getting up stairs, not quite so much coming down, but we have a stair lift, which is a boon. DO keep up with the exercises, they do work..........eventually.

She will be given instruction on what she can and can't do. She will have climbed a flight of stairs before discharge with the help of a stick/crutch but may not want to have to do that every time she needs the loo. A commode would solve the problem but she may well feel able to manage quite well.

They do teach you to get up and down stairs a few days after the operation. We only have 2 storeys with a loo on each so I didn't find it a problem. What she will need will be help getting up and down on the loo. Usually they will sort you out with a loo seat with arms that you can use till you can cope without it.
You aren't supposed to drive for about 6 weeks after the op, when I had my left knee done I was back driving much sooner because my car is an automatic.
The most important thing is to really keep on with the exercises the hospital give you. It gets boring and it hurts, but it really makes an enormous difference to the outcome. If your sister has been having a lot of trouble with her knee she will find the replacement makes a huge difference. It's eight years since I had both mine done and I've never regretted it for a minute!
