Does anybody have any tips/suggestions on what I can do for exercising with an artificial knee? Currently I am:

1. Walking on a treadmill

2. Using the eliptical

3. Riding a recumbent bike

4. Swimming

Because of the the artificial knee I cannot do squats, lunges or things like that. I also cannot do any weight lifting which would put extra pressure on that joint. I feel pretty good about far I have come since my surgery, but I want to make sure and reach my goal so any help/suggestions that I can get is all the better. Thanks in advance!

Well you should be able to do any of the upper body weights that do not involve weights but I think all of the other exercises that you are doing are great. I would just try to increase your speed or length of time that you are doing them as your body allows. DO not be too aggressive as you do not want to injure yourself.

Honestly, I think you should see a physiotherapist or kinesiologist, as you have a unique situation and none of us are professionals who know the consequences of doing something with an artificial knee.

That said, you could still lift upper body weights - you'd just have to use machines and benches. You can still do bench presses, chest flyes, seated bicep curls, tricep extensions, etc without standing.
