My mother-in-law had both knees done, about 3 years apart. She is glad she did them, but the absolute worst thing is that she can't kneel down. You would still have a good knee to kneel on, but keep that in mind. I would expect things to get better as technology improves. They told her they could only do the replacement twice, so you would get about 30 years out of the 2 surgeries, assuming you live that long. :wink:
