I'm at about 10 months and not a day goes by yet that I don't notice my TKR in one way or another, I still experience swelling most days and the replacement knee area seems bigger than my regular natural knee. I have some aches and pains from time to time, my biggest problem for me would be the swelling, but I continue to see progress, used to have trouble getting into my husband's pickup truck normally, about a week ago I noticed I was able to get in normally again, ( instead of looking kind of dorky. ) So I guess what I am saying is I think a lot of what your experiencing may be normal at this pt yet, unless you pain is really, really bad and preventing you from using your new knee. Recovery is a very, very long road. If you are experiencing pain that you think is more than you should be having at this point in time, seek out you O.S. advice, if you have something else going on it would be better to catch it sooner than later on.
