Try not to worry, your knee should be fine. As long as you donít have pain you will get used to the weird feeling all TKRís clunk and move around a bit (Some more that others)
there is nothing like your own knee but at least you are pain free and as I said you will get used to it, as MyKnee2010 says, 7 months is still a short time after the op, give yourself time, at least 18 months.
My knee sounds like castanetís when I wiggle my lower leg,
I can make it clunk whist sitting and it clunks audibly whilst walking (Itís a great party trick) It used to worry me sick but now itís just something that I have to live with and most of the time I just ignore it.
MyKnee2010, Sorry to hear that you are still in pain, good luck in September I hope you get some answers and that they can resolve the problem.
Good luck to you both.
