question: I had knee replacement one year ago..the alignment has never felt right. Me knee feels heavy and though I have exceptional range of motion, I have to almost work to swing the leg to walk. The kneecap always feels tight as though someone is holding it and trying to pull it off.My foot is not straight when I walk, it is pointed outward. I now have extreme pain in my hip. What do you think this is. My right knee was replaced prior to this one by the same surgeon, but with a different implant. It is a work of art.
