Just wondering if anyone else has had any experience with their knee replacement feeling like something moved, indurations around the knee cap that disappear after walking for awhile, and a large, well not sure what to call it. At first they said it was swelling. But seven months later it is still there. It is the area that was totally numb on the outer side of the knee. The feeling is coming back but it hard like bone and if you hold your hand there while i bend my knee back and forth you can feel it crunch. What is going on with this? Anyone else have this happen?
