I have always had a problem with hyperextension in my knees. I had TKA in Dec. The post in my joint replacement is trying to pop out of the groove. I am wearing a immobility brace at night. This seems to have helped. I have not had the joint hurt or try to "pop out of palce" since I have been sleeping in the brace. I was just wondering if anyone had this happen to them. My OS said it was not rare but it was usuaual (like 2%). I am suppose to sleep in the brace at night and I am not suppose to use any brace during the day until I go back to my OS in March.
