Hey there, yesterday I moved my knee the wrong way and it locked in place, it felt dislocated. I couldn't straighten it all because of the pain. I had someone help me stand (on the good leg) and it was like the gravity pulled it out. My knee popped loud and I felt and saw it go back in place. Now today it's been sore the odd movements I do and walking on it is sore as well. Why do you think happened and what should I do? Thanks!
