My right knee is popping it has popped before but it is really popping and when it pops it is a painful pop. I'm afraid of it exploding. My left knee also pops. It is not a painful pop. After the pops in my right knee my leg gives out or up. I can't put much weight on it. In 1995 it blew up like a balloon. I don't remember a pop.
