My right knee pops when I straighten it. It is also painful at different intervals during the day. It is not painful all the times. Yesterday I was standing in the kitchen and all of a sudden my knee felt like it was out of placement. I had trouble walking. Very painful and the pain eased up and came back later during the day.
