How bad is it that when I stretch my leg, it pops?

Question

Also I can pop my knees and I'm hearing a lot of rumors about how bad it is but it affects my knees if I don't pop them.

Answer 1

my right leg always pops when i stretch it or sit on it too long, its never been a serious problem for myself I'm almost 22 now and its done it since i was 4 years old. i would say as long as your not in extreme pain, its not serious.

Answer 2

it is just a lack of cartlidge between the bones.
if your having pain you may need surgery.
