Express Action Sports

I play an action sport(paintball) where slide and diving on my knee is very common. I wear knee pads and do stretches before I play every time i go out. My knee never gives me any pains or anything like that and it never pops or cracks, but it has been making a sort of squishy noise when i crouch and get back up, i can make this noise when ever i want. Its kind embarrassing cuz its loud and no one really knows what it is but me. I have a feeling it has something to do with my cartilage. Should i worry about this?

you might have misculus damage that is why it creaks, i have the same problem, go get a MRI to check.
