Thanks for your question.
The clicking and cracking sound are due to the release of the entrapped air in the joint fluid.
Is it bad?
This is a normal phenomenon if you do not have any other symptoms like knee pain or stiffness.
I have some knee pain at times, not always though
do you have free range of movement?
Yeah, but mid way through extending my leg it clicks pretty loud. It usually doesn't hurt.
Anything I can do to stop it?
do quadriceps strengthening exercises.
this will help in minimizing the noise.
Sweet, thanks. I've heard that leg extensions were bad for the knee, is there any truth to this?
Something about the machines engaging one knee and not the other, or something
no this is not bad.
Ok cool, thanks a lot
