mysticdoc :

Hello

mysticdoc :

Thanks for your question.

mysticdoc :

The clicking and cracking sound are due to the release of the entrapped air in the joint fluid.

Customer:

Is it bad?

mysticdoc :

This is a normal phenomenon if you do not have any other symptoms like knee pain or stiffness.

Customer:

I have some knee pain at times, not always though

mysticdoc :

ok

mysticdoc :

do you have free range of movement?

Customer:

Yeah, but mid way through extending my leg it clicks pretty loud. It usually doesn't hurt.

mysticdoc :

ok

Customer:

Anything I can do to stop it?

mysticdoc :

do quadriceps strengthening exercises.

mysticdoc :

this will help in minimizing the noise.

Customer:

Sweet, thanks. I've heard that leg extensions were bad for the knee, is there any truth to this?

Customer:

Something about the machines engaging one knee and not the other, or something

mysticdoc :

no this is not bad.

Customer:

Ok cool, thanks a lot
