Something funny, but Genuine -

Cracking your knuckles does not actually hurt your bones or cause arthritis. The sound you hear is just gas bubbles bursting.

Cracking your knuckles (or any of your joints) can have therapeutic benefits. When you crack one of your joints you are pulling the bones that are connected at the joint apart from each other.
This process stimulates your tendons, relaxes your muscles, and loosens your joints.
Chiropractors - the Physicians  who diagnose and treat the defects on musculoskeletal system and there effects on nervous system do this for spinal joints when your back is sore and stiff .You can do this on your own for your knuckles, toes, knees, neck, etc. So never misunderstand that it will lead to Arthritis rather than keeping away from it.But too much stretching of your ligaments will cause damage to your fingers related to the arm injuries endured by some Sportspersons.
