Thanks to new high speed images, it seems knuckles crack when a bubble forms (and not the other way around!).

As tension increases, a cavity suddenly opens between joints that air rushes into; this creates the loud “crack”. The bubble then remains for about 20 minutes until slowly dispersing, making it impossible to crack until the bubble is completely gone. 

Researchers aren’t actually sure why the sound is so loud so research is still ongoing. As for cracking knuckles giving you arthritis? Research points to the ability of being able to crack knuckles as a sign of healthy joints, provided you don’t force it.
