Should be OK: We used think that knuckle-cracking is bad and one may develop arthritis..There is no such evidence. As long as you are not having pain or instability in your knee, popping/crackling by itself is likely harmless.....

Cartiage: May have some cartilage damage. Other possibility is the fat pad behind the patellar tendon.
