As we know, where two different bones meet is called joint and stay connected through connective tissues. And we generally hear a noise when we crack these joint. The sound seems to be like ‘Tak’. Joint makes sound like popping, cracking, grinding. The noise can be heard while cracking

Knuckles maknig sound

, knees,neck, ankles and back. The lot of study shown different reasons why
this process make sound off, some are

Bubble Burst : Basically all the joints of our body is surrounded by a fluid which is clear and thick called synovial fluid. There are some gases dissolved in this fluid. When joints are pull apart in the process of cracking, the connective tissues are stretched and gives increment in volume. That makes pressure to decrease to a certain level that makes the gases in the fluid to become bubble. As the pressure further drops it makes the bubble burst that makes the sound we hear. This process is called cavitation which is very fast. Also if we try again to make the noise, generally not possible because gases takes time to dissolve again.

Knees making sound of cracking

Joints, tendons and ligaments movement : When joint moves, it cause to change the tendon’s position and when the same tendon comes to the same place it makes a snapping sound. Also when ligaments got tighten in our knee or ankle, then also we may hear the cracking sound.

Although study suggests that there is no harm in this process but habitual knuckle crackers did show some bad signs like their grip strength decreases, also after a certain age hands used to vibrate for no reason. Also the soft tissues may be damaged in this process so be careful enough. It is also true that we get increased mobility in joints after doing this cracking that makes the body parts work well. The most important is that if you feel pain in this process then you should go for some health professional. Also don’t do neck cracking, it may be harmful because of its sensitiveness.
