Does cracking your joints especially the knuckles cause arthritis?

No it doesn't. This is a common misconception. Your joints contain fluid which assist in cushioning and preventing the two or more bones from grinding against each other. Cracking your knuckles or joints forces the fluid into other parts of the joint. The popping noise comes from the high pressured rushing of fluid.

Rheumatoid arthritis is characterised by the loss of joint fluid from the joint, but it results from damage to the linings of the joint itself. There is no evidence to prove that high pressure fluid flushing causes damage to the joint linings.

The concept of arthritis being able to be caused by cracking your joints is just an urban myth. No

Arthritis and Cracking Knuckles

The reason people associate knuckle-cracking with arthritis is because it makes a cracking noise and, if something cracks, it must be being damaged. However, the truth is that nothing is being cracked.

A joint is any place where the ends of two bones meet. Where the bones come together they have a covering of "articular cartilage." This is surrounded by the "joint capsule," inside of which there is synovial fluid. Synovial fluid is the lubricant for the joint and also serves as a source of nutrients for the cells that look after the cartilage.

Synovial fluid has dissolved oxygen, nitrogen, and carbon dioxide within it. When the right pressure is applied to a joint, the area inside the joint capsule expands. However, the expansion is limited by how much synovial fluid is contained in the joint. Synovial fluid cannot expand unless pressure inside the joint capsule drops and the dissolved gases can escape out of the fluid. The cracking sound comes from the gases rapidly being released from the fluid.

There have been a few studies to see whether or not cracking knuckles caused arthritis. None have found that there was an increase of arthritis among knuckle-crackers; nevertheless, a relationship was discovered between knuckle-cracking, hand swelling and lower grip strength, damage to ligaments surrounding the joints and dislocation of tendons.

The conclusion of the studies indicated that while knuckle-cracking was not associated with arthritis, it was associated with damage to ligaments that surround the joint and dislocation of tendons. There may also be a connection with soft tissue injuries.

cracking your knuckles will not cause arthritis, However actual cracking bone can lead to certain types of arthritic pain in the future.
on some people it might be bad four them ,but to me it fells good it's just air bubbles in your fingers it wont do any thing.
There is no evidence that cracking the knuckles caused arthritis. In the first place no one knows exactly what arthritis is. they only know what the symptoms of arthritis are. cracking the knuckles does not appear to increase the chances of people developing arthritis. The cracking noise is caused by gasses from the sinovial fluid Nitrogen, Oxygen and CO2 being allowed to escape when the joint is forced apart. While it does not cause arthritis It does cause some swelling in the joints joint displacement Stretching of the ligaments and weakening of the grip. It does NOT. Research has been done and found that knuckle cracking does NOT cause arthritis.

A retrospective case-control study examined the hand radiographs of 215 people (aged 50 to 89) and asked if and how often the subjects cracked their knuckles over their life (1). The study concluded that knuckle-cracking did not cause hand osteoarthritis, no matter how many years or how often a person cracked their knuckles.

No cracking of joints will not cause arthritis. the sound made by this habit is the release of gasses from the synovial joints and is in itself not particularly harmful. however the habit does cause irritation to the joints and brings about unnecessary stretching to ligaments surrounding the joints.
There is no evidence available at al that cracking joints leads to arthritis. The cracking sound is a result of gas being released from the synovial joint.

In fact, it does harm your knuckles! I'm the living proof. It doesn't hurt, but the joints I cracked are swollen. The X Ray scans certainly didn't look pretty. Probably damaged ligaments said the doctor. In case you wonder: my general health is excellent, I have never broken a bone in my life and no one in my family has arthritis, neither do I. So, speaking from experience, please be careful. It does not make your fingers less functional, but it does make them ugly. That is, 3 to 5 millimeters extra on every side of a cracked knuckle.

My currently malformed fingers give me a serious psychological strain. I always close my hands, slightly hiding it. In public I even try to imagine the viewing angle of others and turn my hands accordingly. Some dreams I have, like speaking in front of a public, will never come true just because of the fear it gives me. It's not a fun situation and if the damage could be reversed I would do so right away. Even now I hope for a future medical evolution making it possible to have this reversed.

I've been cracking my fingers from age 10. That's when it all started. I saw an aunt doing it, and I wanted to try the same. I couldn't crack mine vertically, but with a little effort it did work horizontally. I've been very stressed during my youth and somehow this released my stress a bit. I gradually turned it into a habit. I cracked my fingers whenever I could, maybe every 15 to 30 minutes, almost every single day. I believe that from age 12-13 it became visible and towards age 15 it was rather severe. Over 15 years later I'm not where I wanted to be. My current job (webdeveloper) allows me to feel more comfortable, but my real dream would be to work with people, not with computers. As you can see, this has quite an impact.

You may cope with it better than me, but I do not wish such a thing for you.

i have been cracking my knuckles since i was 4 i whatched a film called monsters ink and the big monster guy craked his knuckles and i tryed the same i am now 13 and my fingers hurt a little so i am taking this as a warning that you probly will get Jon problems when you are older although my jointes are already messed up so that ould just be me
