Many people like the common activity of knuckle cracking. It may become a habit or a strategy to manage anxiety; some people refer to it as a way to “release tension.” Some people find it annoying when other people do it.

Read on if you’ve ever wondered why some finger stretches make that well-known noise or whether knuckle cracking is hazardous. Despite how frequent it is, there has been much discussion about the noise source. Fortunately, at least for those interested in learning more, some research has been done on knuckle cracking. Usually, people ask, “Is cracking your knuckles bad for you? Cracking your knuckles does not appear inherently bad for you, as several studies have not found a direct link between knuckle cracking and arthritis.

Understanding Knuckle Cracking-

Here is some information on knuckle cracking.

  • Increasing the distance between finger joints appears to cause the “cracking” sound associated with knuckle cracking. Gas bubbles within the joint fluid collapse or burst due to this. It’s similar to blowing up a balloon and then straining its walls until it bursts.

  • It takes some time for the gas bubbles to gather once more in the joint, so you can’t immediately crack the same knuckle or joint repeatedly.

  • Knuckle cracking is probably not harmful. Although too-aggressive knuckle cracking has occasionally been linked to reports of dislocations or tendon injuries, these incidents are the exception rather than the rule.

Why do people knuckle crack?

Is cracking your knuckles bad for you?

More than 50% of adults commonly crack their knuckles, which can be brought on by a variety of factors, according to studies. People love hearing these pops and cracks for a variety of reasons, some of them are as follows:

  • The sound appeals to them.

  • They enjoy the sensation of stress being released.

  • It stems from anxiety.

  • Some folks engage in it to decompress.

Does knuckle popping relieve discomfort?

Some believe that popping their back or knuckles relieves them. This may be the case if the release of nitrogen relieves joint stress, but alleviation may also be brought on by the stretching occurring simultaneously.

Doctors think those with joint pain should be aware of a crucial message. After doing so, it’s time to contact a doctor if you experience any pain in your neck, back, or knuckles. Investigation is necessary because pain is not typically linked to this activity.

Why does it make a “cracking” sound?

Your synovial fluid, which lubricates your joints, contains bubbles that pop when we crack your knuckles, which produces a “popping” or “cracking” sound. These bubbles explode when you force your bones apart because of a buildup of negative pressure. Additionally, when you stretch or bend the joints in your fingers, your ligaments may shift and cause your joints to make a popping noise. Imagine doing a bubble burst with a chewing gum stick.

What are the negative effects of knuckle cracking?

Contrary to popular belief, arthritis does not develop due to knuckle cracking. However, carrying it out incorrectly or with excessive force could harm your hands.

A dislocated finger-

The joints between your fingers and the rest of your hand are called metacarpophalangeal joints or knuckles. Even though these joints are very secure, they are nonetheless susceptible to dislocation if enough pressure from the outside is applied. The index and pinky fingers are typically affected.

Ligament sprains-

Ligaments are tissues that link your bones together where a joint is located. Sprains occur when supportive ligaments get overstretched or torn due to twisting, struck, or other trauma. You can experience a snapping or tearing feeling when your finger is sprained.

Is there any proof that knuckle cracking is harmless?

One of the strongest and biggest pieces of proof that knuckle cracking is safe is from a California doctor who wrote about an experiment he ran on himself. He had always cracked his knuckles, but just on one hand. After years of this practice, he analyzed his X-rays and discovered no difference in the arthritis in his hands. A more extensive investigation also reached a similar finding.

Rare medical reports of issues linked to this behavior are related to the amount of force used and the technique used. For instance, joint dislocations and tendon injuries have been reported following knuckle-cracking attempts. A 1990 study showed higher cases of hand edema and decreased average grip strength among 74 people who frequently cracked their knuckles compared to 226 people who did not. However, both groups experienced the same level of arthritis incidence.

Another study’s development of a mathematical model of a knuckle also confirmed that the noise is caused by bursting gas bubbles.

How much knuckle cracking is too much?

The amount of knuckle cracking someone does over time may impact their risk for osteoarthritis, according to a 2011 study that looked at “crack years,” or the number of times someone cracks their fingers.

The good news is that osteoarthritis and joint edema risk are unaffected by the frequency and length of knuckle cracking.

Will joint cracking lead to osteoarthritis?

The phenomenon of “popping knuckles” and “cracking joints” is intriguing and little understood. However numerous ideas explain why joints fracture or pop, but the precise reason has yet to be discovered.

Joint cracking that is painless is typically safe. However, common sense implies that repeatedly and purposefully cracking one’s joints could be both socially and physiologically harmful if it causes discomfort in addition to being annoying.

There is no evidence that knuckle “cracking” is harmful or helpful. Knuckle cracking specifically does not cause arthritis.

Negative pressure can cause nitrogen gas to temporarily enter a joint, causing “cracking” of the joint, as happens when the knuckles are “cracked.” This poses no threat. In cases where tendons slip over tissues due to slight deviations in their gliding trajectories, “cracking” noises can also be heard. As muscles deteriorate with age, this can happen.

If pain is present along with the cracking, there may be underlying abnormalities of the joint’s tissues, such as torn ligaments or loose cartilage. Some people with tendinitis, bursitis, or arthritis (joint inflammation that is typically painful) hear “cracking” noises due to the snapping of atypical, swollen tissues.


Both positive and harmful things can come from cracking your knuckles. People only do it occasionally. It is the sole option for some people to reduce stiffness. Others do it out of habit. Some people engage in it for the loudness or because sending people who don’t crack their knuckles out of the room is entertaining.

Neck, back, or knuckle cracking is likely not harmful but can be painful. In that situation, it can be an issue with the joint’s anatomy or the areas around it, including torn cartilage or damaged ligaments. Arthritis or another condition, such as tendonitis, may also contribute to cracking pain. If you suffer an uncomfortable sensation with joint cracking, go to your doctor to address the underlying issue.
