So I Can Crack My Knuckles Freely There’s No Risk Of Arthritis
There are several types of arthritis, but knuckle-cracking is most commonly associated with osteoarthritis. In simple terms, “Osteoarthritis is a disease where the articular cartilage, located at the end of the bone on each joint, starts to break down and flake off,” causing pain, stiffness and swelling over time, Dr. Fackler explains.
“Osteoarthritis is age- and genetic-related…and people don’t get significant osteoarthritis until they’re in their 40s, 50s or older,” Dr. Fackler says. “The vast majority of arthritis patients have a genetic predisposition to the disease. However, if you have an injury when you’re young or tear a ligament or meniscus, that puts you at higher risk for arthritis when you get older.”
Other Habits Associated With Knuckle Cracking
One research study of 300 people reported that people who cracked their knuckles were more likely to have manual labor jobs and smoke.7
Manual labor can be a risk factor for osteoarthritis. If you have a manual labor job, finding ways to reduce daily stress on your joints may be more important than quitting knuckle cracking to lower your risk of arthritis.
Likewise, quitting smoking or other nicotine use can reduce your risk of serious medical problems, including lung cancer, heart disease, stroke, and chronic obstructive pulmonary disease .
The Truth And The Myth Behind The Cracking Knuckles Debate
Cracking your knuckles may aggravate the people around you, but it probably won’t raise your risk for arthritis. That’s the conclusion of several studies that compared rates of hand arthritis among habitual knuckle-crackers and people who didn’t crack their knuckles.
The “pop” of a cracked knuckle is caused by bubbles bursting in the synovial fluid the fluid that helps lubricate joints. The bubbles pop when you pull the bones apart, either by stretching the fingers or bending them backward, creating negative pressure. One study’s authors compared the sudden, vibratory energy produced during knuckle cracking to “the forces responsible for the destruction of hydraulic blades and ship propellers.”
Even if knuckle cracking doesn’t cause arthritis, there’s still good reason to let go of the habit. Chronic knuckle-cracking may lead to reduced grip strength. And there are at least two published reports of injuries suffered while people were trying to crack their knuckles.

Can You Get Arthritis From Cracking Your Knuckles
How often do you crack your knuckles? It is true that almost all of us love cracking knuckles at times in our life, and it also feels good and relaxed sometimes. However, there are also some people who are in to a habitual cracking of knuckles. Though rare cracking of knuckles may not cause any serious issues, however those who are habitual to cracking knuckles have something real to worry about. This current article will talk about cracking knuckles where we will talk about the causes of the cracking sound while cracking our knuckles, effects and also know about some ways to stop cracking knuckles.
But Wait There’s More Here’s What You Shouldn’t Crack
Dr. Fackler advises avoiding popping the neck, as it can cause inflammation around the nerves and lead to more serious injuries long-term. “I encourage people not to habitually pop their necks, especially kids.”
So, as it turns out, you can crack your knuckles, limitlessly, without the consequences of arthritis. Just don’t be too caught off guard if your rings fit a little tighter after a knuckle-cracking session. Cracking knuckles can cause temporary swelling or a subtle increase in the size of your hands, but is ultimately harmless. “There are no long-term studies that show knuckle-cracking causes any damage,” Dr. Fackler says. Until then, “When it comes to your fingers, don’t even worry about it.”
Snap, crackle and pop away.

What Happens When You Crack Your Knuckles
The need to pop your joints is a medical mystery. No one really knows why this phenomenon exists or its purpose. The mechanics behind joints cracking is well understood, though. A joint is an intersection where two bones connect. The human body has around 360 joints that bring bones together to form a skeleton that is able to bend and move freely.
Joints are surrounded by a membrane full of fluid. The membrane serves to protect the bone caps from friction damage as you move. When you yank on a joint trying to pop it, you create negative space that pulls in some of the fluid. That popping sound that makes Mom cringe is the influx of that fluid.
Does Cracking Your Knuckles Really Cause Arthritis
- Does Cracking Your Knuckles Really Cause Arthritis?
It has long been believed by the general public that the sometimes satisfying, sometimes annoying habit of cracking your knuckles causes arthritis down the line, but does it really? The short answer is no. But before we get into the effects of cracking your knuckles, lets figure out exactly what is going on in your fingers.

Why Do Joints Make Noise
Although noisy joints are more common as people get older, anyone can experience the grinding, creaking, cracking, clicking, or popping sounds. These sounds can be muffled or easy to hear. Even though some people worry about them, joint noises are most often normal and do not usually require treatment or harm overall wellness.
For instance, noisy knees may be alarming, but no evidence suggests that knee sounds are associated with more knee joint problems. Some people intentionally pop their knuckles or other joints as a habit, but there is no proof that knuckle cracking causes permanent joint impairment.
The medical term for joint noises is crepitus. Here are some common causes:
- A tendon or ligament can make a noise when it snaps over a bump in your bone or joint.
- A ligament can tighten when you move, causing a snapping sound.
- Bubbles of air can pop inside the synovial fluid .
- Cartilage can wear away and cause osteoarthritis, in which rough areas in the joints make a grinding or crunching sound.
- Tendon injuries or inflammation , such as tennis elbow, can lead to popping sounds.
- Bursitis, which is the medical term for inflammation of fluid-filled joint cushions called bursae, can cause joint noises.
Will Cracking Your Knuckles Cause Arthritis
The Department of Orthopedics noted there is no evidence that knuckle cracking causes arthritis. However, repeatedly cracking your knuckles may cause temporary soreness of the joint. Knuckles are the joints between your fingers and your hands. These joints are surrounded and lubricated by synovial fluid, a thick, clear liquid. When you crack your knuckles, youre causing the bones of the joint to pull apart. This causes a gas bubble to form in the joint. The cracking or popping sound you hear is the breaking of the adhesive seal in the joint.
The repetitive motion of cracking your knuckles wears down the joints and their protective cushioning. This means individuals who currently have osteoarthritis, caused by the breakdown of cartilage in the joints, could worsen their symptoms by cracking their knuckles repeatedly. However, cracking your knuckles plays no role in rheumatoid arthritis, which is caused when a persons own immune system attacks their joints.

Question: If You Have Arthritis Can Cracking Knuckles / Joints Make It Worse
Answer: No. However theoretically knuckle cracking in patients with weak or damaged joints due to arthritis could potentially lead more easily to ligament injury or acute trauma to the joints.
Founded in 1998, the Arthritis Center at Johns Hopkins is dedicated to providing quality education to patients and healthcare providers alike.
What To Do If You Have Arthritis
Deal recommends you stay active and maintain a healthy diet and weight to manage arthritis. At home, enjoy a paraffin bath. The warm wax limbers the tissues and allows mobility in the joints.
Use medical intervention when needed, Deal advises.
You can manage arthritis pain with physical or hand therapy, finger splints and by modifying your activity. Medication options include cortisone shots or anti-inflammatory medications.
If needed, surgery can help. Depending on where you have arthritis, knuckle replacements or joint fusions can successfully relieve symptoms. Surgery even prevents the treated area from developing arthritis again.

Question: Are There Any Side Effects To Cracking Knuckles
There is no evidence that cracking knuckles causes any damage such as arthritis in the joints. However, a couple of reports in the medical literature are available associating knuckle cracking with injury of the ligaments surrounding the joint or dislocation of the tendons which improved with conservative treatment. A study found that after many years of cracking habitual knuckle crackers may have reduced grip strength compared with people not cracking their knuckles.
What Causes The Pop
The reason the joint makes a popping or cracking sound when pulled is still not completely understood. For a long time, many people attributed the noise to nitrogen bubbles either forming or collapsing in the joint fluid. Others thought it came from movement of the ligaments around the knuckle.
In a 2015 study , researchers watched knuckles while they were cracked using an MRI. They found that a cavity formed due to the negative pressure created when the joint was pulled apart quickly. They determined that the sound was made by formation of the cavity. However, this couldnt explain the loudness of the sound.
A 2018 study suggested that the sound was actually caused by the partial collapse of the cavity. A review of studies noted that it takes 20 minutes for the cavity to fully collapse so a new cavity could be formed. This may be why after youve cracked your knuckles, youre not able to do it again right away.

How To Stop Cracking Your Knuckles
If you are willing to know about some of the ways to stop cracking your knuckles then this is the section you need to take a look on for some of the relevant and effective tricks.
The Truth About Cracking Your Knuckles
Cracking joints can be divided into three categories. The first is the accidental cracking or popping joints you hear when you move around normally. The second is cracking the knuckles in your hand. And the third category is when you intentionally crack other parts of your body, like your neck and back.

If You Crack Your Knuckles Dont Worry Too Much About Getting Arthritis But The Habit Isnt Harmless
Ignoring generations of parents whove warned that knuckle cracking is bad for you, between 20 and 54 percent of Americans continue to engage in this annoying nervous habit. Many have been reassured by repeated clinical reports over the decades that there is no strong evidence that knuckle cracking causes arthritis. A 2018 Harvard Medical School blog went so far as to pronounce the practice harmless.
Harmless is overstating it, however, argue experts who have studied the fine print of the research. Even as theres no strong link to arthritis specifically osteoarthritis, the degeneration of the cartilage cushioning the ends of bones cracking knuckles, they conclude, may still harm your hands.
Seattle neurosurgeon Rod Oskouian is the most recent researcher to jump into this small but lively tributary of mainstream science, as co-author of a 2018 review of knuckle-cracking studies in the journal Clinical Anatomy.
Oskouian and his three colleagues pored over 26 sometimes-contradictory papers regarding the mechanisms and effects of knuckle cracking, beginning with a 1911 German treatise titled On the Dispute About Joint Pressure. He did so, he said, after becoming fascinated by the universal inability of his students through the years to explain what makes that cracking noise.
But that still doesnt give knuckle-crackers a pass especially not if they do it a lot and for a long time, or have a preexisting problem.
What Does Happen When You Crack Your Knuckles
Dr. Fackler explains that the pressure applied to knuckles “causes vapor pockets” within the fluid inside the joints. This then “creates a vacuum that sucks the joint apart rapidly,” causing a popping sound in the knuckles.
So why do so many people find relief in cracking their knuckles? Cracking your knuckles “feels as if it relieves tension in the joints,” Dr. Fackler says. “When that phenomenon happens, it causes a distraction of the joint and separates the joint for a brief second. If traction is applied to the joint, it feels as if it loosens up and is more mobile.”

What Causes The Cracking Sound While Cracking Knuckles
Before we go for learning about the causes for the cracking sound while cracking knuckles, let us know about something called the Synovial membrane and Synovial fluid.
Our joint, including the knuckles are surrounded by the Synovial membrane which is a membrane forming a capsule around the ends of our bones. Synovial fluid is the fluid which remains inside the synovial membrane and acts as a lubricant and shock absorber so that your bones do not grind together while you move.
Now, when we Crack our knuckles or any other joint holding the Synovial membrane and the synovial fluid, it expands the space present between the bones and thus creates negative pressure that draws the synovial fluid in to the new gap. The cracking or the popping sound and the feeling which one experiences while cracking knuckles is that which is caused due to the influx of the synovial fluid in to the new gap.
Let us take a look on some of other suggested causes for the cracking sound produced during cracking knuckles.
- The cracking or popping sound occur when there forms bubbles in joints as they are pulled apart while cracking knuckles.
- Rapid stretching of ligaments surrounding the synovial membrane in the knuckles are believed to produce the cracking sound
- Some suggestions also include that the within joint adhesion are broken while cracking knuckles.
What Is Knuckle Arthritis
Knuckle arthritis is less common than arthritis affecting the other smaller joints in the hand or the joint where the thumb joins the wrist . The most common knuckle arthritis is rheumatoid arthritis. In this situation, the joint lining produces chemical factors that inflame and destroy the cartilage and soft tissue, such as ligaments and tendons. The result is that the joint surfaces are destroyed and the other fingers drift towards the little finger. The causes may include:
- Age: The older we get, the more likely we are to develop arthritis. Over time, our cartilage that cushions and lubricates your joints wear down, eventually leading to arthritis.
- Genetics: Some people are genetically predisposed to developing thumb arthritis. The estimated onset time of thumb arthritis can usually be determined by family medical history.
- Gender: Women are more disposed to knuckle arthritis.
- Previous injury to the wrist or the area surrounding knuckles and finger
If the pain starts to interfere with daily activities of daily living, then a visit with a hand surgeon could be helpful. The diagnosis is usually confirmed using plain x-rays. Special x-rays are also helpful to look carefully at the metacarpal head, particularly in milder cases.

Question: What Causes Arthritis
Answer: There are different kinds of arthritis with the major categories being two: The inflammatory arthritides such as the rheumatoid arthritis and the degenerative arthritis best known as osteoarthritis or wear and tear arthritis. The causes for either are not well known and research focuses on elucidating the mechanisms leading to these diseases. In general a genetic predisposition is highly likely for both. For the inflammatory arthritis an unknown exposure to environmental stimuli is considered possible. For the wear and tear arthritis instead, aging and excessive mechanical stress may play a role in accelerating the damage in the joints as it happens in the knees of genetically predisposed older obese people.
Study Conclusions On Whether Knuckle Cracking Causes Arthritis
There have been a few studies over the years that considered whether or not cracking knuckles caused arthritis. One study found that there was no increase of hand arthritis among knuckle crackers, however, knuckle cracking was related to hand swelling and lower grip strength.
Another study 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. While cracking your knuckles is not linked to causing arthritis, there may be a connection to soft tissue injuries.
A study from 2011 looked at 215 people who had a hand X-ray within the past five years. It’s interesting that 20% of them were habitual knuckle-crackers. The good news for those folks is that they were at no greater risk for hand osteoarthritis and it didn’t matter how long they had been knuckle-crackers or how often they did it each day.
