Facts and myths about cracking your joint

Facts and myths about cracking your joint

You're not alone if your knee makes a snapping sound when bending down, your shoulder joint creaks lightly when you lift anything, or your knuckles make a popping sound when you press on them. Most of us have at some point of time heard our joints make these noises. But should these noises cause us any worry? Let us look at the truth behind joint cracking.   

What is a Joint?


Two bones combine to provide movement in our bodies at a joint. Together, several elements inside each joint—including cartilage, synovial fluid, and ligaments—allow for smooth motion. Long-standing studies on the mechanics of joint cracking have produced a generally accepted theory whereby the collapse of gas bubbles inside the synovial fluid generates the noise. Joint noises such as clicking or cracking when moving, can also be brought on by muscular imbalances or weakness.

Fact: Joint cracking is common.

Does cracking your joints cause arthritis?

Arthritis is sometimes attributed to cracking your knuckles or other joints. Scientific studies, however, have revealed no connection between Arthritis and joint cracking. Studies comparing persons who consistently crack their joints to those who do not have shown similar rates of Arthritis. Though it could be upsetting, the noise does not lead to long-term health issues or joint damage.

Myth: Cracking your joints cause Arthritis

Cracking your neck can be risky

Although occasional,  moderate neck stretching can help, frequent or forceful neck cracking can be dangerous. Important blood vessels and nerves abound in the neck and improper neck cracking can cause pain, Vertigo, or even nerve injury. See a medical professional, such as a  physiotherapist or chiropractor, if you crack your neck often or are in pain.

Fact: Cracking your neck by yourself is dangerous.

Some joints crack more than others

Some people may find that particular joints, like the knees or shoulders, crack more often than others. Usually, this results from differences in joint structure, muscle tension, or joint movement. Because of their range of motion, high-mobility joints, like those in the fingers and shoulders, are likely to crack more often.

Fact: Certain joints crack more often because of their specific movement patterns and construction.

Can joint cracking point to a hidden issue?

Usually, joint breaking poses no major concern. Should pain and limited range of motion accompany the cracking sound, this could point to an underlying condition like inflammation, cartilage wear, or ligament problems. See a qualified physiotherapist if you are also regularly uncomfortable and if joint cracking is not the only cause.

Fact: Cracks in painful joints could point to an underlying medical condition.

Does stretching help in reducing joint cracking?

Frequent stretching and strengthening activities help to maintain joints in good condition and reduce joint cracking. Tight muscles can strain joints, raising pressure and increasing the frequency of cracking. Through targeted exercises and increasing flexibility, joint cracking can be reduced

Fact: Joint cracking can be avoided in part by stretching and strengthening exercises.
