Do you enjoy popping your knuckles in your leisure time? This habit may be frowned upon by many, calling it an unhealthy one. Many people crack their knuckles habitually, unconsciously, or sometimes for relief. The sound is caused by the bursting or collapse of gas bubbles in the synovial fluid within the joints. But does this behavior lead to arthritis?
Does knuckle cracking cause arthritis?
Cracking your knuckles does not increase the risk of arthritis, but if it leads to discomfort or swelling, it’s best to moderate the habit. Prioritizing overall joint health through exercise and good hand care is a more effective way to prevent joint issues in the long run. Multiple studies, including a recent one published in Arthritis & Rheumatology, have found no evidence linking knuckle cracking to arthritis. Researchers compared habitual knuckle crackers with those who don’t crack their knuckles and found no difference in their likelihood of developing arthritis.
What happens when you crack your knuckles?
According to Dr. Supreet Bajwa, Consultant Orthopaedic Surgeon at Wockhardt hospitals, Mumbai Central, “Cracking your knuckles involves a quick stretch of the joint, leading to the rapid release of gas—mainly nitrogen—from the synovial fluid, which lubricates the joint. This gas release produces the characteristic popping sound.”
Potential side effects of habitual knuckle cracking
Is knuckle cracking harmful?
According to Dr. Ashish Phadnis, Director of Orthopedics and Joint Replacement at Jupiter Hospital, Thane, “While cracking your knuckles does not cause arthritis, frequent or forceful cracking may lead to:
Reduced grip strength – Frequent cracking might weaken the hand’s ability to grip firmly. Decreased grip strength if done excessively
Swelling of soft tissues – If done forcefully, it could cause mild inflammation or discomfort. Temporary swelling in the joints
Underlying joint issues – Pain or swelling after cracking could indicate a pre-existing joint condition that needs medical attention.
How to maintain healthy joints
For better joint health, consider these habits:
Engage in regular exercise to keep joints flexible.
Maintain a healthy weight to reduce stress on joints.
Practice proper hand ergonomics, especially if working with keyboards or manual tasks.
Avoiding repetitive strain to prevent unnecessary wear and tear
Gentle stretching to maintain mobility and reduce stiffness
Knuckle cracking does not cause arthritis, but excessive cracking may lead to temporary discomfort. Practicing good joint care can help ensure long-term mobility and strength. If persistent pain or swelling occurs, consulting a healthcare provider is advisable.
