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, you’re 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 person’s own immune system attacks their joints.
