Cracking the Myths: Understanding Joint Noises and Their Impact

Joint noises like cracking or popping are often considered a sign of aging or arthritis, but they are usually harmless and not linked to joint damage. These sounds are explained by processes like cavitation and crepitus. Remaining active benefits joint health despite potential noises.

Joints can make various noises such as cracks, pops, or creaks, which often cause concern about aging or arthritis. However, experts assert that these sounds are usually harmless and not indicative of joint damage.

The phenomenon is generally caused by cavitation, where gas bubbles in the synovial fluid collapse, or by crepitus, which involves movement between cartilage and bone. Knees are particularly susceptible due to their structure.

While the sounds themselves are typically not an issue, they should be evaluated if accompanied by pain or functional limitations. Maintaining an active lifestyle is critical for joint health, as regular movement provides necessary nutrients to cartilage.
