Most people have experienced joint popping at some point. It can happen at various times, such as while bending your knees, cracking your knuckles, or moving your ankles. The cracking sounds in the joints are typically not a cause for concern, but there are some cases where they could be part of a larger medical problem that needs attention from a physician. Here's what to know.

Common Causes of Popping Joints 

Nitrogen Bubbles

Synovial fluid contains nitrogen and lubricates the joints, helping protect against irritation. Tiny gas bubbles can form in this liquid and escape, popping when you move the joint and creating that familiar sound. This circumstance is the most common reason for the cracking noise and is completely normal and harmless.

Body Manipulations

Popping sounds are also common during massage or osteopathic and chiropractic manipulations. Alleviating stiff joints and moving bone structures can cause noises but not pain. Sometimes, releasing a tight ligament also creates a popping noise, but discomfort can accompany it.

Crepitus

Age and overuse can cause the cartilage to deteriorate and bone spurs to develop. Due to these factors, the joint surfaces become rough. This problem causes crepitus, which refers to sounds like grinding and popping in the joints when moving.

When to See a Physician

Most of the time, popping sounds in your joints are normal and do not require treatment. However, you should see a physician if pain accompanies the noises or you have reduced mobility. For example, injuries like torn ligaments and tendons can lead to popping, followed by extreme aches and swelling. 

Other conditions requiring a physician's intervention include tendinitis and bursitis, which are types of inflammation that can cause cracking sounds, pain, and limited mobility. A joint immediately locking up after popping can also indicate a more serious injury.
