Is Joint Popping and Cracking Serious?

Do your joints make noise when you move? Knees, ankles, fingers, and shoulders can all make cracking or popping noise from time to time. While it may sound like something is terribly wrong with the joint, in most cases joint noise is nothing to worry about.

Crepitus is the medical term that refers to joint noises, such as popping and cracking and creaking, particularly in the knees.

Such joint noise can be quite disturbing and cause concern, especially when it shows up suddenly. In most cases, these noises are not indicative of any underlying problem. Most joint crepitus, cracking, and popping usually has a bark that is worse than its bite. Joint noises often persist for years without any significant problems developing.

In the knee, for example, cracking or popping may occur if the patella (knee cap) is slightly out of alignment, and rubs on the adjacent tissues. Other causes of joint noise are the snapping of tendons or scar tissue over a prominence or something referred to as cavitation. Cavitation frequently occurs in synovial joints when a small vacuum forms in the synovial fluid and a rapid release produces a sharp popping or cracking sound.

Any joint popping or cracking that is associated with pain may indicate damage to the articulating surfaces of the joint. Such pops, cracks, creaks, and clicks could be due to tissue damage, such as a tear in the meniscus of the knee, but are sometimes due to an overly large or loose meniscus which may snap over the other structures in the joint as the knee bends and straightens.

If you hear joint pops and clicks with no associated pain in a joint, you don't need to worry, but you may want to begin some conditioning exercises to improve the overall integrity of the joint. Stronger muscles will take the weight off of the joint and help reduce the pressure on the articulating surfaces.

If there is pain along with those joint noises, you may have signs of structural damage building in the joint. It would be wise to see a physician for an appropriate diagnosis and treatment pain to help prevent further damage.
