Have you ever noticed a popping sound in your joints when you move? This phenomenon is known as crepitus, and it’s common for many of our in-home personal training clients in Toronto, Collingwood, and Hamilton, (and virtual personal training clients everywhere). While it can sometimes be alarming, crepitus is usually nothing to worry about. That said, in some cases, it can signal an underlying issue that requires more attention.

Why Do Your Joints Pop?

CREPITUS: THE BASICS

Crepitus refers to the sensation or sound of cracking, clicking, grinding, or popping when you move a joint. “Crepitus can happen at any age, but it is more common as people get older” (Medical News Today, 2023). It is sometimes accompanied by pain or discomfort, but in many cases, it occurs without any other symptoms.

CAUSES OF CREPITUS

Crepitus happens for several reasons. First of all, “small bubbles of gas can collect in your joints and cause cracking sounds when you move too quickly. This sound is known as cavitation. Cracking your knuckles is another example of cavitation. This type of noise is harmless” (Web MD, 2024). Secondly, tendons or ligaments may snap over bony structures, which also creates a clicking or popping sound. Finally, over time, the cartilage that cushions your joints can wear down, leading to rough surfaces that create a grinding sensation.

WHEN TO INVESTIGATE

If crepitus is accompanied by pain, swelling, or reduced range of motion, it may be due to an injury or underlying issue. “Crepitus is one of the symptoms of osteoarthritis, so your doctor will want to check whether or not you have any other signs of this condition” (Healthline, 2024). A history of injury to the affected joint is also a red flag.

You should always tell your in-home or virtual personal trainer if you’re experiencing pain during a workout. Exercise should be challenging at times – but never painful. A healthcare provider and an experienced trainer with an understanding of movement mechanics can help you determine whether modifications to your exercise routine are necessary.

MANAGEMENT

If crepitus is becoming an issue for you, building strong muscles around your joints can provide better support and reduce stress on cartilage. A proper warm-up before workouts is key, and lower-impact activities can maintain joints without excessive wear and tear.
