If your knees crack, pop, or make crunching sounds when you move, you’re not alone. These noises, often described as “knee crepitus,” are surprisingly common and can happen to anyone, especially as we age. While knee crepitus is often harmless, it’s essential to understand when it might signal a deeper issue. Let’s explore what crepitus is, what causes it, and how you can address it to keep your knees healthy and strong.
Knee crepitus refers to the sounds your knees make when bending, straightening, or walking. This phenomenon can include popping, cracking, or crunching noises. Most people experience these sounds occasionally, and in many cases, they’re harmless. However, persistent or painful knee crepitus could indicate an underlying issue requiring attention.
The key to understanding knee crepitus is knowing the difference between normal and concerning noises. If your knees crack without pain, it’s likely due to natural changes in your joints as you age. But if you’re experiencing knee popping and pain, or if your knees make a crunching sound during everyday activities, it’s time to seek professional advice.
