My Knee Cracks When I Bend It: Causes, Symptoms, and Treatment Options

Knee cracking, also known as crepitus, is a common phenomenon that many people experience when bending their knees. While it can be alarming and uncomfortable, in most cases, it is not a cause for concern. However, understanding the underlying causes, symptoms, and potential treatment options can help you address any discomfort or prevent further damage. In this article, we will explore the reasons behind knee cracking and provide answers to 14 commonly asked questions.

Causes of Knee Cracking:

1. Gas bubbles: The most common cause of knee cracking is the release of nitrogen bubbles from the synovial fluid within the joint. This is similar to the cracking sound made when cracking your knuckles.

2. Cartilage wear and tear: Over time, the cartilage in the knee joint may deteriorate, resulting in the roughening of the joint surfaces. This can lead to cracking sounds when the knee moves.

3. Ligament or tendon changes: In some cases, knee cracking may occur due to changes in the ligaments or tendons surrounding the joint. This can be caused injury, inflammation, or overuse.

Symptoms Associated with Knee Cracking:

1. Audible cracking or popping sounds when bending or straightening the knee.

2. Sensation of grinding or crunching within the knee joint.

3. Mild discomfort or pain accompanying the cracking sound.
