When running, my knee suddenly clicked. Why does the knee make a sound?

In the past two years, national fitness has become a craze. Many people choose to get up early or jog at night. When running, their knees suddenly clicked. Why does the knee joint make a sound?

Normal phenomenon. When people are active, it is normal for their joints to make some noise. At the same time, the joint activity is not affected, and there is no feeling of pain, indicating that the joint is just normal.

Combined gas. We know that there is joint fluid in the joint, and there are gases such as oxygen, nitrogen and carbon dioxide in the joint fluid, so when we are active, the joint is squeezed, and the gas will be squeezed out, thus making a sound.

Tendon activity. There are tendons in human body. When exercising, the tendon will move from the initial position to another position and then move back to the initial position. In the process of this tendon activity, a certain sound will also be produced.

Wear of patella. Some people's patella is injured and worn, so people's joints will make a noise when they are moving, and the click will be even louder when they are seriously worn. People with worn patella need timely rest or treatment.

Meniscus injury. We know that there is a meniscus in the knee joint. When the meniscus is damaged, people will hear the knee click when running. At this time, you need to rest in time to avoid the aggravation of meniscus injury.

In short, my knees make a noise when I run. If there is no pain, it is normal. If the knee makes a noise, feels limited activity, and is accompanied by pain and discomfort, it may be injured and needs to be checked and treated in time.
