Is it normal for teenagers' knees to make noises when they squat and stand up?

Nowadays, some teenagers have some crackling noises in their knees when they squat or stand up. Many parents worry whether their children have a disease that causes the noise, or are suffering from calcium deficiency or other problems. But the reason is due to the friction of the meniscus inside the knee joint when bending, so it will not have any effect. Therefore, we explain this phenomenon accordingly and also learn some methods to reduce its occurrence.

1. Causes

This is called joint popping. Because when the joints move, there is friction between the articular surfaces, between the cartilage pads and the articular surfaces, between the tendons and the joint capsules, between the tendons and the bones, and between the tendons. Generally speaking, this situation is often caused by joint degeneration and strain. Usually, it is checked by taking an X-ray. There may also be a calcium deficiency. Pay attention to the usual maintenance. Don't overwork yourself or catch a cold.

Joint popping can be divided into physiological and pathological. Most of them are physiological and will not cause discomfort in other parts of the body. They are not harmful to the body and do not require treatment, nor is there any need to worry about them. However, some people experience uncomfortable feelings such as soreness, swelling, etc. when their joints pop, which may indicate that there is a problem with the joints. Some common clinical diseases include meniscus injury, patellofemoral joint osteoarthrosis, etc. The above symptoms may also be caused by long-term strain and cold of the knee joint.

(II) Solution

1. Calcium deficiency causes knee cracking. At this time, you can choose to take some calcium tablets to supplement calcium. The best way to improve this situation is through diet. You can eat more calcium-rich foods such as sesame paste, milk, dried shrimps and mustard greens.

2. Sitting for a long time causes knee cracking. If the joints are not moved for a long time, the production of lubricating fluid in the joints will be reduced, and the joints will suffer greater damage due to friction. Therefore, it is recommended that everyone should exercise frequently and do more exercise.

3. Knee noise is caused by damage to the meniscus or cartilage at the knee joint. If it is just a simple noise without any pain, there is no need to worry too much. Take good care of yourself, avoid standing and walking for long periods of time, and massage the knee joint more often. If the knee makes a sound and is accompanied by pain, it is recommended that you go to the hospital to consult a doctor and seek medical treatment in time.
