What's with the knee noise?

What's with the knee noise? Knee noise is generally divided into physiological snap and pathological snap. Physiological sudden onset is not accompanied by pain, but a normal physiological change. Pathological snapping up is usually accompanied by pain, redness and swelling. And it is necessary to go to the hospital to find out the cause for treatment. Let's take a look at what physiological snapping and pathological snapping are ~

1, physiological snapshot

The so-called physiological burst is simply "normal". When we move the knee joint, the tiny bubbles in the joint fluid will burst with the change of joint pressure and produce sound. Physical snapping hardly brings pain and discomfort. For example, when we suddenly throw our legs or squat, our knees will make a noise, but there is no discomfort. This is mainly a physiological reaction. Because it is a normal phenomenon, there is no need to worry.

2. Pathological fracture

The so-called pathological snapping, that is, when the joints snap, will be accompanied by pain and swelling, suggesting that the joints may be pathological damage. The reasons for pathological snapping up are: Meniscus injury, knee joint inflammation, hyperosteogeny, etc.

1. Meniscus injury: Due to traumatic injury or degenerative injury, the meniscus is frequently stimulated, resulting in friction load beyond the normal physiological range, resulting in walking noise and pain.

2. Osteoarthritis of knee joint: inflammation caused by long-term bacterial infection or long-term strain will lead to swelling and pain of tissue.

3. Bone hyperplasia: With the increase of age, bone joints degenerate and ligaments around joints relax. Joints increase the stability of joints through hyperosteogeny. After a long time, friction will cause pain.

There may be other reasons for loud walking and pain in the knee. It is suggested to go to the hospital in time, improve the examination and clarify the cause, and standardize the treatment under the guidance of a doctor.

How to protect your knees scientifically?

1, early attention should be paid to weight control, because some people are heavier, which will inevitably increase the burden on the knee joint, and reducing weight is also a kind of protection for the knee joint. How to control it? Reasonable diet+scientific exercise.

2. Avoid squatting up and down stairs repeatedly, strengthen muscle training, and strengthen muscle training of quadriceps, hamstring and triceps surae around the knee joint. Only by strengthening the leg muscles can the knee joint be better protected. Weight-bearing straight leg lifting training and squatting against the wall are all very good training methods.

3. If there is osteoporosis, it is recommended to supplement calcium. Pay attention to keep warm when the weather gets cold, and wear cushioned shoes during exercise to protect your knees. In principle, it is a knee joint movement without load, such as riding a bike, swimming, or sitting on the sofa watching TV, you can lift your legs, put them down and repeat the exercise. This simple no-load exercise can protect the knee joint.

4. Reduce sedentary. The knee joint will constantly secrete synovial fluid during normal activities, and getting up and moving the knee joint from time to time can restore the tension of the body and supply energy to the cartilage.

5. Physical therapy after exercise. After daily exercise, in order to better protect your knees, you can carry out appropriate physical therapy, such as using ultrasound, which not only promotes blood circulation and metabolism; It can also relax muscles and relieve pain, and the protective effect on knees is still very good.
