Knees are always clicking, but they are not swollen or painful. Is this normal?

Most people make noise when they experience knee joint activities. Many people lament that they are old and even worry that their knees will get sick. The knee joint is the largest joint in the human body, with the most complicated structure and the greatest chance of injury. It will be worrying if it is abnormal. But this does not mean that knee strike is a knee joint disease.

Does the "cracked" knee indicate that there is something wrong with the knee joint?

Knee click or physiological elasticity. Especially when you suddenly stand up from the squatting position, your joints will suddenly make a crisp sound, so don't worry too much if you don't feel pain. The joints are slippery, so there is a little foam in the lubricating fluid of the joints. Normally, bubbles dissolve in the synovium of joints. When the joint changes its bending angle, bubbles will be squeezed and escape from the synovium, resulting in large bubbles. When bubbles burst, they make a sound. In this case, no special treatment is needed.

What happened to the knee bullet?

1, articular cartilage wear

It is an important structure to have articular cartilage on the joint surface, and the articular cartilage is smooth and elastic. The thickness of articular cartilage is very large from infancy, but it will gradually become thinner with age. People's use, strenuous exercise, weight gain, trauma and other factors will lead to smooth cartilage wear, rough surface, articular cartilage surface cracking and falling off. You can hear obvious clicking sound when flexing and stretching joints, especially when going up and down stairs or crouching, accompanied by severe pain. It is necessary to go to the hospital for MRI of the knee joint in time to check whether there is cartilage wear in the joint. Under the guidance of a doctor, intra-articular administration of glucosamine or injection of sodium hyaluronate can promote the recovery of intra-articular cartilage injury, inhibit inflammation and relieve symptoms.

2, meniscus injury

Meniscus is an important cartilage structure of knee joint. When the joint bends, the shape will change to adapt to the knee joint, stabilize the joint, make the joint smoother, and at the same time play a buffering role and reduce the impact force such as running and jumping. With the increase of age, the meniscus wears and breaks, and there will be obvious pain and snapping when the joint bends. In this case, joint MRI should be done to see the degree of meniscus injury and choose the appropriate treatment according to the degree of injury. In meniscus tear's case, arthroscopic surgery is needed to restore the stability of the meniscus after suture.

3, joint ligament thickening

Thickening of joint ligaments occurs in people who like sports. Long-term exercise stimulates the ligaments around the joints, and small fractures will occur over time. Aseptic inflammation and scar formation lead to ligament thickening and surrounding soft tissue stimulation. Therefore, when the joint is stretched, the thickened ligament will rub the surrounding tissues or bones, resulting in projectile and pain. Usually pay more attention to rest, rational use of non-steroidal anti-inflammatory drugs or receive shock wave treatment to relieve symptoms.

How to protect knee joint?

1, to prevent wrestling and conflict;

2. Adjust the weight to reduce the burden on the knee joint.

3. Warm up before exercise.

People who sit in the office for a long time should take time to walk or straighten their legs every 30 minutes and do some simple knee pads.

5. Sit on the floor, bend one leg, open your palm, grab it below the knee, wrap the calf, press your thumb from the back to the back of the calf and push it down to maximize your strength.

65438 05 times were performed in each group. This action can improve the blood circulation near the knee joint, effectively improve the knee joint, improve the stability near the knee joint, and also have a certain effect on relieving pain.
