The doctor reminds: these 4 things are 'punishing' the knee, I hope we can realize it sooner!

A young white-collar Xiao Ruan came to the hospital's orthopaedic department. She told the doctor that her knee had never been injured, but recently she always felt inexplicably weak in her knee, and sometimes it hurts when going up and down the stairs. After examination and combined with MRI, the doctor found that Xiao Ruan's knee meniscus had been damaged.

This is strange, since there is no trauma, how can there be knee injury?

It turns out that Xiao Ruan is a high-heeled shoe controller. All the shoes at home are high-heeled shoes. She wears high-heeled shoes to work every day, causing damage to the knee joint...

The health of the knee joint can directly affect the quality of life, so do you know how to protect it?

As the largest and most complex joint in the human body, the function of the knee joint is also very complex, and in order to adapt to complex functions, the structure of the knee joint is also very complex. Among the many functions, weight-bearing and flexion and extension are the most basic and most important functions of the knee joint: the former refers to the knee joint bearing weight to complete walking, running, etc., while the latter refers to squatting, standing up, and going up and down stairs. .

The health of the knee joint affects clothing, food, housing, and transportation, but many people have suffered various injuries to the knee joint because they have not properly protected their knees. There are three common ones:

Meniscus injury: The meniscus has the function of increasing the depression of the tibia and ankle, strengthening the stability of the joint, and buffering the knee from external shocks. Therefore, the meniscus moves with the movement of the knee joint, when we flex the knee, the meniscus moves backward, and when we extend the knee, it moves forward. When the meniscus is injured, the knee joint will make noise when moving, resulting in limited knee joint movement and even knee joint pain. Meniscal injuries are often caused by joint instability, and when the ligaments in the joint are damaged, the meniscus can also be damaged. Therefore, if the knee ligaments are damaged, an MRI needs to be done in time to diagnose whether there is a meniscus injury.

Ligament injury: There are ligaments on both sides of the knee joint, which are divided into the medial collateral ligament and the lateral collateral ligament. When the knee joint is fully extended, the medial collateral ligament and the lateral collateral ligament will be in a state of tension, and the joint is stable. Abnormal control of maintenance and direction; and when the knee joint is flexed, the ligaments are in a relaxed state, the joint is unstable, and the knee is prone to injury. Therefore, when the knee joint is overextended or flexed, it is easy to cause ligament damage and affect normal activities.

Joint dislocation: The so-called joint dislocation, also known as "dislocation", refers to the loss of the normal position of the upper and lower bone ends of the knee joint, resulting in a dislocation. Joint dislocations are often caused by violent effects, such as sprains, which can cause pain in the knee joint and interfere with normal activities. Joint dislocation not only causes sprains of soft tissues such as ligaments and muscles, but also may cause problems such as hematoma around the joint.

The health of the knee affects our health. However, many people in life are doing things that hurt their knees, but they don't know it.

Excessive exercise: Even though exercise is good for your health, if you climb a lot of mountains and stairs for a long time, it will bring damage to your knees. When exercising in a scientific and appropriate amount, the wear and tear of the knee joint can be neglected, because the pressure stimulation at this time brings "nutrition" to the cartilage tissue, but if excessive exercise, especially mountain climbing or stair climbing, causes the knee joint to continue The movement of flexion and extension will not only stimulate cartilage wear, but also cause the synovium to secrete synovial fluid, causing acute synovitis and other diseases.

Sudden braking when running, or exercising without warm-up: Studies have shown that if you start exercising without sufficient warm-up, it is easy to cause problems such as tendon rupture. Therefore, without warm-up, the muscles around the knee joint The ligaments are not hot and are in a relatively stiff state, which is very vulnerable to injury. In addition, if you suddenly brake suddenly when running, it may also cause damage to your knees. This is equivalent to a car galloping on the highway, suddenly braking suddenly, which is very easy to cause accidents.

Wearing high-heeled shoes: For many women, wearing high-heeled shoes seems to have become an inseparable part of life like three meals a day. However, just like Xiao Ruan, who appeared at the beginning of the article, she often wears high-heeled shoes, causing knee pain. Joint damage. When wearing high-heeled shoes, the key forces on the knees and ankles are not balanced, which not only easily sprains the ankles, but also easily damages the knees. In severe cases, it will also cause damage to the meridians and bones.

Obesity: Researchers from the American College of Orthopaedic Surgeons conducted an in-depth study of elderly patients with osteoarthritis and found that patients with higher weight values ​​had more severe knee pain. They said that for every kilogram of weight gain, the load on the knee joint increased by four kilograms. Therefore, obese people are more likely to develop joint diseases such as osteoarthritis.

For the sake of knee health, we should actively carry out knee pad actions!

Leg-raising exercise: Doing the leg-raising exercise every day can strengthen the quadriceps femoris and biceps femoris of the thigh, strengthen the stability of the knee joint, and slow down the wear and tear of the knee joint, which is very beneficial to the knee.

Pay attention to keep warm: Since there are no abundant muscles around the knee joint, the blood flow of the knee joint is prone to slow down and muscles contract under the stimulation of cold. As a result, the protective effect of ligaments and muscles on the knee joint will be reduced. Long-term exposure to cold is also a joint disease. a major incentive. Therefore, be sure to do a good job of keeping the knee joint warm, and wear knee pads when the weather is cold.

Pay attention to the warm-up exercise before exercise: Warm-up exercise can improve muscle elasticity, enhance ligament elasticity, and avoid joint damage. If you ignore the warm-up exercise and start exercising directly, it is easy to cause joint or ligament strain, and may also cause dizziness, nausea and other uncomfortable symptoms .

Weight control: The knee is a weight-bearing joint. If the knee is too fat, it will increase the load and increase the incidence of joint wear and tear. If the body fat is too high, it will also promote inflammation, resulting in osteoarthritis. Therefore, for knee health, be sure to control your weight.

The health of the knee has a profound impact on us. In life, we must avoid the bad habit of hurting the knee, and use more knee pads to have a healthy knee joint!
