The knee joint is an important joint in human movement and is used in any situation. When the knee joint is subjected to greater weight, the risk of cartilage wear and tear also increases, and the tendons may be damaged, causing accelerated knee degeneration and causing great inconvenience to the patient's daily life.
When the knee is 20 years old, the carrying capacity of the knee is already formed. In order to protect their knees, people need to learn how to take care of them at different ages. The life span of the knee is different for men and women, and women should pay more attention.
01
What is the condition of the knee joint at different ages?
1. Before the age of 15
Before the age of 15, the body is in the stage of development, and the knee joint is also in the skeletal development.
Growing pains usually occur during adolescence, mostly near the knee joint, so special care needs to be taken to protect the knee joint.
2. 15-30 years old
The knee joint peaks in the age group of 15-30 years and is in "perfect condition" for long periods of exercise with little to no tiredness.
As long as it does not cause any damage, the presence of the knee joint can basically be ignored.
3. 30-40 years old
Early mild wear and tear of patellar cartilage over the age of 30 can cause transient knee soreness that lasts for weeks to months. Some people may not be aware of this.
Patellar cartilage is a layer of hyaline cartilage within the knee joint, with a thickness of 3 to 5 mm, which can cushion the impact of knee movement.
4. Over 50 years old
Middle-aged and older people over the age of 50 often experience knee pain, especially when going up and down stairs, standing or sitting.
Imaging tests can show problems such as bone and joint wear and bone hyperplasia, and in severe cases, joint deformities, leading to degeneration of the knee joint.

Knee pads for different age groups are emphasized
1. Adolescence
During the growth and development period, attention should be paid to controlling the amount of exercise and avoiding joint damage, and generally in the young age when the pain is reduced and the joints are in the best state, attention should be paid to controlling the amount of exercise and avoiding joint damage.
2. Middle age
At this age, it is best not to do strenuous exercise, pay attention to weight control, and take warm measures to protect the joints.
A sudden increase in exercise can cause pain and swelling within the knee joint, which can usually be relieved by rest, immobilization, and a combination of physical therapy and massage.
3. Old age
When the joints degenerate in the elderly, crutches may be used to reduce the pressure on the knee joint. For the elderly, when the joint is found to be degenerating, it is recommended to use crutches to reduce the pressure on the knee joint and reduce the risk of accidental falls, thereby delaying the injury and prolonging the life of the knee joint.
Therefore, if you want to protect your knees, you must learn how to take care of them!

How to protect the knee joint, 5 things to do well
1. Pay attention to your lifestyle habits
Clinical observations have shown that the number of women is higher than that of men in patients with knee disease. One of the important reasons for this phenomenon is that women squat more often for long periods of time throughout their lives, and both squatting and kneeling can cause greater damage to the knee joint.
Therefore, the action of squatting or kneeling for long periods of time should be avoided, and squatting for housework or kneeling to mop the floor should be avoided. Elderly people who like to practice Tai Chi should not bend over excessively, and can choose to stand and play high Tai Chi.
After a long squat, you should bend your knee slightly a few times before standing up before standing up, which will help protect your knee joint.
2. Avoid falling
Patients with joint pain or instability should be especially careful to avoid falls during daily walking, as this may further damage the knee joint. To avoid falls, make sure your home is well-lit, install stair handrails for going up and down stairs, and consider changing the squat toilet to a seated one.
3. Retain weight health
Since the knee is the part of the body that bears weight, too much weight can put more stress on the knee joint. Especially when going uphill and downhill and standing, there is a sudden increase in pressure.
If you are overweight, your knees will be put under a greater strain. Therefore, maintaining a healthy weight is key to preventing knee pain.
4. Eat more foods that contain a lot of calcium
Increasing calcium intake can effectively protect the health of the knee joint, and food should be the main way to supplement, and attention should be paid to maintaining balanced nutrition.
Eat more dairy products (e.g. fresh milk, yogurt, cheese), soy products (e.g. soy milk, tofu, bean curd, etc.), vegetables (e.g. carrots, bok choy, rape) and seafood such as seaweed, kelp, shrimp and fish.
In addition, spending more time in the sun can help promote calcium absorption.
5. Strengthen warmth
The blood supply to the articular surface, which is located in the knee area, is insufficient.
In cold conditions, blood vessels constrict and blood supply decreases, which affects the growth of joint cells and increases the risk of developing arthritis.
In summer, even in an air-conditioned room, you should pay attention to keeping your knees warm. In winter, it is necessary to wear enough clothing to ward off the cold, otherwise it is easy to cause rheumatism and other diseases, resulting in knee pain.
Write to the end
The knee joint is very important for people, so take good care of it. Take care of your knee joints, and the sooner you start, the better. Doing the above points can effectively prevent knee pain.
If you already have knee pain symptoms, you should pay more attention to the protection of your knees in your life. It is particularly important to correct the bad habit of injuring the knee joint, do a good job in the maintenance of the knee joint, and prevent the appearance of osteoarthritis.
