Reduce knee wear and extend service life? Orthopedic doctors share 6 maintenance "tricks"

The knee joint is the largest joint in our body, and its structure is also the most complex. The knee joint will experience corresponding wear and tear with age and frequency of use. If the knee joint is injured, the follow-up treatment is very long and complicated. Therefore, we should pay attention to maintaining the knee joint in our daily life and slow down the wear process of the knee joint. But before that, we should first understand the composition of the knee joint and its main role in order to better find ways to reduce the wear and tear of the knee joint.

I. Importance and composition of the knee joint

The knee joint bears the main weight of the human body and keeps the body in a state of balance. It is one of the important parts of a series of human activities such as jumping, running, and walking, and provides an important guarantee for human movement. The knee joint is composed of the lower end of the femur, the upper end of the tibia, and the patella. Due to gravity, the medial and lateral condyles of the femur and tibia are particularly wide, and the joint capsule is thin and lax. And in front of the knee joint, the patellar ligament formed by the quadriceps tendon is reinforced, and there is a collateral ligament on the side of the knee joint to protect the knee joint and prevent the knee joint from being suddenly impacted from the side during exercise. There are two cruciate ligaments in the knee joint called the cruciate ligaments. They connect the tibia and femur tightly and strengthen the knee joint from the middle. It was found by X-ray that among the tibial, fibular collateral ligaments and anterior and posterior cruciate ligaments, the first three ligaments were most closely related during activity. When the knee joint is fully extended, the fiber directions of the above four ligaments are parallel. At this time, if the joint is injured by external force, the first injury is the fibular collateral ligament, followed by the anterior cruciate ligament, and then the posterior cruciate ligament. This finding suggests that the ligaments mentioned above are intrinsically linked to syndesmotic injury during exercise. There are also a pair of meniscus cartilages made of fibrocartilage in the knee joint, the meniscus. They are concave and flat, with a thick outer edge and are connected to the sac. The appearance of the meniscus deepens the depth of the socket at the upper end of the tibia, making the joint more stable. The meniscus is also elastic, stabilizing the joint and cushioning shocks. The above content is the main composition of the knee joint and the importance of the knee joint in the human body. But the knee joint will wear out with age, degeneration of surrounding tissue and a lot of movement, and there will be "warning signs" before the knee joint is worn out. Let's find out together.

Second, "early warning signs" before the knee joint wears out

Usually, at the age of 15-30, the knee joint and its The surrounding tissue is in "perfect condition" and the movement is tireless and without major problems. However, in the age of 30-40, most people's patellar cartilage has undergone early mild wear and tear, which makes the knee joint feel sore, but this situation will not last for a long time. This is the "warning signal" that the knee joint sends out during this period. But because there is no nerve distribution in the patellar cartilage, it only sends a signal once before it wears down, and some people don't even notice it. During this period, it is necessary to avoid strenuous exercise, and the use of the knee joint after the age of 30 should not be careless. During the age of 40-50, it is easy to have soreness on the inside of the knee joint after walking a long distance, but it will be relieved after gentle. This signal may prompt people to degenerate the meniscus, because the meniscus has nerves that remind people to protect the knee joint through pain when it is damaged. After the age of 50, some people will experience significant pain in the knee joint, which is a signal that the patellar cartilage that makes up the knee joint is worn away, the full thickness of the cartilage is worn away, and joint disease has developed. This is to remind people to minimize the use of joints, reduce the movements of going up and down stairs and climbing mountains, and use crutches if necessary to reduce the pressure on the knee joints. When you find these early warning signs of the knee joint, you should start paying attention to the condition of the knee joint and protect your knee joint from all aspects of daily life. So what are the ways to reduce knee wear? Let's learn together.

Third, reduce knee wear and prolong service life? Orthopedic surgeons share 6 maintenance "tricks"

First of all, it is necessary to appropriately reduce the amount of exercise and avoid actions such as climbing mountains and stairs. People who usually participate in strenuous exercise should gradually reduce the amount of exercise after entering old age. Because the joints of the elderly are thin, strenuous exercise will increase the wear and tear of the knee joints. Because when climbing a mountain, the ground is uneven and has a certain slope, which increases the pressure on the patella and femur when walking, and repeated friction can easily cause knee joint synovial damage and fat pad congestion. Next, pay attention to changing your posture. Because long-term sitting or squatting work, the knee joint will be fixed in the same position for a long time, which is not conducive to the blood circulation of the knee joint. Therefore, after a long-term action, you should pay attention to walking back and forth, stretching the lower limbs or massaging the knee joint to prevent the blood circulation of the knee joint from being poor and causing the adhesion of the internal and external tissues of the joint. It can also strengthen the exercise of lower body activities. Usually do alternate squatting, standing up and other activities, so that the knee joint can be fully extended, rotated, and prevent the knee joint from being stiff. However, middle-aged and elderly people with knee arthritis should not practice squatting, because the contact area between the bone and joint surfaces increases during the squatting process, and the friction will also increase relatively, which will aggravate the development of knee joint inflammation. In addition, we must also pay attention to the warmth of the knee joint. Because the knee joint lacks the protection of muscle and adipose tissue, it is only a skinny part. Therefore, the knee joint heat is easy to lose, and the temperature will be lower than other parts. And because the articular surface is composed of cartilage tissue, there are few cartilage blood vessels and poor blood circulation. If it is stimulated by cold for a long time, it may constrict local blood vessels and reduce blood supply, thereby weakening the ability of cartilage metabolism and defense. Produce ischemia, resulting in knee joint synovitis and other diseases. At the same time, the knee joint is also afraid of moisture. Therefore, the elderly should try not to stand for too long in the vent, and do not wash the knee joint with cold water. If necessary, you can wear a knee pad to prevent the attack from the cold wind and aggravate the knee joint injury. We can also reduce the load on the knee joint by controlling our weight. Because the knee joint bears most of the weight of the human body, if the weight is too high, it will cause serious damage to the knee joint. Obesity has been shown to be a risk factor for knee arthritis in a study comparing degenerative changes in joint structure in people who did not lose weight compared with overweight or obese adults who lost more than 5-10 pounds. Significant relief. Therefore, reducing weight can reduce the load on the knee joint and prolong the life of the knee joint. In addition, you can also insist on soaking your feet every day to increase the use time of the knee joint. Middle-aged and elderly people can soak their feet in hot water for 10-15 minutes before going to bed. After drying the feet, rub the soles of the feet 60 times each. Because this can promote the blood circulation of the lower limbs and ensure the blood circulation of the knee joints. To sum up, all of the methods can effectively reduce the wear and tear of the knee joint. We can apply these methods in our daily life to better protect the movement of the knee joint, reduce friction and prolong the service life of the knee joint.

Extended reading: Is a severely worn knee a "knee replacement" or a "knee protection"?

Many people think that the knee joint can only be "exchanged" if the knee joint is severely worn. But is this the case? Is there any other workaround? For patients with early stage knee joint disease, conservative treatment is usually adopted. You can take non-steroidal anti-inflammatory drugs or physical therapy, rest and other methods to relieve pain. When taking medicine, you should be under the guidance of a doctor, and you should not take it blindly. However, in addition to artificial knee replacement, patients with severe disease also have "knee preservation" methods. Knee preservation is to preserve the patient's knee joint, and treat knee joint diseases through fibula amputation surgery and medial fibula osteotomy combined with implantation of balanced absorbing spacers. Although "knee replacement" surgery has been developed for decades and has become very mature, knee replacement surgery requires a lot of osteotomy, large trauma, high price, long recovery time, and many postoperative complications. Knee joint prostheses are also used to some extent. Longevity, knee replacement surgery is not recommended. The "knee-sparing" surgery can preserve the knee joint, improve knee function and relieve pain at the same time. The "knee protection" program is less invasive and less risky, and can ensure that the patient recovers in a short time, and the knee joint function basically returns to normal. However, this regimen is not suitable for patients with unstable joints and lax ligaments. Therefore, when choosing a surgical plan, you must follow the doctor's advice and choose the treatment method that suits you. References: [1] Zhang Yingze. Knee replacement or knee protection [J].
