[Fan Letters].Zhang Jing is a typical Chinese mother who has devoted her life to her family. However, the years did not forgive, and the years of housework put too much burden on her knees, which eventually led to knee arthritis. Zhang Jing, who was in unbearable pain, was forced to be hospitalized**.
During her days in the hospital, Zhang Jing's biggest wish was to see her son Xiaojie come to the hospital to visit her. But when Zhang Jing dialed ** and hoped that her son could come to the hospital to accompany her, Xiaojie always refused on the grounds that he was busy with work.
At the same time, Zhang Jing's son-in-law, Li Qiang, became her main companion in the hospital. Li Qiang is an ordinary clerk, but his care and care for Zhang Jing is meticulous. Every day after work, Li Qiang always showed up at the hospital on time, chatted with Zhang Jing, helped her massage her painful knees, and even gave up his rest time to take care of her.
Over time, Zhang Jing's condition improved and she was finally able to be discharged from the hospital. Her deep disappointment in her son is intertwined with her son-in-law's gratitude. On the day she was discharged from the hospital, she decided to give Li Qiang 100,000 yuan to express her gratitude for his selfless care during this time.
After the news spread, his son Xiaojie suddenly became "free". He began to visit Zhang Jing frequently, and even offered to help her better. Zhang Jing knew in her heart that Xiaojie's sudden concern might be related to the money she gave to her son-in-law.
[The doctor answers].The knee is one of the most important joints in our body, and it bears a lot of pressure to support our weight and movement. However, as you get older or due to other health problems, your knees may develop some abnormalities that make you feel uncomfortable or unstable when walking. This article will ** the phenomenon of the knee suddenly "softening" when walking, and list three possible abnormalities to help you better understand knee health problems.
1. The basic structure and function of the knee
In order to better understand knee problems, it is first necessary to understand the basic structure and function of the knee. The knee is a complex joint made up of the femur, tibia, and patella. It has structures such as joint capsules, ligaments, meniscus, and muscles that work together to achieve the following functions:
Supporting Weight: One of the first tasks of the knees is to support our weight. Imagine that whenever we walk, run, stand, or do any weight-bearing activity, our knees are constantly subjected to gravity from the mass of our body. This means that it must have enough strength and stability to cope with this tremendous force.
Bend and straighten: Another important role of the knee joint is to allow our legs to bend and straighten freely. This ability is fundamental to walking, running, jumping, and performing a variety of daily activities. Whenever we take a step, go up or down stairs, or do physical exercise, the bending and straightening function of the knee plays a key role.
Impact Absorption: Not only that, but the knee also has an excellent ability to absorb impact. Its structure and soft tissues can effectively reduce the transmission of impact forces on the ground to our bones and other joints, thus reducing the risk of injury. This feature is especially important, especially during high-intensity sports or jumping activities.
Stability: The stability of the knee is not only dependent on its own structure, but is also affected by the synergistic effect of the surrounding muscles, ligaments, and meniscus. Together, these elements ensure the stability of the knee in motion, preventing it from losing stability in an inappropriate situation. This stability is essential to avoid sprains, ligament injuries, and other knee problems.
2. There are three possible abnormalities in the knee that suddenly "softens".
When you walk, if your knee suddenly feels "soft", it could be a sign of one of three anomalies:
Meniscus Injury:
The meniscus is a cartilage structure within the knee that helps reduce pressure and stability on the joints. Meniscus injuries are usually caused by a sharp twist or impact, causing the knee to suddenly "go soft" with pain and swelling. This condition may require physical**, anti-inflammatory medications, or surgery**.
Anterior cruciate ligament injury:
The anterior cruciate ligament is an important ligament that connects the femur to the tibia and is used to stabilize the knee. Injuring the anterior cruciate ligament usually occurs during strenuous exercise or falls, resulting in instability and a "soft" feeling in the knee. This can include physical, surgical, or other, depending on the severity of the injury.
Cartilage wear: Knee cartilage may wear down with age or chronic overuse. This condition leads to increased friction on the joint surface, making the knee feel uncomfortable and "soft". Knee cartilage wear and tear may require medical**, physical**, or arthroscopic surgery to reduce symptoms.
3. How to protect knee health
In addition to abnormal conditions, it is also very important to protect the health of your knees. Here are some ways to do it:
Maintain the right weight: Losing excess weight can reduce additional stress on your knees and reduce the risk of knee problems.
Do moderate exercise: Regular exercise can strengthen the muscles around your knees and improve joint stability. Choosing low-impact sports, such as swimming or cycling, can reduce the impact on your knees.
Strengthen knee muscles: Specific muscle-strengthening exercises, such as leg lifts and knee extensions, can help support the knee joint.
Pay attention to your position: Proper positioning is essential in daily activities. Avoid sitting with your legs crossed or staying in the same position for long periods of time.
Proper rest: If your knee feels pain or discomfort, timely rest and ice can help reduce symptoms.
The knee is one of the most important joints in the human body, and any abnormality can have a negative impact on quality of life. If you feel a sudden "softness" in your knees while walking, don't ignore the symptoms. It is very important to consult a doctor as early as possible for proper examinations and **. Additionally, by maintaining a proper weight, moderate exercise, and good body position, you can help reduce the risk of knee problems and protect the health of your knees. Cherish your knees as they are your supporters as you move towards a healthy and active life.
