What causes knee pain?

Knee pain can be caused by a variety of reasons, and understanding these reasons can help us better protect the health of our knees. The knee joint is one of the most complex joints in the human body, bearing the weight of the body and various sports pressures every day, so it is easy to have problems.

Knee pain may be age-related. As we age, the cartilage in our joints gradually wears away, leading to osteoarthritis, a common cause of knee pain in middle-aged and older people. Imagine that the cartilage in our joints is like a cushion, and when it wears away, the friction between the bones increases, causing pain. This condition is particularly common in older people and may affect daily activities.

Sports injuries are also a common cause of knee pain. Whether it is running, jumping or other high-intensity sports, the knee may be injured due to overuse or sudden sprain. For example, ligament tears, meniscus injuries and other problems often occur in athletes. It's like the suspension system of a car. If it is not used properly, the parts may be damaged.

Being overweight also puts extra strain on your knees. For every kilogram of extra weight you carry, your knees will bear several times more pressure. This long-term stress may accelerate wear and tear on the joints, leading to pain. Imagine climbing a mountain with a heavy backpack on your back for a long time. Your knees will naturally feel overwhelmed.

Knee pain may also be related to other diseases, such as rheumatoid arthritis, gout, etc. These diseases can cause inflammation and pain in the joints. It's like a "war" inside the joints, and the immune system's attack causes unnecessary damage and pain.

There are some things we can do to relieve knee pain. Maintaining a healthy weight, exercising moderately, choosing the right shoes, and paying attention to exercise posture are all good ways to protect your knees. If the pain persists or gets worse, it is very important to see a doctor promptly. The doctor can determine the specific cause of the pain through a detailed examination and develop an appropriate treatment plan.

Hopefully, this information will help you better understand the causes of knee pain and take effective steps to protect your knee health. Remember, knee health is vital to our daily lives and deserves our careful care.
