Knee joint pain mainly refers to joint pain in the knee, which is also a very common disease. The cause of this disease is also complicated. It may be due to overexertion of the knee joint, leading to injury, or It may be rheumatoid arthritis or other reasons. We need to understand the cause so that we can prescribe the right medicine. So, what is the main cause of knee joint pain? How to relieve knee pain.

1. Causes of knee joint pain

1. Fat pad strain: The fat pad fills the gap in the front of the knee joint, which can enhance joint stability and reduce friction. The cause of fat pad strain may be that trauma or long-term friction causes the fat pad to become congested, hypertrophic, and inflamed, adhering to the patellar ligament, thereby limiting knee joint movement. This type of injury mostly occurs in people over the age of 30 who frequently walk, climb, or squat. The patient will feel pain in the knee joint, which worsens when fully extended, but joint movement is not restricted. Symptoms are obvious after exertion. Treatment is mainly conservative, combined with physical therapy and oral medications.

2. Meniscal injury: Meniscal injury is a common injury among athletes. When the lower limbs are weight-bearing, the foot is fixed, and the knee joint is slightly flexed, if the knee joint is suddenly excessively rotated internally or externally rotated to extend the knee, (For example, in volleyball, when a player suddenly turns around and dives to save the ball while defending), it may cause a meniscus tear. Meniscus injury will cause an obvious tearing sensation in the knee, followed by joint pain, limited movement, and walking limp. The joints exhibit swelling and slipping sensations, and there is a popping sound when the joints are moved. Treatment depends on the severity of the injury, whether conservative or surgical.

3. Traumatic synovitis of the knee joint: The synovium of the knee joint is one of the main structures of the knee joint. Synovial cells secrete synovial fluid, which can keep the joint cartilage surface smooth and increase the range of joint motion. Due to factors such as trauma or overstrain, damage to the synovium will produce a large amount of fluid, which will increase the pressure within the joint. If it is not eliminated in time, it will easily cause joint adhesions and affect normal activities. The patient will feel pain, swelling, and tenderness in the knee joint, and there will be a friction and astringent sound in the synovial membrane. The most obvious characteristic of pain is that when the knee joint is actively extended to extreme extents, especially when knee extension movements are performed with a certain resistance, the pain in the lower part of the patella will be aggravated, and the pain will also be significantly aggravated when passively extreme flexion is performed. Treatment is mostly conservative.

4. Knee osteoarthritis: This disease is more common in middle-aged and elderly people, mostly women. Overload is the main cause of illness. The knee joint will be swollen and painful, and sometimes there will be a friction sound when moving the joint. There may be a varus deformity of the knee with medial pain. Treatment depends on joint degeneration and whether to undergo joint replacement. Currently, joint replacement treatment for knee osteoarthritis is a relatively mature treatment method in the world.

5. Knee joint ligament injury: The stability of the knee joint is relatively poor when it is slightly flexed. If it is suddenly subjected to external force and causes valgus or varus, it may cause damage to the medial or lateral collateral ligaments. Clinically, medial collateral ligament injuries account for the vast majority. Taking this injury as an example, the patient will have a clear history of trauma, pain and tenderness on the medial side of the knee joint, and the pain will worsen when the calf is passively abducted. There will be swelling on the medial side of the knee, and ecchymosis will appear after a few days. Knee joint movement will be limited.

6. Cold: In daily life, most joint pain is not caused by trauma. Cold (especially persistent cold and huge temperature contrast) is the main cause of joint pain. With the development of society, people's aesthetics and living habits have undergone great changes, and people pay more attention to the beauty of form. Even in the cold winter, many people no longer wear thick cotton clothes, but try to reduce the burden on their bodies as much as possible to adapt to modern aesthetic concepts and the fast pace of life. But while experiencing the beauty, people have to pay the price of joint damage, because cold can cause muscles and blood vessels to contract, causing joint pain.

7. Improper exercise: Some elderly people like to climb mountains, but if they are not prepared or do too much exercise, it can also cause joint pain. In particular, people suffering from synovitis or osteoarthritis are more likely to suffer from the onset or aggravation of joint diseases. In mountaineering, when going down the mountain, the weight of the whole body is completely placed on one knee joint, and the pressure on the knee joint is several times that of standing normally. The same thing happens when people go up and down stairs.

8. Bad walking habits: For example, often wearing ill-fitting shoes or walking long distances in slippers or high heels will put the knee joint in an abnormal stress state for a long time, causing chronic damage to the knee joint, causing pain.

The above injuries that cause knee joint pain cannot be cured by daily care alone. Experts remind: If you have the above pain characteristics, you should ask a doctor for a clear diagnosis as soon as possible to avoid delaying the best time for treatment.

2. Relieve knee joint pain

1. Knee bending exercises

During the time when there is no illness, patients can often do knee bending exercises at home. , which can not only reduce the frequency of knee soreness, but also relieve pain.

For some patients with symptoms such as low back pain, knee bending exercises are very unsuitable , so the patient can perform effective exercises in the chair at this time. The patient can sit shallowly on a chair with a slightly higher surface, and then bend the knee of one leg, preferably so that the thigh and calf are at 90 degrees. Then straighten the other leg. At this time, note that the ankle should maintain a naturally bent position, but the heel should touch the ground and the toes should lift off the ground.

Lift the straight leg upward. At this time, be careful not to bend the knee. When the heel of the straight leg is about 10 cm from the floor. Stay still for 5 seconds and then slowly lower it. At the same time, rest for 2-3 seconds after landing with your heel. Repeat this 20 times.
