What is the reason for long-term leg joint pain

Leg joint pain is related to many factors. Many people don’t know what leg joint pain is. Except for occasional leg joint pain, you don’t need to worry about it. Long-term leg joint pain must be treated early. It may be closely related to some arthritis and rheumatism.

1. Fat pad strain

The fat pad fills the gap in the front of the knee joint, which helps to stabilize the joint and reduce friction. The cause of fat pad strain may be due to trauma or long-term friction that causes the fat pad to become congested, thickened and inflamed, and adhere to the patellar ligament, thereby limiting the movement of the knee joint. This type of injury often occurs in people over 30 who frequently walk, climb mountains, or squat. Patients will feel pain in the knee joint, which worsens when it is fully extended, but the joint movement is not restricted. Symptoms are obvious after exertion. Treatment is mainly conservative, combined with physical therapy and oral medication.

2. Meniscus injury

Meniscus injury is a common injury among athletes. When the lower limbs are weight-bearing, the feet are fixed, and the knee joints are slightly flexed, if the knee is suddenly excessively internally rotated or externally extended (for example, in volleyball, when a player suddenly turns around and dives to save the ball while defending), it is possible to cause a meniscus tear. Meniscus injury will cause an obvious tearing feeling in the knee, followed by joint pain, limited movement, and limping when walking. The joints show swelling and a feeling of slipping, and there is a popping sound when the joints move. Treatment depends on the severity of the injury, whether conservative or surgical.

3. Traumatic synovitis of the knee

The synovium of the knee is one of the main structures of the knee joint. Synovial cells secrete synovial fluid, which can keep the articular cartilage surface smooth and increase the range of joint motion. When the synovium is damaged due to trauma or excessive strain, a large amount of fluid will accumulate, increasing the pressure within the joint. If it is not eliminated in time, it can easily cause joint adhesion and affect normal activities. Patients will feel pain, swelling, tenderness in the knee joint, and a frictional and astringent sound in the synovium. The most obvious characteristic of pain is that when the knee joint is actively and extremely extended, especially when the knee extension movement is performed with a certain resistance, the pain below the patella will be aggravated, and the pain will also be significantly aggravated during passive extreme flexion.

4. Notes

Patients with leg and knee joint pain must pay special attention to keeping warm and not letting their legs get cold. It is recommended to eat a light diet and eat less spicy food. Pay attention to controlling your food intake, maintaining a normal weight, staying away from cold water, and avoiding excessive fatigue and mental stress.
