What is the reason for knee joint pain

If people with knee joint pain want to effectively solve the problem, they need to focus on analyzing and understanding the causes, such as common joint synovitis, or some immune system diseases. Common lupus erythematosus and psoriasis may be the cause.

1. When the synovium of the joint is damaged by trauma or excessive strain, a large amount of fluid will accumulate, increasing the pressure inside the joint, leading to joint pain, swelling, tenderness, and friction and astringent sounds. For example, when the knee joint is actively and extremely extended, especially when the knee extension exercise is performed with a certain resistance, the pain below the patella will be aggravated. The pain is also significantly aggravated during extreme passive flexion.

2. Autoimmune system diseases Autoimmune system diseases such as lupus erythematosus and psoriasis can also affect the joints and cause swelling and pain, which require blood tests to assist in diagnosis.

3. Patients with growing pains in children are mainly children in the growth period, and boys are more common. The pain is commonly found in the knee joint, hip joint, etc. This situation is a normal physiological phenomenon that occurs during children's growth and development. Because the bones of children in the growth stage grow relatively quickly, the growth and development of the periosteum and local muscles are not coordinated, which causes discomfort and joint pain. It is also believed that the pain is caused by a low-grade infection.

4. Traumatic joint pain is caused by some kind of accident or incident that causes trauma to the joints of the shoulder, wrist, knee, ankle, etc. without any serious fractures (such as soft tissue injury, fracture dislocation, etc.), resulting in joint pain.

5. Septic arthritis has a history of infection in other parts of the body or a history of local trauma. The painful joints may be swollen, and the deep location may not be obvious, but there are symptoms such as increased body temperature, joint pain, inability to move, and increased blood count.

6. Osteoarthritis The onset of osteoarthritis is mostly after the age of 40. Joint pain is worse in the morning and gets better during the day and night. Bone hyperplasia and bone spurs in the joints rub against surrounding tissues, causing joint pain.
