What is the cause of knee joint swelling

The elderly should pay attention to their daily travel, because their bones are in a tendency to gradually degenerate, and if they are not careful, their bones may easily fracture and break. The area around the knee joint is the most prone to problems among the elderly, especially in elderly women. Some elderly people find that their knee joints are too swollen. So what are the causes of excessive swelling of the knee joints?

What causes knee swelling?

1. What causes knee swelling: rheumatism and rheumatoid arthritis

Rheumatism and rheumatoid arthritis are an important cause of knee pain, and patients often experience pain in joints such as the knees and wrists.

2. What causes swollen knee joints: gout

Knee pain caused by this reason can be divided into acute and chronic stages. It is mainly caused by eating seafood or drinking alcohol. Severe patients will experience joint deformities.

3. What causes knee swelling: femoral head necrosis

Femoral head necrosis is often accompanied by pain. The main manifestations of femoral head necrosis are limited hip joint function and tenderness at the midpoint of the groin, while some patients experience pain in the knee and inner lower thigh.

4. What causes knee swelling: fat filling of the knee joint space

Fat pad strain The fat pad fills the gap in the front of the knee joint, which strengthens the joint stability and reduces friction. The cause of fat pad strain may be due to trauma or long-term friction, which causes congestion, hypertrophy and inflammation of the fat pad, adhesion to the patellar ligament, and thus limits the movement of the knee joint. This type of injury often occurs in people over 30 who frequently walk, climb mountains, or squat. The patient will feel pain in the knee joint, which worsens when the knee is fully extended, but the joint movement is not restricted. Symptoms are obvious after exertion.

5. What causes knee swelling: 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 appear swollen and feel slippery, and there is a popping sound when the joints move.
