Knee feels swollen and painful

So far, many people have reported knee pain, swelling, coldness or "cold wind" after reaching a certain age. When they were young, they often wore shorts and caught cold, and had no awareness of protecting their knees. After a certain age, they are likely to suffer from knee joint problems. Inability to climb stairs, pain when walking, stiffness, swelling in the morning, occasional joint deformities, and friction sounds when walking are all manifestations of knee joint disease. If you encounter this situation, you need to go to the hospital for treatment immediately.

Many people think that this is what happens when you get older, but in fact it is a disease. An X-ray examination will reveal that it is caused by degeneration of articular cartilage. Bone hyperplasia, synovitis, meniscus injury and patellar softening are common clinical manifestations. However, since articular cartilage and meniscus are avascular tissues and lack blood supply, treatment is difficult.

Which type of knee disease do you have?

1. Joint degeneration: There is a smooth, flexible and elastic protective layer on the joint surface, which is medically called "articular cartilage". As we age, articular cartilage wears out and becomes thinner, losing its former smoothness and elasticity, becoming sunken or even falling off in small pieces (prone to bone hyperplasia, cystic changes and free bone), which is medically known as "joint degeneration";

2. Bone hyperplasia: After the articular cartilage degenerates, wears out and becomes thinner, and becomes sunken, the human body gradually grows bone spurs to maintain the stability of the joints. This is bone hyperplasia, commonly known as "bone spurs";

3. Synovitis: "Synovitis" is a disease in which joints are traumatized or lesions in the joints stimulate the synovium, causing congestion and edema of the synovium, excessive secretion of synovial fluid, and reduced absorption, resulting in joint edema and pain.

4. Meniscus injury: The meniscus are two crescent-shaped gaskets located in the gaps on both sides of the knee joint cavity. When the joint rotates violently, they tear, which is called meniscus injury. ;

5. Patellar softening: It refers to a disease in which the surface cartilage of the patella (kneecap) degenerates, corrodes, breaks, softens and falls off due to repeated sprains or unreasonable movements. Joint pain and fatigue are its main manifestations.
