The knee is a complex joint that experiences a lot of wear and tear. Knees are the most commonly injured joints, and the largest organ in the body is also the human knee. The knee joint is a complex unit that consists of bones, ligaments, tendons, cartilage and other tissues. The knee joint is surrounded by various tissues and fluid, which allows the knee to move in many directions.
There are four types of arthritis: Osteoarthritis, which affects the supporting cartilage of bones; Rheumatoid arthritis, an autoimmune disorder in which the immune system attacks joints; Gouty arthritis, a hereditary disease that causes joint tissue to swell and form uric acid crystals; and Septic arthritis, which occurs when bacteria invade a joint through a break in the skin.
Crane knee wind
The crane knee wind indicates the pain with heat sensation in the knee along with swelling. Ancient people called it crane knee wind since the swollen knee shaped like a bowl looking thin above and below. In east Asian medicine, it arises out of wind invasion and damp accumulation inside since water metabolism does not work properly.
The pain of knee usually arises when the joints are invaded by wind or water. The wind or water causes the water metabolism to become malfunctioning, which causes the dampness inside the joint to accumulate. Because the water metabolism is not working properly, the energy that should have been used up to keep the joint warm and moist is not being used.
