With the onset of spring, the number of orthopedic outpatients with osteoarthritis has increased significantly. In particular, some middle-aged and elderly patients who have not suffered any injuries are experiencing joint pain, with the focus on the knee and hip joints. In fact, most of them suffer from osteoarthritis. After the age of twenty-two or three, the pituitary gland secretes less growth hormone and the body stops growing. All organs of the body enter a maintenance phase and begin to age, and the chondrocytes in the body also enter the maintenance phase from the active phase and then slowly age. Therefore, everyone can be a “backup” for osteoarthritis patients. Patients who feel pain in their joints are actually experiencing wear and tear of the cartilage in their joints, and the pain is caused by degeneration or exposure of the subchondral bone in some areas. Studies have proven that the pressure on the joints for each step a person takes when walking is equivalent to four times their own weight, so the greater the weight, the greater the pressure on the joints, and obesity is a major killer of the joints. Obesity tends to cause premature wear and degeneration of knee cartilage, accelerating the process of degenerative knee disease. There are also some details of life that can cause arthritis to come early if you don’t pay attention to them. For example, middle-aged and elderly people like to exercise and choose to climb stairs and play tai chi. When climbing stairs, the pressure on the knee joint is about three times the body’s own weight, and the knee joint is susceptible to knee osteoarthritis when it is under such pressure for a long time. Osteoarthritis needs to be treated early to avoid aggravation and delaying the best time for treatment.
