Knee Articular bone mostly occurs in middle-aged and elderly people, mostly women. The Chief physician of the Department of Orthopaedics of the Affiliated Hospital of Tianjin Central Research Institute reminded the army that women should pay more attention to the health of knee bones and joints to prevent knee Osteoarthritis. Articular bone of the knee is a chronic joint disease characterized by aging and degeneration of knee cartilage and Hyperostosis of the joint. Patients often come to see doctors because of pain, swelling or stiffness of the knee joint. Medical research found that knee Osteoarthritis is more common in middle-aged and elderly people, women are significantly more than men, the prevalence rate of women is 10.3%, and men is 5.7%. Women's knee Osteoarthritis usually starts at the age of 40, 10 years earlier than men. Why are women more prone to knee Osteoarthritis? Medicine believes that there are several aspects: women's pelvis is wider than men's, and weight acts on the knee joint through the pelvis, creating greater lateral stress and accelerating knee joint degeneration. Women's muscle strength is usually weaker than men's, and the muscles and ligaments provide poor protection to joints. Once bone and cartilage damage occurs, it is often difficult to repair. The reproductive process of women accelerates joint degeneration, leading to rapid weight gain during pregnancy, which increases the load on the knee joints and makes them prone to wear and tear. Hormone levels have an impact on women's bones and joints. Estrogen will suddenly decrease and decline after menopause, accelerating calcium loss and aging of bones and joints. How can women prevent and treat knee Osteoarthritis? The army gives four moves: first, proper exercise, including static contraction of Quadriceps, straight leg lifting, and static squatting against the wall. These exercise methods can increase the strength of the thigh muscles and provide good protection for the knee joint. Those who seldom exercise at ordinary times can start with non weight bearing exercises such as swimming and Core stability, and then slowly transition to weight bearing exercises. Pay attention to reducing knee joint injuries such as squatting and mountain climbing. The second is to control weight. Excessive weight can create direct pressure on the knee joint, which can increase the load exponentially when going up and down stairs or squatting. Maintaining good weight can slow down the aging rate of the knee joint. The third is a healthy diet, paying attention to balance. It is recommended to have a low oil, low fat, and low calorie diet, eat more fruits and vegetables, and control the intake of staple foods. Eat more high calcium foods. After the age of 50, calcium intake decreases due to factors such as decreased gastrointestinal function and body conversion function. It is recommended to pay attention to calcium supplementation. You can eat more dairy products, soy products, seafood, etc., and also bask in more sunlight to promote calcium absorption. The fourth is joint maintenance. Don't lose your "demeanor" and "temperature", it's important to keep your joints warm. With the growth of age, cartilage degenerates, and Glucosamine can also be taken orally to help nourish aging articular cartilage. (Outlook New Era Network)
