Today, orthopedic clinics are seeing more and more patients for joint pain, and although middle-aged and elderly people are still the most common, patients of all ages are becoming more and more popular. Why? Some people say that joints are prone to pain when it is cold, but why does it still hurt when it is hot? The root of the disease in middle-aged and elderly people is basically osteoarthritis (commonly known as proliferative arthritis) at work; while most young people have synovitis of the knee, chondromalacia of the patella, meniscal injury, cruciate ligament injury, etc. Many patients often do not take early pain seriously and try to endure the pain until it becomes unbearable, then they think of going to the hospital for examination, which does no good to the protection of the joints! This often leads to early aging of the joints. In order to have a good joint, we need to learn to maintain it and choose the right treatment means early. 1, symptomatic treatment Early, general joint inflammation, we can take oral analgesic, anti-inflammatory drug treatment, such as fen-phen, Ying Taiqing and other drugs, with local heat, physical therapy, knee protection and other methods to obtain healing. For patients with more severe recurrent episodes, correct surgical treatment should be taken early. Nowadays, minimally invasive arthroscopic techniques are widely available, and the surgery only requires two small holes as thick as chopsticks next to the patient’s joint, and the lesions in the joint can be easily treated with the help of instruments through a TV screen. Of course, for anterior and posterior cruciate ligament ruptures of the knee, special attention should be paid. It is best to perform an arthroscopic cruciate ligament reconstruction surgery, in which one’s own tendons are selected for braided sutures and the damaged ligaments are rebuilt by drilling holes in the bone to restore stability to the knee joint. For severe joint disorders, timely arthroplasty is a good option for early relief of pain and walking difficulties. Our hospital has hundreds of knee replacement surgeries every year, and we can resume walking on the ground 3 days after surgery. 2, joint maintenance First, avoid a posture for too long, such as sitting for a long time, squatting. Because bad posture will only increase the load on the joint, resulting in cartilage metamorphosis and hyperplasia. Second, focus on the functional exercise of the joint. A simple and easy way is to sit or lie down when the joint flexion and extension activities, and then is to choose the appropriate intensity of exercise, such as walking, bicycling, etc.. Try to avoid high-intensity exercise, such as climbing, climbing, up and down stairs exercise and other activities, these activities will increase the load on the joint and damage the joint, aggravating the inflammatory symptoms. Finally, timely supplementation of calcium and drugs to improve cartilage nutrition. Calcium supplementation is important. Eat more calcium-rich foods, such as eggs, dairy products, soy products and seafood. In addition, take some glucosamine drugs that promote cartilage growth.
