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 in young people it is mostly 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. For the future, we should learn to take care of our joints and choose the right treatment as early as possible. 1, symptomatic treatment Early, we can take oral analgesic and anti-inflammatory drugs, such as fentanyl, Intacrine and other drugs, with local heat, physical therapy, knee protection and other methods to obtain healing. 2. Minimally invasive surgery For patients with more serious recurrent attacks, the correct surgical treatment should be taken early. Nowadays, minimally invasive arthroscopic technology is widely available. Arthroscopic surgery only requires two small holes of chopstick thickness next to the patient’s joints, and the lesions in the joints can be easily treated with the help of instruments through the TV screen, and the patient can move around the next day after the surgery. This technique has been carried out in our hospital for 17 years and the results are quite satisfactory. 3.Joint replacement For serious joint disorders, artificial joint replacement surgery is a good choice. Our hospital has hundreds of knee replacement surgeries every year, and the joints can resume walking 3 days after surgery. 4, 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, pay attention to 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.
