As the weather gradually warms up in March, it’s time to go out and explore the greenery. However, it is important to note that the early spring is a time of warmth and cold, especially in Shanghai, where we have a lot of rain, large temperature differences and high humidity, making it an easy time for rheumatic joint disease. Among the reasons for these patients, osteoarthritis is the most common. Osteoarthritis is a degenerative joint disease, also known as proliferative arthritis, or “bone spurs” or “osteophytes” as they are often called, and is most commonly seen in the knee joint. According to statistics, the incidence of osteoarthritis increases with age, with a prevalence of more than 50% in people aged 6O-75 years. As a chronic disease, osteoarthritis is prolonged and gradually worsens, affecting not only the quality of life, but even disability in severe cases, so once symptoms such as knee swelling, stiffness and pain appear, prompt medical attention should be sought. For osteoarthritis, there are several treatment methods. The first is patient self-prevention and health care, which is effective for most patients with mild to moderate osteoarthritis. For example, to prevent cold and keep warm, you can wear protective equipment such as knee pads when you go out for exercise; moderate exercise, choose the exercise method that suits you. For patients with osteoarthritis, you should try to avoid strenuous exercises such as running and hiking, and instead choose exercises that are less burdensome to the knee joint such as swimming and walking. Next is medication. For patients with more obvious symptoms of joint pain, medications such as anti-inflammatory and pain-relieving drugs, oral cartilage nutrients, joint cavity injections of sodium hyaluronate to lubricate the joint, and joint cavity injections for swollen and painful joints can be considered. Finally, patients for whom conservative treatment is ineffective may further consider the option of surgical treatment. For patients with acute synovitis or complications of free body or meniscal damage, minimally invasive arthroscopic joint cavity cleaning surgery is feasible to give the joints a major cleanup, thereby relieving pain and delaying joint destruction. For patients with advanced osteoarthritis with severe joint pain and ineffective conservative treatment, artificial joint replacement is the best choice. Artificial joint replacement is regarded as a milestone in the development of orthopedics in the 20th century and is a salvage treatment for advanced joint lesions, which can immediately relieve and eliminate joint pain and restore joint mobility.
