For a long time, many joint diseases have been troubling people and a tricky problem for doctors to treat. Probably everyone knows about rheumatism and rheumatoid arthritis and talks about it. When it comes to rheumatoid arthritis, everyone knows that it is difficult to treat, but did you know that? There are also many joint lesions that can cause people to lose their ability to work to a great extent, and also bring a lot of pain to everyone. This places a high demand on treatment. There are many ways to treat joint disease, including medication, surgery, functional exercise, physical therapy, joint fumigation, etc., but arthroscopic surgery has unique features and advantages among these methods. Arthroscopic surgery is minimally invasive surgery, called “surgery without surgery”, with a surgical incision of only 0.5 cm and one to three incisions, and the situation in the joint is reflected on the monitor through a computer system, so that the lesions in the joint can be seen at a glance. The development of arthroscopic surgery is one of the main signs of the maturity of minimally invasive surgery and is a specific application of high technology in the medical field. This technology has been well developed in major cities in China. Using this technology, sports medicine treatment centers have been established in major provincial cities such as Beijing, Shanghai, Tianjin and Zhengzhou. Arthroscopic surgery has been carried out in our city for nearly a year and has been widely praised for its advantages of small incision, less pain, less bleeding, less damage and faster recovery. In particular, many lesions in large joint areas, such as recurrent effusion and swelling in rheumatic and rheumatoid arthritis, septic arthritis, osteophytes and free bodies in elderly osteoarthritis, and joint sports trauma are excellent indications for arthroscopic surgery. It is even preferred by certain special groups of people, such as athletes, young ladies, the elderly, and pediatric patients. Arthroscopic technology is the material basis for the emergence of sports medicine and is one of the main examination and treatment methods in sports medicine. It is suitable for the examination and treatment of injuries in large joint areas and is the best choice for joint sports injuries, and the application of arthroscopic technology has enabled many injured athletes to return to the sports field. Firstly, because it causes very little trauma to the joints and does not damage the basic structure of the joints; secondly, because of its special therapeutic effects, it can sort out joint disorders, repair cartilage damage in joints, clean up debris from injuries in joints, rebuild joint ligaments, help rectify and fix fractures in joints, and other effects. With the development of society and the affluence of life, people’s pursuit of beauty has become more intense. The traditional joint surgery incision is about 10cm, especially for the knee joint, which can leave a particularly ugly scar, and for young ladies it means losing the patent of wearing a dress. With arthroscopic technology, however, women don’t have to worry about this unsightly wound because the incision is so small and unnoticeable. As our society ages, the elderly are becoming more and more of a concern. Most of the geriatric joint diseases are degenerative diseases, mainly osteophytes, intra-articular free bodies, degeneration of articular cartilage, unexplained joint pain and swelling, etc., which bring a lot of inconvenience to the daily life of elderly people. Most elderly people suffer from different degrees of cardiovascular and cerebrovascular diseases, and their tolerance level to diseases and surgeries is significantly reduced. Combined with the physical characteristics of the elderly, arthroscopy shows special advantages such as smaller incisions, less pain, less bleeding, less damage, and faster recovery. Another advantage of arthroscopic surgery is the treatment of pediatric joint disease. Because pediatric joints have narrow gaps and are not fully developed. While open major surgery bleeds more and causes heavier damage to joint cartilage and peri-articular tissues, arthroscopy has special instruments for pediatric patients, which can more fully reflect the advantages of small incision, less bleeding and less damage of arthroscopy. The application of arthroscopy, a new technology in clinical practice, has already brought gospel to the majority of patients with joint diseases, and it will play a great role in our city of Zhoukou, providing a reliable method for patients with joint diseases to relieve pain, slow down joint aging, and diagnose and treat unexplained joint swelling.
