As the standard of living of the general public has improved, sports have become part of daily life, and injuries to large joints such as knees, ankles, shoulders, elbows and wrists caused by sports are increasing. On the other hand, China has entered an aging society, and it is the wish of every one of us to care for the elderly and let them enjoy their old age peacefully, but diseases such as knee osteoarthritis and frozen shoulder have brought great pain to many elderly people and added a great burden to families. However, diseases such as knee osteoarthritis and frozen shoulder cause a lot of pain and add a great burden to families. Conventional joint surgery requires a large surgical incision and additional damage, and long hospital stays, high costs and slow post-operative recovery, causing many patients to stagnate in the face of treatment, and eventually delaying their condition and regretting it for life! Arthroscopic surgery is a major progress in the field of minimally invasive surgery in orthopedics, which consists of lens, light source, monitor, surgical instruments under the mirror, shaving system, etc. When doing arthroscopic surgery, only water is needed to expand the joint, the doctor makes two to three 4-6mm long incisions around the corresponding joint, and puts the arthroscope into the joint through one of the incisions, and the arthroscope is connected to the monitor through wires, so that the situation in the joint can be very clearly displayed. The arthroscope is connected to the monitor through a wire, so that the situation inside the joint can be displayed very clearly, and the surgical instruments can be inserted through another incision, so that the lesions inside the joint can be treated under surveillance, such as removing the bone that affects the movement of the joint, suturing the torn meniscus, reconstructing the intra-articular ligaments, and transplanting cartilage. It can be seen that arthroscopic surgery, like other endoscopic surgeries, does not require extensive exposure of the joint, so it is naturally less invasive than incisional surgery, less bleeding, less painful, less complications, quicker recovery, earlier release from bed, and significantly shorter hospital stay and correspondingly less hospitalization costs. Moreover, the small incision also eliminates the fear of scarring that many female patients have after surgery and makes them more receptive to surgical treatment. In addition, because of the short hospital stay, it can solve the difficulties of many young and middle-aged patients who are busy at work and do not have time for treatment, and they can even use long holidays such as the National Day to receive treatment and have a recovery holiday. Arthroscopy has a wide range of applications. Arthroscopic surgery can be performed on large joints such as hip, knee, ankle, shoulder, elbow, wrist, and even finger joints. It can be used for both diagnosis and treatment; it can treat both chronic diseases such as arthritis and acute traumas such as fractures; at present, the most applied arthroscopic treatment is for the knee and shoulder joints, and osteoarthritis, joint free bodies, meniscal injuries, and frozen shoulder are the most common indications.
