What is arthroscopic surgery? Arthroscopic surgery is a major advancement in minimally invasive surgery in the field of orthopedics and is the development direction of joint surgery. In recent years, with the development of medical knowledge and the continuous improvement of medical equipment, arthroscopic surgery has been accepted by more and more doctors and patients with its significant advantages. Some hospitals have specialized arthroscopists, and some hospitals have set up specialized arthroscopic treatment centers, such as the China Railway Construction Wei Liande International Arthroscopic Treatment Center, and the treatment effect has been close to the international level, bringing gospel to the majority of joint disease patients. Arthroscopy is the crystallization of modern technology, which consists of lenses, light sources, monitors, under-scope surgical instruments, planing systems, etc. New technologies such as radiofrequency vaporization and laser have also been widely used in arthroscopic surgery in recent years. When doing arthroscopic surgery, only water is needed to dilate the joint, the surgeon 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 inside the joint can be displayed very clearly, and the effect of the lesion on the joint can also be dynamically observed, and the surgeon can make a clear At the same time, surgical instruments can be inserted through a separate incision to treat the intra-articular lesions, such as removing swollen synovial membranes, removing bone fragments that affect joint movement, suturing torn menisci, reconstructing 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, much less painful, less complications, quicker recovery, earlier release from bed, significantly shorter hospital stay, and correspondingly less hospitalization costs. Moreover, the small incision also eliminates the fear of postoperative scarring for many patients, especially female patients, 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 can even take advantage of 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 trauma such as fractures; it can also be used for extra-articular procedures, such as taking internal fixation. 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. As the standard of living of the general public has improved, sports have become part of daily life, and sports injuries are becoming more and more frequent, arthroscopy is also promising in this regard. 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. However, diseases such as knee osteoarthritis and frozen shoulder have caused great pain to many elderly people and added a great burden to their families. Arthroscopic surgery is an effective method for treating these diseases, which can significantly reduce patients’ pain and improve joint function. Therefore, arthroscopic technology will definitely have a broad development prospect for the benefit of the general public. The concept of “minimally invasive” in the history of medicine refers to the change of the traditional “open knife” surgical method and the use of modern high-tech endoscopic (such as arthroscopy) intervention and implementation of surgery to reduce the patient’s treatment pain and reduce the medical complications of traditional surgery. For patients with early-stage osteoarthrosis, arthroscopic surgery can examine, diagnose and treat various diseases in the human bone and joint. Minimally invasive arthroscopic surgery, which has emerged in the last two decades, is the latest medical technology in the world for the treatment of early-stage osteoarthrosis. Arthroscopic surgery for knee joint diseases and other joints and its superiority? The so-called arthroscopy is a procedure in which a special camera lens is placed in the joint space and the lesion in the joint is observed through a TV screen. If a lesion is found, surgical instruments are placed in the hole to remove the lesion or perform joint cleaning, whereas conventional knee surgery in the past required an incision of about 10 cm. The following knee surgeries can be performed arthroscopically: (1) meniscectomy, partial or total removal of the knee meniscus; (2) release of stiff knee meatus; (3) removal of free bodies from the knee joint; (4) knee debridement for osteoarthritis; (5) reconstruction of the anterior cruciate ligament of the knee joint; (6) synovial embedment of the knee joint, which is difficult to diagnose by clinical examination or various ancillary tests, including CT or MRI. However, arthroscopy can make a definite diagnosis and perform resection under the scope. In addition, arthroscopy can also be performed for unexplained swelling and pain in the shoulder, knee, ankle, elbow and hip joints to determine the cause of the disease and remove the lesion at the same time. osteoarthritis cleanup. If joint swelling (i.e., intra-articular bleeding) occurs immediately after trauma, this indicates structural damage within the joint, and arthroscopic exploration can be performed for early detection and timely management. Arthroscopy has those advantages: Arthroscopy is a minimally invasive procedure. Arthroscopic surgery has obvious advantages: (1) Accurate diagnosis, with an accuracy rate of 98%, which is cost-effective for the patient. (2) Small surgical trauma, only 6 mm; short hospital stay, 5-6 days to remove stitches. (3) Quick recovery, complete recovery in 1-2 weeks after surgery, and the common complications after surgery are significantly reduced. With the progress of science, the development of society, and the improvement of medical technology, the majority of patients with joint diseases have a practical solution to their ailments —- arthroscopic surgery. It can be said that in the field of joint surgery, only a few surgeries such as joint replacement and tumor resection cannot be performed by arthroscopy, and most of the joint injuries can be treated by arthroscopic surgery. Arthroscopic surgery has been used in China for two decades as a minimally invasive technique in joint surgery, but it is only in recent years that it has really developed rapidly. Arthroscopic surgery research is constantly expanding into new fields of application, introducing new techniques, new ideas and new theories. Its advanced, innovative and scientific nature has shown great value and importance in clinical applications. What other joint diseases can arthroscopy treat? Many patients have received excellent results after arthroscopic treatment, and their joints have regained their former vitality and function. So what exactly can arthroscopy do? Firstly, it is the diagnostic examination of all joint diseases, secondly, it is the removal of intra-articular free bodies, the treatment of synovial lesions of various diseases, the cleaning of osteoarthritis, the debridement and irrigation of septic arthritis, the removal of foci of joint tuberculosis; the removal, suturing and disc cartilage shaping of meniscus or disc cartilage injuries in the knee joint, the repair or reconstruction of cruciate ligament injuries, the patellofemoral dislocation or subluxation caused by Patellofemoral joint lesions: release of the lateral support band and tightening and suturing of the medial support band; frozen shoulder, rotator cuff injury, recurrent shoulder dislocation, shoulder instability. In the shoulder joint, we can perform release of carpal tunnel syndrome, osteotomy for anterior ankle impingement, painful arthritis of the hip joint, early to mid-stage aseptic necrosis of the femoral head, resection of the glenoid labrum and round ligament inlay of the acetabulum, etc. In addition, arthroscopic surgery is used outside the joint, such as: hip contracture, cysts in the national fossa, internal fixation such as taking plates, bone grafting, fusion, etc. In conclusion, arthroscopy is widely used, and its surgical features are less trauma, less pain, faster recovery, less complications, and no great medical risks for patients. The development of minimally invasive techniques has enabled many patients to quickly get rid of the disease and return to work again. In a nutshell: small incisions solve big problems. What are the possible complications of arthroscopic surgery? In general, there are few serious complications, but care should be taken not to infect the wound. Swelling or accumulation of blood or fluid in the joint cavity within 2-3 weeks after surgery is a normal reaction and can be absorbed with puncture drainage or physical therapy to help. Clinical symptoms will gradually disappear after 2-3 months depending on the condition of the intra-articular lesion, and are not immediately resolved after surgery.
