Periprosthetic lesions are extremely complex, including bony changes of the wrist joint, synovial lesions, ligament injuries, tendon injuries and inflammatory changes, and cartilage injuries. Traumatic injuries such as navicular fracture, lunar dislocation, and intra-articular fracture of the distal radius are difficult to achieve ideal treatment results in conventional management, and the clinical results of open surgery for synovial growth of the wrist are not very satisfactory; early diagnosis of wrist pain is difficult, and even with the most advanced imaging examinations, it is difficult to make a correct diagnosis; early diagnosis and treatment of ligament injuries are even more delayed, often resulting in later wrist arthritis. The early diagnosis and treatment of ligament injury is even more delayed, often resulting in late wrist arthritis. For synovial lesions of the wrist, including tuberculous and rheumatic synovial hyperplasia, the use of wrist arthroscopy can effectively reduce or eliminate clinical symptoms, prevent further damage to the joint, and preserve the function of the wrist joint to the greatest extent when the clinical symptoms are controlled by medication. For acute and chronic injuries to ligaments in the wrist joint, such as the navicular ligament and lunotriquetral ligament, the use of wrist arthroscopy can provide a clear diagnosis, and treatment such as ligament reconstruction or repair can be performed under wrist arthroscopy. The use of wrist arthroscopy to treat lesions such as tendon sheath cysts and joint free bodies can significantly reduce surgical trauma and achieve ideal treatment results. The diagnosis and treatment of deltoid fibrocartilage body injuries of the wrist joint have gradually gained attention in recent years. With the development of arthroscopic technology, it has been possible to do joint cleaning and repair treatment. For fractures or dislocations in the wrist joint, conventional open surgical treatment is no longer able to meet the future clinical requirements, therefore, the development of minimally invasive surgery is gradually gaining attention, and the clinical application of arthroscopic-assisted technology is the direction and trend of future development. Minimally invasive surgical treatment of periarthrosis can solve the problems that are still unsolved in clinical practice. It can also improve the clinical treatment effect and reduce the complications of surgery. Domestic attention to the diagnosis and treatment of wrist joint lesions is still insufficient, and only a few hospitals are currently carrying out clinical work on wrist arthroscopy. Indications for wrist arthroscopy: 1. early diagnosis and treatment of synovial lesions of the wrist 2. arthroplasty for wrist arthritis 3.Diagnosis and repair of ligament injury in the wrist joint 4.Arthroscopic repositioning and internal fixation treatment of intracarpal fracture. 5.Diagnosis of wrist joint pain. 6.Arthroscopic assisted reduction of periarticular fractures and arthroscopic evaluation of the reduction. 7. Application of closed reduction techniques for periarticular fractures of the wrist. 8.Cleaning and repair of the triangular fibrocartilage body of the wrist joint. 9.Early diagnosis and treatment of midcarpal joint lesions. 10.Arthroscopic cleaning of lunar osteonecrosis in the wrist joint. 11.Arthroscopic treatment of carpal tunnel syndrome. 12.Arthroscopic assisted minimally invasive treatment of wrist joint fusion. 13.Arthroscopic surgery for dorsal wrist tendon sheath cyst. 14.Subscopic removal of wrist joint free body.
