Arthroscopy is a commonly used minimally invasive examination and treatment method in clinical practice,but it has the problem of easily obstructing the view by the joint tissue.Its application often requires cooperation with other imaging examination methods.With the continuous development of medical equipment and computer image processing technology,computer-assisted surgical methods have become relatively mature in departments such as general surgery and orthopedics,providing accurate navigation during surgery.Therefore,the application of computer-assisted surgical methods in arthroscopic surgery is gradually attracting attention.This article analyzes the principles and techniques of computer-assisted orthopedic surgery,analyzes the progress and technical feasibility of computer-aided arthroscopic surgery in diagnosis and treatment from aspects such as preoperative imaging,intraoperative navigation,and robotic arm operation,explores its potential clinical application value,discusses its existing problems,and hopes to further improve the diagnosis and treatment of arthroscopic surgery in China.
