Tibial plateau fracture is a common injury of knee joint, which generally needs surgical treatment. Compared to the open reduction surgery, arthroscopy reduction and internal fixation in the treatment of tibial plateau fracture has many advantages in direct vision of intra-articular cartilage injury, accurate reduction of fracture, optimization of diagnosis and treatment of intra-articular concomitant injury, reduction of surgical invasiveness and rapid rehabilitation, which is more in line with the concept of minimally invasive treatment. Although there is a consensus on the general principles of arthroscopic surgery, there is particularity in the selection of indications, the management of soft tissue injuries, the evaluation of therapeutic effects and surgical procedures. This article reviews the related problems of arthroscopic reduction and internal fixation in the treatment of tibial plateau fractures in order to provide reference for the treatment of tibial plateau fractures.
