Abstract: BACKGROUND: For posterolateral tibial plateau fracture due to the complex anatomical relationship of its location, there are often some controversial issues in choice of surgical approach and internal fixation strategy. In addition, with the development of three-dimensional (3D) printing technique in clinical work, it has had a positive impact on surgical treatment of posterolateral tibial plateau fracture. 
OBJECTIVE: To summarize and prospect the research progress of surgical treatment of posterolateral tibial plateau fracture in surgical approach, internal fixation strategy and 3D printing technique in recent years. 
METHODS: The first author used Chinese and English search terms to search the relevant literature collected in the Web of Science, PubMed and CNKI databases from May 2011 to May 2020. The keywords were “tibial plateau, posterolateral, fracture, approach, internal fixation, 3D printing” in English and Chinese. The relevant literature was screened and sorted out, and conducted a detailed review.
RESULTS AND CONCLUSION: (1) Surgical approaches of posterolateral tibial plateau fracture are mainly non-osteotomy and trans-osteotomy, of which there are many types of non-osteotomy. (2) The posterolateral approach is a direct approach, and the surrounding anatomical structure is relatively complex. Lateral and anterolateral sites can be treated with anterolateral tibial plateau fracture and the anterolateral approach does not involve important blood vessel and nerves. The posterior median approach can reveal the entire posterior tibial plateau. The posteromedial approach can be an auxiliary approach. If combined with the anterior-lateral approach, it can reveal almost the entire tibial plateau. (3) Although the osteotomy approach can increase the surgical field, it carries the complications. (4) There are many types of internal fixation materials with their own characteristics, and internal fixation method has also been improved. (5) 3D printing technique facilitates the formulation of surgical approaches and internal fixation strategies as well as research and testing of biomechanics aspects of internal fixation materials and methods. (6) In the future, it is still necessary to reach the optimal surgical access standard for posterolateral tibial plateau fracture. The new internal fixation materials not only require biomechanical testing, but also require a large number of clinical application effect analysis.
