AB  - BACKGROUND: Posterolateral tibial plateau fractures (PTPF) remain a challenge for 
      orthopedics surgeons because the special anatomical structures of the 
      posterolateral corner of knee joint including the fibular head, the lateral 
      collateral ligament, and the peroneal nerve, which impedes the exposure of the 
      fracture fragments and need irregular implants to get a stable fixation. The 
      purpose of present study was to introduce a new articular fracture fragments 
      restoration technique for three patterns of PTPF and investigate the relationship 
      between associated soft injuries and fracture patterns. METHODS: From May 2016 to 
      April 2018, 31 patients with PTPF who had undertaken arthroscopically assisted 
      reduction and fixation (AARF) were enrolled in present study. Demographic data, 
      pre-operation, and post-operation X plan films, three-dimensional computed 
      tomography (CT) scans and magnetic resonance imaging (MRI) were reviewed. Present 
      samples were divided into three patterns with lateral inclination (LI), posterior 
      inclination (PI), and parallel compression (PC) according to the orientation of 
      the articular fragment inclination. Rasmussen anatomical score was used to assess 
      the radiological results. Rasmussen functional score, Hospital for Special 
      Surgery knee-rating Score (HSS), and range of motion (ROM) of the knee joint at 
      the final follow-up were measured to evaluate the clinical outcomes. RESULTS: In 
      this series, the post-operation tibial plateau angle (TPA) was 9.7 degrees  +/- 3.5 degrees (range 
      4.0 degrees -15.8 degrees ) and the Rasmussen anatomical score was 17.7 +/- 0.7(range 16-18); 
      clinical outcomes showed that the HSS score was 92.7 +/- 21.8 (range 90-96) and the 
      Rasmussen functional score was 27.9 +/- 1.0 (range 26-30). Of all the patients, the 
      anterior cruciate ligament (ACL) injuries including the ACL tibial attachment 
      ruptures occurred in 16 patients (51.6%), meniscus lesions happened in 19 
      patients (61.3%), medial collateral ligament (MCL) injuries were founded in 13 
      patients (41.9%). The number of ACL injuries including the ACL tibial attachment 
      ruptures in the PI fracture pattern (12 cases) is significantly higher than LI (2 
      cases) and PC (2 cases) fracture pattern (p < 0.05). CONCLUSION: Profound 
      understanding the different patterns of PTPF and using our reduction technique 
      will facilitate to restore the main articular fracture fragments. The PI fracture 
      patterns have a significant high incidence of the ACL ruptures. LEVEL OF 
      EVIDENCE: Therapeutic study, Level IV.
