purpose. To evaluate radiological and clinical outcome of minimally invasive plate osteosynthesis (MIPO) for tibial plateau fractures. Methods. 35 men and 6 women aged 19 to 75 (mean, 40; standard deviation [SD], 14) years underwent MIPO for displaced tibial plateau fractures. According to the Schatzker system, the tibial plateau fractures were classified as types I (n=3), II (n=9), III (n=11), IV (n=6), V (n=7), and VI (n=5). Six patients had open fractures; 2 of them underwent debridement before MIPO. 10 patients needed additional bone grafting. Radiological (at immediate postoperation) and clinical (at the 12-month follow-up) assessments based on the Rasmussen anatomic and functional scoring system were recorded using a proforma. Patients with acceptable and unacceptable outcomes were compared in terms of age. results. The mean Rasmussen anatomic score was 15.1 (SD, 2.2; range, 10-18); the mean Rasmussen functional score was 25.3 (SD, 3.2; range, 14-29); and
