Abstract

The aim of this study was to evaluate the clinical outcomes of patients with posteromedial tibial plateau fractures treated by open reduction and internal fixation (ORIF) through a posteromedial approach. Thirty-six patients with posteromedial tibial plateau fracture underwent ORIF through a posteromedial approach and were retrospectively analyzed. Preoperative X-ray pictures and CT images were obtained. And there were 11 cases of posteromedial tibial plateau fracture and 25 cases of posteromedial and posterolateral tibial plateau fracture. All the patients were treated surgically with posteromedial approach. The clinical outcomes were assessed according to the Rasmussen knee function grading system. The patients were followed-up for an average of 17.5 months (range, 12-32 months). All the fractures attained satisfactory reduction. No major complications were observed. According to the Rasmussen knee function grading system, the results were graded as excellent in 21 cases, good in 13 cases, fair in 2 cases. The rate of excellent and good results was 94.4%. The posteromedial approach in our opinion is the best option to treat the posteromedial tibial plateau fractures because it can provide direct visualization of the fracture site and avoid dissection of neurovascular bundle in the popliteal fossa area with minimal soft tissue injury.
