Background and Objectives: This study investigated associated meniscus and ligament injuries in tibial plateau fractures using magnetic resonance imaging (MRI) and assessed soft tissue injuries in relation to the Schatzker classification and Tscherne classification. Materials and Methods: The data of 185 patients who sustained tibial plateau fractures from January 2010 to April 2021 were retrospectively reviewed. Fractures were classified according to the Schatzker classification system. Soft-tissue injuries were assessed using the Tscherne classification. Menisci and ligaments were evaluated using preoperative MRI. Nerve injuries, compartment syndrome and wound problems were also assessed. The incidence of soft tissue injuries, as well as the relationship between the Schatzker and Tscherne classification systems, were analyzed. Results: Evidence of derangement of meniscus and ligament around the knee was found in 183 (98.9%) patients. The most common injury was a medial collateral ligament injury. The incidence of lateral collateral ligament injury, nerve injury, compartment syndrome and wound problem was higher in high-energy tibial plateau fractures. A tendency was observed between the Schatzker and the Tscherne classifications (p value < 0.001). Higher Tscherne grade was also associated with the incidence of posterior cruciate ligament injury, nerve injury and compartment syndrome. Conclusions: In tibial plateau fractures, soft tissue injuries were highly prevalent. High-energy fractures tended to exhibit higher Tscherne classification grades and showed an increased incidence of meniscus and ligament injuries. The Tscherne classification appears to be a helpful system for predicting soft tissue injuries in tibial plateau fractures. And preoperative MRI can be a helpful tool.
