This retrospective observational case-control study aims to evaluate imaging features and associated soft-tissue injury patterns in patients with Schatzker type IV tibial plateau fractures. Adult patients treated surgically at a single tertiary trauma center between January 2019 and December 2025 are included if complete preoperative radiographs, computed tomography (CT), and magnetic resonance imaging (MRI) are available. Participants are categorized into fracture-dislocation and non-dislocation groups based on preoperative imaging findings. The study evaluates morphological characteristics of the lateral and posterolateral tibial plateau on CT as well as associated soft-tissue injuries on MRI, including ligamentous, meniscal, and bone contusion patterns. The objective of the study is to characterize imaging features associated with fracture-dislocation and to explore relationships between osseous injury morphology and soft-tissue injury patterns in Schatzker type IV tibial plateau fractures.
