    Abstract:
    BACKGROUND: To describe the incidence of soft-tissue injuries in patients with surgically treated Schatzker type IV tibial plateau fractures. METHODS: All tibial plateau fractures in skeletally mature patients treated operatively between January 2013 and August 2018 were retrospectively reviewed using a clinical medical record system. All fractures were categorized according to the AO/OTA classifications. Twenty-seven patients with Schatzker type IV tibial plateau fractures were further classified based on the Wahlquist classification. Associated soft-tissue injuries, which consisted of cruciate ligament injuries, and meniscal and collateral ligament injuries, were diagnosed through operation notes and magnetic resonance imaging (MRI) data. The categorical variables were tested by the chi-square test or Fisher's exact test. RESULTS: The incidence of lateral meniscus tears and medial meniscus tears was 63% and 44.4% in Schatzker type IV tibial plateau fractures, respectively. Twenty-five (92.6%) patients had sustained anterior cruciate ligament (ACL) injuries, and 19 (70.4%) patients had an incomplete injury of the posterior cruciate ligament (PCL). There were 17 (63%) lateral collateral ligament (LCL) injuries, and 8 (29.6%) medial collateral ligament (MCL) injuries. Using the Wahlquist classification, these fractures were categorized as follows: type A, one patient; type B, six patients; type C, twenty patients. There was no significant difference between the type of fracture and the location of soft tissue injuries. CONCLUSIONS: This study found that operative Schatzker type IV tibial plateau fractures represented a high incidence of soft-tissue injuries, especially LCL injuries, ACL injuries, and meniscus tears. Based on our data, we believe that soft-tissue injuries in operative Schatzker type IV tibial plateau fractures deserve more attention.
