Clinical Correlation Analysis Between Tibial Plateau Fracture And Knee Lateral Collateral Ligament Injury

Objective: By exploring imaging materials of patients with tibial plateau fractures,we want to reveal the relationship between tibial plateau fractures and lateral collateral ligament(LCL)injury.Methods: A total of 107 patients with tibial plateau fractures were selected from the Trauma Emergency Center of the Third Hospital of Hebei Medical University.All patients underwent plain radiographs of the knee joint,computed tomography(CT) and Magnetic resonance imaging(MRI)examinations of the knee joint.According to the imaging results,the tibial plateau fractures were classified,and the number of LCL injuries was counted.By analyzing the incidence of injuries,we explore the relationship between injuries and the classification of tibial plateau fractures.Results: A total of 107 cases of tibial plateau fractures were included in this study.According to Schatzker classification,there were 16 cases of type Ⅰ,24 cases of type Ⅱ,14 cases of type Ⅲ,21 cases of type Ⅳ,10 cases of type Ⅴ,and 22 cases of type Ⅵ.According to AO/OTA classification,there were 75 cases of 41-B type and 32 cases of 41-C type.Tibial plateau fractures were associated with LCL injury in 29 cases(27%).In Schatzker Ⅰ to Ⅵ fractures,the incidence of lateral collateral ligament injuries was 18%,21%,0%,48%,40%,32%,and the differences were statistically significant.The incidence of LCL injury in high-energy injury(Schatzker Ⅳ,Ⅴ,Ⅵ) was 40%,and the incidence of LCL injury in low-energy injury(Schatzker Ⅰ,Ⅱ,Ⅲ) was 15%.The difference is statistically significant.The incidence of LCL injury in AO/OTA fracture classifications 41-B and 41-C was 24% and 34%,respectively,and there was no significant difference.Conclusions: In the Schatzker classification,the incidence of LCL injury varies among fracture types.Schatzker Ⅳ,Ⅴ,and Ⅵ fractures have a higher incidence of LCL injuries,with the highest incidence of LCL injuries being type Ⅳ.In the AO/OTA system classification,there was no significant difference in the incidence of LCL injuries between 41-B fractures and 41-C fractures.
