https://www.selleckchem.com/ Computed tomography (CT) has become a routine preoperative examination for tibial plateau fractures (TPFs). Assessing the location of the fragment and intercondylar eminence fracture can provide clinicians with valuable information; however, the evaluation of traumatic meniscal lesion (TML) and arthroscopic management are controversial. To predict TML by three-dimensional skeletal anatomy changes in unilateral TPF and bilateral TPF on preoperative thin layer CT. Acute fracture of tibial plateau patients undergoing arthroscopic surgery between December 2017 and December 2019 were included in this retrospective study. The type, zone, and location of TMLs were diagnosed based on the operation records and/or arthroscopic videos. Measurement of three-dimensional fracture morphology included the following Frontal fragment width of plateau, sagittal fragment subsiding distance (FSD), sagittal fracture line distance, sagittal posterior tibial slope, and transversal area ratio of fragment area) on preoperative CT three-dimensional plane. The correlation of TML with skeletal values was calculated according to unicondylar TPFs and bicondylar TPFs. A total of 67 patients were enrolled in this study, among which 30 patients had TMLs, lateral/medial (23/7). FSD was a particularly positive factor to predict TML, with odds ratio of 2.31 (1.26-5.63). On sagittal view of CT, FSD degree of 8 mm and posterior tibial slope exceeding 11.74° implied enhanced risk of TML in bicondylar TPFs. On coronal view, once fragment width of plateau surpassed 3 cm, incidence of TML reached 100%. On transverse view, area ratio of fragment as enhanced risk of 5.5% and FSD > 4.3 mm for predicting TML were observed in unicondylar TPFs. TML can be predicted by different parameters on preoperative CT views according to unicondylar fractures and bicondylar TPFs. TML can be predicted by different parameters on preoperative CT views according to unicondylar fractures and bicondylar
