摘　　要：背景:前交叉韧带胫骨止点撕脱骨折是一种特殊类型的关节内骨折,多见于运动性损伤,目前关于该病的解剖学研究相对较少,而大量研究集中于前交叉韧带的损伤,普遍认为胫骨平台后倾角增大、内侧胫骨平台深度减小及股骨髁间窝缺口宽度指数减小是前交叉韧带损伤的危险因素,对于前交叉韧带胫骨止点撕脱骨折是否也与其相关尚不清楚。目的:探讨前交叉韧带胫骨止点撕脱骨折与胫骨平台后倾角、内侧胫骨平台深度、股骨髁间窝缺口宽度指数及胫骨平台冠状斜坡角度的相关性。方法:回顾性分析2019年1月至2022年12月因膝前疼痛就诊于徐州医科大学附属医院骨科的患者101例,其中接受关节镜治疗的51例前交叉韧带胫骨止点撕脱骨折患者为观察组,同期50例有膝前痛症状但查体及影像学检查确定无膝关节损伤的患者为对照组。通过术前MRI图像测定两组患者胫骨平台后倾角、内侧胫骨平台深度、股骨髁间窝缺口宽度指数等解剖学参数,统计分析导致前交叉韧带胫骨止点撕脱骨折的解剖学危险因素。结果与结论:①两组患者的外侧胫骨平台后倾角、外侧/内侧胫骨平台后倾角比值以及股骨髁间窝缺口宽度指数、胫骨平台冠状斜坡角度比较差异无显著性意义(P>0.05);观察组患者的内侧胫骨平台后倾角大于对照组(P<0.05),内侧胫骨平台深度小于对照组(P<0.05);②多因素Logistic回归分析显示,内侧胫骨平台后倾角及内侧胫骨平台深度是前交叉韧带胫骨止点撕脱骨折的独立危险因素(P<0.05);③受试者工作特征曲线显示内侧胫骨平台后倾角及内侧胫骨平台深度对前交叉韧带胫骨止点撕脱骨折有一定的预测价值;④提示内侧胫骨平台后倾角增大、较浅的内侧胫骨平台深度是前交叉韧带胫骨止点撕脱骨折的解剖学危险因素。BACKGROUND:Anterior cruciate ligament avulsion fracture at tibial insertion is a special type of intra-articular fracture,which is mostly seen in sports injuries.At present,there are relatively few anatomical studies on this disease,but a large number of studies focus on the injury of the anterior cruciate ligament.It is generally believed that the increase in the posterior slope of the tibial plateau,the decrease of the depth of the medial tibial plateau,and the decrease in the width index of the femoral intercondylar notch are the risk factors for the injury of the anterior cruciate ligament.It is unclear whether avulsion fractures of the anterior cruciate ligament at the tibial insertion point are also related to it.OBJECTIVE:To investigate the correlation between the avulsion fracture of the anterior cruciate ligament at the tibial insertion and the posterior tibial slope,the medial tibial depth,the notch width index of the femoral intercondylar fossa,and the coronal slope angle of the tibial plateau.METHODS:A retrospective analysis was made on 101 patients who were admitted to the Department of Orthopedics of Affiliated Hospital of Xuzhou Medical University due to anterior knee pain from January 2019 to December 2022.Totally 51 patients with tibial insertion avulsion fracture of anterior cruciate ligament who received arthroscopy treatment were taken as the observation group,and 50 patients with anterior knee pain but no knee joint injury confirmed by physical examination and imaging examination were taken as the control group in the same period.The posterior tibial slope,anatomical parameters such as the medial tibial depth,and the notch width index of the femoral intercondylar fossa,were statistically analyzed for the anatomical risk factors leading to the tibial insertion avulsion fracture of the anterior cruciate ligament.RESULTS AND CONCLUSION:(1)There was no significant difference between the two groups in the comparison of the lateral posterior tibial slope,the posterior slope ratio of the lateral/med
