解剖因素在前交叉韧带损伤中所起的作用仍不清楚。在这项研究中，使用客观的方法来描述前交叉韧带的体积、胫骨倾斜度和切迹几何形状，这些来自前交叉韧带损伤和匹配的对照组受试者。本研究检验了四个假设：1)损伤组的胫骨内侧平台坡度比非损伤组大，2)损伤组的胫骨平台外侧坡度比非损伤组大，3)损伤组股骨髁间切迹尺寸比非损伤组小，4)前交叉韧带体积、胫骨平台坡度和髁间切迹尺寸都是相互独立的。54名受试者被分成两组，那些遭受非接触性前交叉韧带损伤的人和那些仍然有两个健康的前交叉韧带的人，在性别、年龄、身高和体重上与受伤的受试者相匹配。受试者健侧膝关节的胫骨平台后倾角明显增大(1.8°vs.acl.3°)，这可能是−损伤的原因之一。损伤组的髁间切迹尺寸较小，有可能使前交叉韧带处于撞击的危险中，而且髁间切迹体积与前交叉韧带体积呈正相关(r=0.58)。判别分析显示，入口切迹宽度是预测前交叉韧带损伤的最佳单项指标。
The role played by anatomic factors in ACL injury remains elusive. In this study, objective methods were used to characterize ACL volume, tibial slopes, and notch geometry from ACL-injured and matched control subjects. The study tested four hypotheses: 1) the medial tibial plateau slope is steeper posteriorly in the injured group compared to the non-injured group, 2) the lateral tibial plateau slope is steeper posteriorly in the injured group compared to the non-injured group, 3) the femoral intercondylar notch dimensions are smaller in the injured group compared to the non-injured group and 4) the ACL volume, tibial plateau slopes and intercondylar notch dimensions are all independent of each other. Fifty-four subjects were divided into two groups, those who had suffered a non-contact ACL injury and those who still had two healthy ACLs, matched to the injured subjects by gender, age, height and weight. The lateral tibial plateaus in the uninjured contralateral knees of the injured subjects had a significantly steeper posterior slope (1.8° vs. −0.3°), a factor that potentially contributed to the ACL injury in the opposite knee. The intercondylar notch dimensions were found to be smaller in the injured subjects, potentially putting the ACL at risk of impingement, and intercondylar notch volume was correlated to ACL volume (r=0.58). Discriminant analysis showed that the notch width at the inlet was the best single predictor of ACL injury.
