膝关节外翻着地是前十字韧带(ACL)损伤的危险因素。利用线性和非线性回归分析，本研究的目的是检验在跳跃着陆任务中测量的二维(2D)膝关节外翻和三维(3D)膝关节运动学之间的相关性。28名女大学生运动员参加了比赛。所有参与者都被要求进行连续跳跃测试。使用点群技术测量着陆过程中的平均最大外展角度和胫骨内旋角度。使用2D方法测量平均膝关节最大外翻角度。对2D外翻与3D膝关节外展、2D外翻与3D胫骨内旋进行线性和非线性回归分析。2D外翻与3D膝关节外展之间的R2值与零有显著差异，且在所有模型中均呈中等相关，而2D外翻与3D胫骨内旋之间的R2值与零之间无显著差异。2D方法可用于筛查特定人群的前交叉韧带损伤风险；然而，不建议使用外翻运动的额面2D分析来评估胫骨内旋转。
Landing with the knee in a valgus position is recognized as a risk factor for anterior cruciate ligament (ACL) injury. Using linear and non-linear regression analyses, the purpose of this study was to examine the correlation between two-dimensional (2D) knee valgus and three-dimensional (3D) knee kinematics measured during a jump landing task. Twenty-eight female collegiate athletes participated. All participants were required to perform a continuous jump test. The average maximum angles of abduction and internal tibial rotation during landing were measured using the Point Cluster Technique. Average peak knee valgus angle was measured using a 2D approach. Linear and non-linear regression analyses between 2D valgus and 3D knee abduction, and between 2D valgus and 3D internal tibial rotation, were performed. The R2 value between 2D valgus and 3D knee abduction was significantly different from zero and had a moderate correlation for all models, whereas the R2 value between 2D valgus and 3D internal tibial rotation was not significantly different from zero. The 2D approach could be used to screen a specific group of individuals for risk of ACL injury; however, using frontal plane 2D analysis of valgus motion to evaluate internal tibial rotation is not advised.
