本研究的目的是利用三维运动捕捉技术来评估正常步态下胫股关节的螺丝回家运动。这项研究包括15名年轻男性和15名年轻女性(总共60个膝关节)，他们没有肌肉骨骼疾病或特定步态问题的病史。除了海伦-海斯标记集之外，还有两个标记附加到了受试者身上。在此基础上，利用Skype Builder软件建立了股骨冠状平面(PF)和胫骨冠状平面(PT)两个虚拟平面。这项研究测量了正常步态下膝关节在这两个虚拟平面(Pf和Pt)的矢状面、冠状面和横面的三维运动。在运动学和动力学方面，男性和女性都表现出正常的成人步态模式，时间步态参数的平均差异没有统计学意义(p>；0.05)。在横向平面上，在摆动前阶段和摆动后期，螺杆向内移动，角度约为17°。然而，胫骨相对于股骨向外旋转，而不是相对于股骨向内旋转，而膝关节在负荷响应过程中开始弯曲(矛盾的螺丝钉-家运动)，角度为6°。自相矛盾的螺丝回家运动可能是在剩下的站立阶段为膝关节提供稳定性的重要机制。获得膝关节在步态过程中的运动学数据，有助于病理性膝关节的诊断和治疗。
The purpose of this study was to evaluate the screw-home movement at the tibiofemoral joint during normal gait by utilizing the 3-dimensional motion capture technique. Fifteen young males and fifteen young females (total 60 knee joints) who had no history of musculoskeletal disease or a particular gait problem were included in this study. Two more markers were attached to the subject in addition to the Helen-Hayes marker set. Thus, two virtual planes, femoral coronal plane (Pf) and tibial coronal plane (Pt), were created by Skeletal Builder software. This study measured the 3-dimensional knee joint movement in the sagittal, coronal, and transverse planes of these two virtual planes (Pf and Pt) during normal gait. With respect to kinematics and kinetics, both males and females showed normal adult gait patterns, and the mean difference in the temporal gait parameters was not statistically significant (p > 0.05). In the transverse plane, the screw-home movement occurred as expected during the pre-swing phase and the late-swing phase at an angle of about 17°. However, the tibia rotated externally with respect to the femur, rather than internally, while the knee joint started to flex during the loading response (paradoxical screw-home movement), and the angle was 6°. Paradoxical screw-home movement may be an important mechanism that provides stability to the knee joint during the remaining stance phase. Obtaining the kinematic values of the knee joint during gait can be useful in diagnosing and treating the pathological knee joints.
