Two- and three-dimensional motion analysis methods are commonly used for the measurement of dynamiclower limb alignment. However, there has been very few comparative studies between these two methods. The purposeof the present study was to investigate the correlation of the biomechanical data between two- and three-dimensionalmotion analysis methods for the evaluation of dynamic knee alignment. Seven female and 7 male college basketballplayers were recruited to perform a drop jump test. The Knee/Hip ratio for evaluation of valgus alignment of the kneein the coronal plane was measured by a two-dimensional motion analysis system with a digital video camera. The jointkinematics and kinetics of the knee were evaluated by a three-dimensional motion analysis system. From toe touchto maximum knee flexion, the knee/hip ratio decreased significantly both in males and females. However, the kneevalgus angle and the peak knee valgus moment were not correlated with change in the knee/hip ratio. Both males andfemales showed a similar change in the knee/hip ratio in the two-dimensional motion analysis during the drop jump, butsignifi cant diff erences in joint kinematic and kinetic patterns were seen in the three-dimensional motion analysis. Thesediff erences should be taken into account when using the two diff erent motion analysis systems.
