In many in vivo studies, knee kinematics have been assessed using images acquired at a series of static positions over the range of motion, however there may be differences between the kinematics estimated from sequential static poses of the joint and the kinematics of the moving joint. Ten normal subjects were examined using static and dynamic methods. Differences between dynamic and static results were seen for nine of 11 kinematic parameters Dynamic-based 3D kinematics measures provide different information from static 3D measures, and may represent kinematic results closer to those in activities of daily living.
