From: Kinematic features in patients with lateral discoid meniscus injury during walking
The portable optical tracking system and process of kinematics analysis. (a) The system has a working dimension of 1 m*2.5 m*1 m (length*width*height). (b) The identification of the femoral and tibial anatomic landmarks was performed using a handheld probe before the kinematic data was captured. (c) Kinematics data was collected while the subject was walking on a treadmill for 15 seconds. (d) Definition of local femoral and tibial coordinate systems.
