On the application of the rodrigues displacement equation for the generation of finite helical axes for tibial motion

抄録

This work presents an alternate method for producing the finite helical axes for tibial motion. The method includes two procedures. In the first procedure, coordinates of the tibia in each specified position throughout full knee flexion to extension are measured in spatial Cartesian form. In the second procedure, the Rodrigues displacement equation is used to calculate finite helical axis parameters from the tibial displacements.
