FIGURE 6.
Posterior view on the knee. (A) A centerline was generated connecting the femoral ACL origin and the tibial ACL insertion. (B) A tube with varying radius was fitted around the centerline to model the ACL. (C) A second centerline was forced to wrap around the ACL when connecting the femoral PCL origin and the tibial PCL insertion. (D) A tube fitted around the centerline with a varying radius formed the PCL.
