TF kinematics during gait (top), stair descent (middle), and sit–stand (bottom) activities. In vivo kinematics (black) were compared to the kinematics of the cadaveric specimen using either the implant-specific boundary condition (blue) or CAMS-Knee boundary conditions (red). Shaded regions indicated one standard deviation. Horizontal bars indicate regions of significant difference between the in vivo kinematics and the two sets of cadaveric kinematics.
