Biomechanical comparison of three tibial tunnel positions for PCL reconstruction: a 3D finite element analysis

Compared with the anatomic regional center point and Fanelli point reconstruction PCL, the grafts of the soft tissue reference tibial localization reconstruction PCL method were subjected to greater tensile forces, but they had significantly lower friction with the tibia and were able to reduce contact wear with the tibia. This can enhance long-term patient outcomes. Our study offers crucial biomechanical evidence for optimizing tunnel positioning in PCL reconstruction, propelling the advancement of surgical techniques.
