With the development of medical technology and materials science, the structure optimization method of bioabsorbable materials for implantable medical devices becomes more and more important, and the absorbable interface screw is the most representative device in implantable medical devices. Based on the previous parametric design method for the loading and structural characteristics of the interface screw, this paper assembled the interface screw and cancellous bone with the tunnel hole and simulated the graft fixation after cruciate ligaments surgery. In this study, through the finite element method, the mechanical properties of interface screws with different structural parameters obtained by parametric design were comprehensively evaluated from the aspects of stress and strain energy density.
