General note Conventional solid orthopedic implants face various mechanical and biological issues when<br/>they are implanted in the human body. The most important mechanical problem being faced<br/>due to use of these implants is stress shielding effect which is caused by mismatch of<br/>mechanical properties, Young’s modulus and yield strength, between the implant and host<br/>bone. Porous orthopedic implants designed with lattice structures can overcome this problem<br/>as their mechanical properties can be tailored to match with host bone. For this purpose, it is<br/>important to understand the effects of topological parameters of lattice structure on its<br/>mechanical properties. In this work, eighteen lattice structures have been systematically<br/>modelled keeping in view the predefined porosity range for lattice structures intended to be<br/>used in orthopedic implants. Finite element analyses (FEA) have been carried out on these<br/>lattice structures modelled with IsoTruss, Diamond and Fluorite unit cell types, 0.200mm,<br/>0.225mm and 0.250mm strut thicknesses, and 3.375mm3<br/>and 1 mm3<br/>of unit cell volumes where<br/>each lattice structure contains either value of these topological parameters. Young’s modulus<br/>and yield strength of each lattice structure under uniaxial compression loading are determined<br/>from the results of FEA. The material of lattice structures used in this work is 316L stainless<br/>steel. Sixteen lattice structures have been found within the predefined porosity range. Out of<br/>eighteen lattice structures, Young’s moduli and yield strengths of only nine lattice structures<br/>have been laid within the range of these properties for either trabecular or cortical bones. The<br/>trends of these properties to the change in topological parameters have been observed. The<br/>sensitivity of these properties to the change in topological parameters for various categories of<br/>lattice structures and the efficiency of each lattice structure to use its material content for<br/>increasing the mechanical properties have also been determined. Furthermore, all lattice<br/>structures having similar type of unit cell have been found in conformity with Ashby-Gibson<br/>model.
