Rapid analysis of implant positioning effects in cementless total hip replacements
Implant positioning plays an important role in the success of cementless THRs in the early postoperative stage. Variability in positioning might be inevitable even with better pre-operative planning softwares or computer navigation. Combining multiple CAD operations and Finite Element (FE) simulations can help to capture variability effects. In the present study, FE meshes of the implanted femur were automatically generated for a range of pre-defined femur-implant configurations. Predicted micromovements at the femur-implant interface were then used to construct surrogate models to (a) compute the sensitivities of three biomechanical metrics to implant orientations and (b) identify the best and worst implant positions

Abstract
Implant positioning plays an important role in the success of cementless THRs in the early postoperative stage. Variability in positioning might be inevitable even with better pre-operative planning softwares or computer navigation. Combining multiple CAD operations and Finite Element (FE) simulations can help to capture variability effects. In the present study, FE meshes of the implanted femur were automatically generated for a range of pre-defined femur-implant configurations. Predicted micromovements at the femur-implant interface were then used to construct surrogate models to (a) compute the sensitivities of three biomechanical metrics to implant orientations and (b) identify the best and worst implant positions
