Impact of surface structure and screw fixation on primary stability in three acetabular cup systems: A biomechanical study
Implant design and surface morphology critically affect primary acetabular cup stability. Macrostructured and roughened surfaces (Allofit-S®, Revisio®-S) provide greater inherent stability, while highly porous implants (EcoFit®-Epore®) benefit evidently from screw fixation. These findings support tailored implant selection and fixation strategies based on patient-specific anatomy and surgical context to optimize outcomes in uncemented THA.
