| Abstract Scope |
Patients who undergo Total Hip Anthroplasty (THA) are known to require revision surgery within ten years. The variance in stiffness between the biocompatible implant material and bone materials often leads to bone remodelling which manifests in pain, aseptic loosening, bone-implant interface fracture and mechanical wear. Metamaterial design and additive manufacturing strategies have expanded the space of achievable mechanical properties. A framework is derived that leverages multiscale topology optimisation and inverse-design to derive optimal implant material layout. This work demonstrates that optimal implant configuration can be derived given patient-specific loading to minimize bone remodelling and the risk for interface fracture and aseptic loosening. |
