| Abstract Scope |
Anterior cruciate ligament (ACL) reconstruction surgeries often face implant-related complications, including stress shielding, bioinert behavior, poor bone integration, and limited long-term fixation stability. Conventional metallic and polymer-based interference screws may offer limited osteointegration and mechanical stability. To address these limitations, this work presents the design, fabrication, and characterization of a 3D-printed bioceramic-based ACL interference screw. The screw was designed with interconnected porous features, including cuboidal pores in the bone-contacting region and high-aspect-ratio acicular pores in the tendon/ligament-contacting region, which may support tissue-specific integration. Yttria-stabilized zirconia served as the bioceramic for screw fabrication through high-resolution ceramic additive manufacturing, followed by debinding and high-temperature sintering. The porous design may help surrounding bone and tendon/ligament tissues grow into the screw while maintaining sufficient strength for fixation. Characterization consisted of density measurement, SEM-based microstructural evaluation, hardness and surface roughness analysis of the printed interference screws. |
