Orthopaedic Implant Coatings: Recent Approaches and Clinical Translation


Despite improved surgical techniques and prophylactic procedures, orthopaedic implant-associated infections remain high with complications that can lead to devastating outcomes for the patient. Implant coatings and associated surface modifi cation techniques represent a promising means to prevent infections. Various approaches have emerged to address the challenges associated with implant infections, such as antibacterial resistance, biofi lm prevention, and appropriate effi cacy kinetics. Methods including antibiotic and antimicrobial peptide surface tethering, use of osteo-conductive and -inductive materials, and altering hydrophobicity and hydrophilicity of the implant surface, have all demonstrated effi cacy toward diminished infection risk. Though many of these techniques have shown great potential in in vitro and in vivo studies, clinical translation remains limited with very few commercially available implant coatings globally. This review summarizes recent advancements in orthopaedic implant coatings, pre-clinical studies, and clinical translation, as well as potential future marketed products.
