Orthopaedic biomaterials is a multidisciplinary research field focused on the design, development, and application of materials specifically engineered for orthopaedic uses. It investigates materials intended to augment, repair, or replace natural musculoskeletal tissues, or assist in their healing, prioritizing the critical interplay between their mechanical properties and biological performance, including biocompatibility, tissue integration, and regenerative capacity. This field is pivotal to the advancement of modern orthopaedic surgery and actively incorporates emerging trends like personalized implants, smart materials, nanotechnology, and regenerative medicine to improve patient care and clinical outcomes.
