Anterior cruciate ligament (ACL) injuries are one of the most common and significant sports injuries, and they can seriously impede knee joint function if left untreated. However, the widely used artificial ligament has minimal antibacterial activity, which limits its therapeutic applicability. To increase the antibacterial efficacy of artificial ligaments, we created and synthesized metallic glass thin films (MGTFs) based on magnesium for use in composite artificial ligament materials. Then, the materials' structure, resistance to corrosion, antibacterial qualities, and biocompatibility are thoroughly examined both in vitro and in vivo. According to the studies, the corrosion resistance can be considerably enhanced by Mg-based MG in contrast to pure magnesium. Mg-based MGTFs exhibit considerable, observable bactericidal effects and limit biofilm formation, as demonstrated by examination of in vitro antibacterial results. Evaluation s from in vivo biology suggest that no gas cavities developed as a result of hydrogen release in any of MG groups, which proves beneficial for reducing bone necrosis and inhibiting knee joint infection. In the realm of orthopedics, the research discoveries presented in our work offer a multifunctional artificial ligament material with osteogenic activity and antibacterial effect.
