| 1 | Clinical translation and challenges of biodegradable magnesium-based interference screws in ACL reconstruction显示文摘As one of the most promising fixators developed for anterior cruciate ligament(ACL)reconstruction,biodegradable magnesium(Mg)-based interference screws have gained increasing attention attributed to their appropriate modulus and favorable biological properties during degradation after surgical insertion.However,its fast degradation and insufficient mechanical strength have also been recognized as one of the major causes to limit their further application clinically.This review focused on the following four parts.Firstly,the advantages of Mg or its alloys over their counterparts as orthopaedic implants in the fixation of tendon grafts in ACL reconstruction were discussed.Subsequently,the underlying mechanisms behind the contributions of Mg ions to the tendon-bone healing were introduced.Thirdly,the technical challenges of Mg-based interference screws towards clinical trials were discussed,which was followed by the introduction of currently used modification methods for gaining improved corrosion resistance and mechanical properties.Finally,novel strategies including development of Mg/Titanium(Ti)hybrid fixators and Mg-based screws with innovative structure for achieving clinically customized therapies were proposed.Collectively,the advancements in the basic and translational research on the Mg-based interference screws may lay the foundation for exploring a new era in the treatment of the tendon-bone insertion(TBI)and related disorders. | Ying Luo Chao Zhang Jue Wang Fangfei Liu Kelvin Wingho Chau Ling Qin Jiali Wang | 2021 | Bioactive Materials2021，6，10： | 4 |
