Abstract

Hydrogels have been considered as potential candidates for cartilage replacement due to their high-water content, extreme network hydration, excellent biocompatibility and tunable mechanical properties. Currently, the development of high-performance cartilage-inspired hydrogel lubrication materials has become a hot topic in the field of biomedical materials. This review focusses on the recent development of cartilage-inspired high-strength hydrogels from the viewpoints of bionic surface/interface and biotribology. Specifically, the composition structure and extraordinary lubrication mechanism of the natural articular cartilage are overviewed first. Subsequently, some of the novel biomimetic design strategies for preparing high strength cartilage hydrogels with various network structures are summarised in detail, while systematic evaluation of lubrication properties and mechanisms are discussed. Furthermore, new surface modification means for improving the lubrication feature of high strength cartilage hydrogel materials are presented. In addition, in order to demonstrate the application potential of cartilage hydrogels in clinical, several bonding methods to decorate hydrogels onto surfaces of natural bone tissues or artificial joint materials are introduced. Finally, current challenges and future research directions are discussed for cartilage-inspired hydrogel lubrication materials.

仿生软骨水凝胶润滑材料的研究进展
水凝胶由于其高含水量、极端网络水化、优异的生物相容性和可调节的机械性能而被认为是软骨替代的潜在候选材料。目前,高性能软骨型水凝胶润滑材料的开发已成为生物医学材料领域的研究热点。本文从仿生表面/界面和生物摩擦学的角度综述了近年来软骨型高强度水凝胶的研究进展。具体来说,首先概述了天然关节软骨的组成结构和特殊的润滑机制。随后,详细总结了制备具有各种网状结构的高强度软骨水凝胶的一些新型仿生设计策略,并对其润滑性能和机理进行了系统评价。提出了提高高强度软骨水凝胶材料润滑性能的表面改性新方法。此外,为了展示软骨水凝胶在临床中的应用潜力,介绍了几种将水凝胶装饰在天然骨组织或人工关节材料表面的粘接方法。最后,对软骨型水凝胶润滑材料面临的挑战和未来的研究方向进行了讨论。
