Abstract

Due to the extremely high incidence of lesions and diseases in aging population, it is critical to put all efforts into developing a successful implant for osteochondral tissue regeneration. Many of the patients undergoing surgery present osteochondral fissure extending until the subchondral bone (corresponding to a IV grade according to the conventional radiographic classification by Berndt and Harty). Therefore, strategies for functional tissue regeneration should also aim at healing the subchondral bone and joint interface, besides hyaline cartilage. With the ambition of contributing to solving this problem, several research groups have been working intensively on the development of tailored implants that could promote that complex osteochondral regeneration. These implants may be manufactured through a wide variety of processes and use a wide variety of (bio)materials. This review aimed to examine the state of the art regarding the challenges, advantages, and drawbacks of the current strategies for osteochondral regeneration. One of the most promising approaches relies on the principles of additive manufacturing, where technologies are used that allow for the production of complex 3D structures with a high level of control, intended and predefined geometry, size, and interconnected pores, in a reproducible way. However, not all materials are suitable for these processes, and their features should be examined, targeting a successful regeneration.

摘要

由于老年人群中病变和疾病的发生率极高,全力开发一种成功的用于骨软骨组织再生的植入物至关重要。许多接受手术的患者存在延伸至软骨下骨的骨软骨裂隙(根据Berndt和Harty的传统放射学分类对应IV级)。因此,功能性组织再生策略除了透明软骨外,还应旨在修复软骨下骨和关节界面。为了致力于解决这个问题,几个研究小组一直在深入研究开发能够促进这种复杂骨软骨再生的定制植入物。这些植入物可以通过多种工艺制造,并使用多种(生物)材料。本综述旨在研究当前骨软骨再生策略在挑战、优势和缺点方面的现状。最有前途的方法之一依赖于增材制造原理,即使用能够以可重复的方式生产具有高度可控性、预定和预定义几何形状、尺寸以及相互连接孔隙的复杂三维结构的技术。然而,并非所有材料都适用于这些工艺,应针对成功再生对其特性进行研究。
