半月板是人类膝关节中最常见的损伤结构。半月板缺陷已被证明会导致由于异常机械力导致的晚期骨关节炎(OA),并且该结构的替换策略已经落后于其他组织工程努力。挑战包括具有个性化尺寸参数的复杂三维结构,遇到的显著压缩、拉伸和剪切载荷,以及不良的血液供应。在这份进展报告中,我们提供了一个审查目前的临床治疗不同类型的踝关节损伤。我们讨论了细胞疗法的最新研究和这些疗法的新细胞来源。我们介绍了临床上可用的无细胞生物材料植入物和目前的进展,无细胞生物材料植入物和基于细胞的组织工程策略的半月板修复和置换,并确定当前的挑战。由于现有治疗方法的局限性,组织工程化骨关节生物复合材料植入物可能为骨关节损伤的治疗提供替代解决方案,以长期预防OA。
The meniscus is the most commonly injured structure in the human knee. Meniscus deficiency has been shown to lead to advanced osteoarthritis (OA) due to abnormal mechanical forces, and replacement strategies for this structure have lagged behind other tissue engineering endeavors. The challenges include the complex three-dimensional structure with individualized size parameters, the significant compressive, tensile and shear loads encountered, and the poor blood supply. In this progress report, we provide a review of the current clinical treatments for different types of meniscal injury. We discuss the state-of-the-art research in cellular therapies and novel cell-sources for these therapies. We present the clinically available cell-free biomaterial implants and the current progress on cell-free biomaterial implants and cell-based tissue engineering strategies for the repair and replacement of meniscus, and identify the current challenges. Tissue-engineered meniscal biocomposite implants may provide an alternative solution for the treatment of meniscal injury to prevent OA in the long run, because of the limitations of the existing therapies.
