摘要:

背景:自体软骨因为软骨细胞密度低,新陈代谢率低以及没有血供而导致自我修复效果不理想。

目的:就近年来组织工程技术的最新研究和外科治疗软骨损伤最新疗效方面一些最新研究及进展做一综述。
方法:由第一作者检索PubMed数据库1992年1月至2013年12月文献,在标题和摘要中以“Articular cartilage;injury;tissue engineering;repair”为检索词进行检索。根据纳入排除标准最终选取61篇文献进行分析。  

结果与结论:目前临床上常见的治疗关节软骨损伤方法有关节清理、镶嵌式成形技术、软骨膜及自体软骨细胞移植技术等,但都没研究表明某种治疗方法可以达到满意的长期疗效。其中主要的一个原因就是无法在软骨损伤处形成新的透明软骨,且修复的组织在机械性能上也无法和原有的自体软骨相比较。组织工程技术是今年来研究的热点,因其可以诱导自体软骨的形成而成为一种最有前景的治疗方法。组织工程技术利用内源性或者外源性的种子细胞,辅以诱导因子及营养因子诱导软骨的自身修复,以修复再生成有和自身软骨相似,甚至相同生物性能的透明软骨为最终的目标。如何简化治疗步骤和降低治疗费用是促进软骨再生修复进一步研究的动力。

Abstract:

BACKGROUND: Autologous cartilage has a poor self-repair effect due to low chondrocyte density, low metabolism rate and no blood supply.

OBJECTIVE: To summarize the recent study about tissue engineering techniques and surgical treatment for cartilage injury.
METHODS: A computer-based online retrieval of PubMed database was performed by the first author for articles published between January 1992 and December 2013. The key words are “articular cartilage, injury, tissue engineering, repair” in English. According to the inclusion and exclusion criteria, 61 literatures were included into the final analysis.
RESULTS and CONCLUSION: The current clinical treatment of articular cartilage injury includes joint debridement, mosaicplasty, perichondrium transplantation and autologous chondrocyte implantation. However, their long-term result is unsatisfactory. One reason for limited clinical success is that new cartilage can be formed at the site of a defect, and the repaired tissue canot compare with the autologous cartilage in mechanical property. Tissue engineering technique is still a hot topic in recent years, because it can potentially induce autologous cartilage formation. Through endogenous or ectogeneous seed cells and inducting factor and nutrient factors, tissue engineering technique can be applied to induce the self-repair of articular cartilage, thus regenerating into hyalinc cartilage with the similar even same biological property. How to simplify the treatment protocols and reduce treatment cost is the key to promote cartilage repair.
