摘要:

背景:如何利用组织工程学的方法促进膝关节软骨修复及缩短病程成为关节外科亟需解决的问题,而微骨折加干细胞移植疗法有可能为其开辟一条新的道路。

目的:探讨关节镜下微骨折加自体骨髓间充质干细胞移植治疗膝关节软骨损伤的可行性。
方法:2010年10月至2012年3月收治的膝关节软骨损伤患者16例,男12例,女4例;左膝11例、右膝5例;年龄16-52岁,平均38.6岁;所有病例软骨缺损均获得关节镜证实。治疗前2周抽取自体骨髓,分离骨髓间充质干细胞并行体外培养扩增,获取干细胞培养液3-5 mL(约107个细胞)。膝关节镜下清理后微骨折尖锥于软骨缺损区钻孔,造成局部微骨折,排尽关节腔内积液,行微切口置入止血纱布贴覆软骨创面,注入制备好的骨髓间充质干细胞,弹力绷带加压包扎,早期CPM机锻炼。
结果与结论:随访4-18个月,显效13例,有效2例,无效1例。Lysholm膝关节评分治疗前为42分(33-67分),治疗4周后为89分(75-99分),平均提高47分,随访均未出现症状反复和加重。结果可见关节镜下微骨折加自体骨髓间充质干细胞移植有效治疗膝关节软骨损伤,显著改善患者膝关节症状及恢复膝关节功能。

Abstract:

BACKGROUND: It has been an urgent problem of how to promote cartilage repair of the knee and shorten the total course through a tissue engineering approach. Fortunately, microfracture plus stem cell transplantation may open up a new path for this issue.

OBJECTIVE: To investigate the clinic feasibility of arthroscopic microfracture technique plus stem cell transplantation for repair of articular cartilage injury of the knee.
METHODS: From October 2010 to March 2012, a total of 16 patients with articular cartilage injury of the knee were enrolled, including 12 males and 4 females, with the average age of 38.6 years (16-52). All cases of cartilage injury were confirmed by arthroscopy. Autologous bone marrow was extracted from patients at 2 weeks before treatment to isolate, culture and amplify bone marrow mesenchymal stem cells in vitro. The cell culture solution of 3-5 mL (about 107 cells) was harvested. The articular cavity was clean by arthroscopy and microfracture technique was performed at the area of cartilage injury that was then covered with hemostatic gauze through a minimally invasive incision and the prepared bone marrow mesenchymal stem cells were injected. The knee was bandaged with the elastic bandage after aspirating the joint cavity effusion by vacuum suction. Functional exercises were performed early by CPM. 
RESULTS AND CONCLUSION: After follow-up of 4-18 months, there were 13 cases of excellent, 2 cases of valid and 1 case of ineffective. According to Lysholm knee scores, the average scores were improved from 42 points (33-67 points) to 89 points (75-99 points) at 4 weeks after treatment. The function was satisfied and all patients were followed up without recurrence or worse. Under the arthroscopy, the combination of microfracture technique and autologous bone marrow mesenchymal stem cell transplantation is proved to be effective for articular cartilage injury of the knee and it can notably improve the clinic symptoms and recover the function of the knee.
