自体镶嵌式骨软骨移植修复膝关节软骨缺损

Repairing cartilage defects of knee joint by using osteochondral autograft

目的 探讨膝关节软骨缺损的修复方法。 方法 6例膝关节软骨缺损患者 ,关节镜下在其非负重区的软骨面上 ,用专用器械凿取圆柱状的骨软骨 ,并移植至软骨缺损部位 ,用于修复缺损。 结果 随访 2～ 2 4个月 ,患者的临床症状消失 ,关节活动度正常 ,MRI显示原软骨缺损区软骨表面平整 ,移植的骨软骨柱位置良好。 结论 自体镶嵌式骨软骨移植术创伤小、操作简单、能保持关节面的曲度 ,是较为实用的手术。

Objective To discuss the repair methods for the cartilage defects of the knee joint. Methods The cylindrical osteochondral grafts were harvested from the non-weight-bearing area of the knee joint and then transplanted to the cartilage defects in 6 patients with cartilage defects of the knee joint. Results The clinical symptoms of all the patients followed up for 2-24 months disappeared and the joint mobility recovered to normal. A follow-up MRI showed consistent cartilage coverage and the excellent position of the cylindrical osteochondral grafts. Conclusions The osteochondral autograft is a practical surgical method because it is characterized by less trauma, simple performance and good maintenance of the curvature of the articular surface.
