中文摘要：

目的：经微创手术制备膝关节软骨缺损动物模型，减少因手术创伤造成对实验结果的影响。方法：关节镜下对9只山羊（9膝）进行关节面钻孔术，造成软骨缺损模型，对其缺损位置进行准确定位。结果：9只山羊（9膝）均在关节镜下顺利进行了关节软骨缺损模型的建立，并进行了缺损部位的定位。结论：对比开放性手术，经关节镜制备关节缺损模型是一种对实验干预最少的微创方法，有助于减少手术本身造成的实验误差。

英文摘要：

Objective： To construct animal models of articular cartilage lesions in the knee of goats by arthroscopy to minimize the surgical injury. Methods： Subchondral drilling to create the chondral defect on articular cartilage were performed on 9 goats （9 joints） by arthroscope. Results： The chondral defect models were successefully constructed on 9 goats （9 joints） and accurately located by arthroscopy. Conclusion： Preparing animal models of chondral defects by arthroscopy result in fewer injuries and experimental errors as compared with open surgery.
