目的：制作不同程度关节软骨损伤的动物模型，对关节软骨损伤后软骨再生修复的组织学及超微结构进行系统研究。
Objective: We set several animal models with articular injury in various degrees and studied systemically on the histology and ultra-microscopic structure of cartilaginous regeneration after injury.
修复受损伤的膝盖是一件很复杂的事情，因为关节上的软骨是很难再生的，在一些情况下对关节进行整体更换是唯一可行的办法。
Fixing damaged knees is tricky because the form of cartilage found in the joints does not easily regenerate and in some cases total joint replacement is the only option.
目的通过引导性骨再生和组织工程软骨移植研究长骨骨缺损的修复机制。
Objective Study the mechanism of the healing of bone defect after transplantation of the tissue-engineered cartilage into the bone defects and with guided bone regeneration tubes.
关节软骨的自愈能力较差，因而外科治疗旨在修复关节软骨的缺损以促进机化的透明软骨的再生。
Articular cartilage has a poor intrinsic capacity for healing. The goal of surgical techniques to repair articular cartilage injuries is to achieve the regeneration of organized hyaline cartilage.
非软骨类组织和材料只能阻止小面积生长板缺损内骨桥形成，无再生修复能力。
Non cartilaginous tissue and material could only prevent formation of bony bridge in small defect of growth plate and lacked ability of regenerative repair.
非软骨组织材料只能阻止小面积生长板缺损内骨桥形成，无再生修复能力。
