摘要
Abstract
BACKGROUND: Although many biological reconstruction can repair defects and rebuild articular surfaces, the function is inferiorto normal cartilage. Transplantation of biodegradable polymer-coated cartilage cells may obtain real hyaline cartilage.OBJECTIVE: To observe effects of collagen-embedded chondrocytes by point implantation method on repairing articularcartilage defects.METHODS: Articular cartilage defects were made in the knee of New Zealand rabbits. The rabbits were randomly divided intothree groups, treated with collagen gel-embedded chondrocytes, chondrocytes or no treatment.RESULTS AND CONCLUSION: Histological changes were observed at 2, 4, 12 and 24 weeks postoperatively. Hyaline cartilagewas observed in rabbits following transplantation of collagen gel-embedded chondrocytes, while only fibrous tissues wereobserved in the defects in the other two groups. Moreover, mean histological and histochemical scores were greater in the rabbitstreated with collagen gel-embedded chondrocytes compared with the other groups (P < 0.01). Results show that transplantationof collagen gel-embedded chondrocytes can obtain hyaline cartilage, and can be used for repairing large-area cartilage defects.关键词
