[An experimental study on changes in collagen content after homologous cartilage implantation].

This experiment studied the changes in cartilage collagen content during 1-20 weeks after allografting of cartilage. The results showed that the collagen content was reduced beginning from the 3rd week, and reached the lowest point in the 4th week (P < 0.05). Then it rose continuously and attained the normal level in the 8th week (P > 0.05). The study suggests that the changes in cartilage collagen content may help us to assess the cartilage structure and the elasticity after a cartilage allotransplantation.
