The purpose of this study was to verify the effect of the perichondrium graft with butyl-2-cyanoacrylate in provoked injury in the articular cartilage of rabbit`s knee. Male adult animals were used, divided in 2 groups, called Group A and Group B, with 17 animals each. The Group A animals were reoperated in 4 weeks and the Group B animals in 8 weeks. A 2 cm fragment was taken out from the 7th costal cartilage from which the perichondrium was removed. Two osteo-cartilaginous cylinders were taken out from each medialis condyles of the femurs in the same animal. The articular cartilage of the cylinder was replaced in one side by the perichondrium with a thin layer of sticking-tissue in its external face and only the articular cartilage was removed from the other side. The cylinders were replaced in the femurs. Macroscopically, in Group A, most of the injuries which received the perichondrium were found completely covered with tissue and all the lesions without perichondrium were only partilly covered. In Group B, no macroscopic significant difference in the covering of the injuries was found. Statistically, There was no microscopical significant difference between the injuries with and without perichondrium of the Group A and Group B and neither groups A and B.
