Abstract. The purpose of this study was to compare the chondrogenic potential of free perichondrial with free periosteal grafts in the resurfacing of full-thickness defects of patellar articular cartilage in rabbits. We used adolescent New Zealand rabbits weighing between 2.4 and 3.6 kg. A 6-mm wide and 3-mm thick defect was created on the patellar articular surface. A total of 30 rabbits were randomly divided into a control group and two test groups. One test group received free perichondrial grafts (PC); the other received free periosteal grafts (PO). All the animals were killed 8 weeks after surgery. All the histological samples were scored from 0 to 17 according to a standard scoring system. Differences in the quality of the regenerated tissue were only found between the control and the test groups. There were no statistically significant histological differences between the grafted defects of the PC and the PO groups that there are not on any of the variables. The results of this study support that there are not significant differences in the quality of the repair tissue when using these two types of biological grafts.
