Resumen (ES)
An animal experimental study was designed in order to repair chondral defects of
8 mm. diameter, performed at the articular surface of the patella in adult rabitts. A total of 48 animals
were operated. The control serie consisted of 24 animals in which the defect was not repaired.
In other 24 animals, the defect was covered whit a free tibial periosteal praft. Rcsults were
evaluated macro and microscopically at 1, 2, 4 and 8 weeks after surgeon. In control cases, there
were no spontaneous repair while in case with periosteal implantation, a new trialine cartilage
originated in the implanted tissue was observed. These findings demonstrated the chondrogenic
capacity of periosteal free grafts for repair of articular surface defects.
