	Ante la incapacidad de reparación de las lesiones del cartílago articular, hemos diseñado un modelo experimental, consistente en la realización de una úlcera condral de 8 mm, en la superficie articular de la rótula, en 48 conejos distribuidos en 2 series. Mientras en la serie control (24 conejos) dicha úlcera se dejó a evolución espontánea, en la experimental (24 conejos) fue cubierta con plastia libre de periostio tibial para poder investigar la posibilidad de regeneración del cartílago articular. Los resultados se valoraron macroscópica y microscópicamente a intervalos de 1, 2, 4 y 8 semanas, comprobando la ausencia de regeneración espontánea y el desarrollo de un neocartílago hialino a partir de la plastia de periostio, con lo que se demuestra la capacidad condrogénica de la misma.
	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....
