Perichondrial grafting for total replacement of the patella. Experimental study in rabbits.
In five adult rabbits excision of the patella of one knee joint was carried out. The defects were reconstructed with free grafts taken from rib perichondrium. After survival times of 2.5 and 5 months, neocartilage was seen in all grafts on histological examination. In three of the five, the central part of the reconstructed patella showed bone formation.
