Summary:This experimental study reports the results of implantation of cartilaginous and periosteal tissues into growth plate defects in the tibiae of sheep. When no material was used, the defect rapidly filled with marrow-like tissue. When cartilage from the margin of the secondary centre of ossification was implanted, endochondral ossification continued and no shortening or deformity resulted. Implantation of periosteum with or without reconstructed peripheral tissues resulted in the formation of a bony bridge which led to a 32% inhibition of longitudinal growth and a 12 degrees varus deformity in the absence of peripheral connective tissues. After reconstruction with these tissues, the inhibition of longitudinal growth was 47% with a 28 degrees varus deformity. The chondroprogenitor cells in the implanted tissues cannot change phenotypic expression. Periosteum has a strong potential for bone formation after it has been implanted.
