Ingrowth of osteochondral grafts under the influence of growth factors: 6-month results of an animal study.

Introduction: In the age of growth factors and gene therapy, the induction of cartilage healing remains an unsolved problem. Even in autologous grafting, one of the preferred methods of treatment for focal osteochondral lesions, chondral integration remains difficult. This study aims to define a possible positive influence of growth factor augmentation on the ingrowth of these transplants.
