GOBBI, Riccardo Gomes et al. Autologous chondrocyte implantation: series of 3 cases. Rev. bras. ortop. [online]. 2010, vol.45, n.4, pp.449-456. ISSN 0102-3616. http://dx.doi.org/10.1590/S0102-36162010000400019.
Hyaline cartilage in the surface of synovial joints plays an important role in lowering stress and attrition in joints such as the knee. This tissue has no blood vessels, nerves, nor lymphatic drainage, which in part explains why articular cartilage has such poor capacity for healing. Chondral lesions reaching the subchondral bone (osteochondral lesions) do not heal and may progress to osteoarthritis as time passes. In young patients, treatment of such defects is challenging, especially in lesions larger than 4 cm. One option in young adults is the autologous chondrocyte implantation, capable of filling the defect with tissue similar to hyaline cartilage without violating the subchondral bone. Theoretically, it has biological and mechanical advantages over other surgical options. In this paper, we describe the experience with this procedure in a series of 3 cases at the Institute of Orthopedics and Traumatology, University of São Paulo.
