Autograft Cartilage Transfer Augmented With Bone Marrow Concentrate and Allograft Cartilage Extracellular Matrix

Abstract

The use of biologics in sports medicine is increasing rapidly. An osteochondral defect in a young active patient remains a difficult issue to treat. Autograft cartilage has tremendous advantages for the treatment of full-thickness defects, but harvesting and preparation have been difficult in the past. Disadvantages have included donor-site morbidity and the need for further surgery. With the recent development of the GraftNet device (Arthrex, Naples, FL), harvesting and delivery of autograft have become easier and can be performed arthroscopically in a single surgical procedure. Bone marrow concentrate has recently increased in popularity owing to the presence of mesenchymal stem cells. These stem cells combined with autograft cartilage and BioCartilage (Arthrex) could lead to better incorporation and healing. In this article, we show how this unique biological composite is obtained and then added in the cartilage defect during a single-stage arthroscopic procedure.
