Osteochondral allograft transplantation from a living donor

Abstract

Treatment of extended and massive osteochondral defects is a real challenge for an orthopaedic practice. Osteochondral allograft transplantation is a possible solution for such lesions. Transplantation of osteochondral allografts has undergone extensive experimental and limited clinical study during recent decades. Graft availability, sizing, technical issues, and viral transmission represent the most problematic points. Because interest in this technique is gaining, more and more countries face the problem of a lack of tissue banks where fresh osteochondral allografts are available. We investigated the advantages of the so-called living donor transplantation of the grafts under programmed surgical conditions. We demonstrate a technique that allows the transplantation of osteochondral allografts without the need for a tissue bank. The radiologic and histologic results regarding the quality of the transplanted cartilage are presented.
