    Abstract:
    The surface of diarthrodial joints is covered by hyaline cartilage whose regeneration capacity is extremely limited. Conventional surgical techniques enable repair of full-thickness articular cartilage defects only by fibrous cartilage having poor mechanical properties. Recently, new techniques have been developed to provide hyaline or hyaline-like repair tissue in the treatment of full-thickness cartilage defects. Autologous osteochondral transplantation involves press-fit implantation of both bone and cartilage obtained from healthy articular surface. The principal indication for this technique is unifocal full-thickness chondral or osteochondral defects measuring 1 to 4 square centimeters. This surgical procedure can be performed openly or arthroscopically. The graft should be placed vertically and evenly to the joint surface. Although short-term and mid-term results are satisfactory, several problems have been reported including donor site morbidity, damage to cartilage, and incongruity and incorporation of the graft. Autologous osteochondral transplantation provides viable osteochondral units at a single stage and eliminates the need for culturing chondrocytes which is quite expensive. Currently, no surgical technique or medical treatment provide complete healing of articular cartilage defects. Autologous osteochondral transplantation is an important stage worthy of improvement in this respect.
