Abstract
Apparatus for autogenous or allograft transplantation of articular cartilage with bone from one site, such as in the knee, to another to treat chondral defects. Graft harvesters and recipient site harvesters create identically-sized donor graft osteochondral cores and recipient sockets. Collared pins disposed within the harvesters facilitate removal of the harvested cores. Windows formed in the side of the harvester tubes allow visualization of the graft, such as when being inserted into the recipient socket. A removable three-piece driver/extractor is provided to allow for impact-driving and depth control of the harvesters at the selected sites.
