The Allograft OATS instrumentation facilitates harvesting of large diameter osteochondral/hyaline cartilage cylinders from an allograft bone. The core is made by placing the allograft condyle into the workstation and harvesting with the donor harvester. A recipient socket is created 0.5 mm undersized with the appropriate sized recipient harvester. The exact depth of the allograft to match the socket is obtained with the depth measurement guide and the allograft is trimmed to the same depth and obliquity. Dilation of the socket results in a line-to-line fit once the donor allograft is inserted into the recipient socket. Final seating of the allograft is achieved with an oversized tamp, resulting in a perfectly flush, press-fit graft that does not require fixation implants.
