Cartilage Transplant

The Allograft OATS Instrumentation set facilitates harvesting of large diameter osteochondral/hyaline cartilage cylinders from an allograft bone. The core is made by placing the allograft into the workstation and harvesting the proper size core with the donor core harvester. A recipient socket is created that is 0.5 mm undersized with the appropriately sized recipient harvester. The exact depth of the allograft to match the socket is created with the depth measurement guide, trimming the allograft 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 using gentle taps, resulting in a perfectly flush graft to the surrounding articular surface.
