Arthrex Autograft OATS®
The Single-Use OATS® (Osteochondral Autograft Transfer System) set facilitates harvesting of 6, 8, 10, or 12 mm osteochondral cartilage cylinders from a donor site superior and lateral to the notch or above the sulcus terminalis. A recipient socket, sized to the appropriate depth, is created in the chondral defect to accept the donor graft. The bone cylinder can be visualized through the clear graft delivery tube while it is inserted with the collared pin delivery system for press-fit fixation.The completely disposable, size-specific system includes a recipient reamer, donor harvester, alignment rod, tamp, graft delivery tube, core extruder for controlled push-in core insertion, and optional graft driver. The OATS 2.0 set includes depth stop features to control the recipient site and donor plug to either 8 mm or 13 mm lengths.
