The disposable donor and recipient cutting tube sets of the Osteochondral Autograft Transfer System (OATS) facilitate harvesting of various diameter osteochondral/hyaline cartilage cylinders from a donor site superior and lateral to the notch or above the sulcus terminalis. A recipient socket, sized to the proper depth, is created in the chondral defect to accept the donor graft. The bone cylinder is inserted with a collared pin delivery system for press-fit fixation. Harvesting and insertion depth are controlled with 5 mm depth markings. Final seating of the harvested cylinder, flush with the surrounding articular cartilage, is achieved with a slightly larger diameter Sizer/Tamp.
