Allograft OATS®

Allograft OATS® Technique
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.
BioPatella™ OATS® Instrument Set
The BioPatella Instrument Set is the new standard for restoration of the articular surface of the patella when presented with oblong cartilage defects involving a significant amount of the patellar articular surface. Through a series of precisely designed cutting instruments, surgeons can replace damaged cartilage with a single, elliptical piece of viable, hyaline cartilage. The BioPatella instruments were designed to match the natural curvature of the patella to resurface the entire functional articular surface. Multiple sizes allow flexibility for the surgeon to adjust to the width and length of the cartilage defect and to ensure proper restoration of the articular surface with a single osteochondral allograft.
BioUni® OATS® Instrument Set
The BioUni OATS Instrument Set is the new standard for restoration of the articular surface when presented with elongated cartilage defects in the medial femoral condyle. Through a series of precisely designed cutting instruments, surgeons can replace damaged cartilage with a single, elliptical piece of viable, hyaline cartilage.
