Autograft OATS (Osteochondral Autograft Transfer System) is an excellent procedure for the repair of small osteochondral defects of the knee or ankle. Surgeons concerned about possible donor site morbidity caused by leaving the donor site sockets open may now use specially designed Allograft Plugs to fill the donor site and promote natural bone healing for a complete biologic repair.
Articular allografts provided through Arthrex are processed as fresh allografts with viable chondrocytes. These grafts are used in resurfacing procedures in the knee, shoulder, hip, foot and ankle. Arthrex offers numerous different fresh articular allograft types to meet the needs of the patient and surgeon.
Talus OATS® Set
The Talus OATS® Instrumentation facilitates harvesting of small diameter osteochondral/hyaline cartilage cylinders from an allograft bone. The core is made by placing the 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.
