Osteochondral autografting has been reported successful in canine, equine and human cases. Autografting has been used to treat osteochondrosis, trauma, cystic lesions and other articular defects in a variety of joints. Without treatment, these conditions are typically associated with pain, lameness, decreased range-of-motion, and progressive osteoarthritis.

The OATS (Osteochondral Autograft Transfer System) facilitates templating of the defect, harvesting of 6, 8, and / or 10 mm cylindrical osteochondral autografts, and preparation of the recipient socket(s) for press-fit fixation of one or more grafts.

The cylindrical graft is harvested and then trimmed to its optimal depth (at least 8 mm). Recipient sockets are prepared with a guide pin and size matched cannulated reamer to the exact depth of the graft.

The size-specific system includes a marking pen w/ruler, guide pin, Cannulated Headed Reamer, dual-sided Alignment Rod, Donor Harvester with Core Extruder, clear graft delivery tube, oversized Tamp, optional graft driver for tap-in insertion, and core extractor for removal and revision or replacement of the graft.

Two critical aspects of the OATS procedure involve the careful harvest of the graft from the optimal donor sites and accurate recipient bed preparation. Donor site choice is based on availability of nonarticulating, nonweight-bearing hyaline cartilage with adequate thickness and surface contour.
