The autograft OATS (osteochondral autograft transfer system) technique is an excellent procedure for the repair of small osteochondral defects of the knee. Single-use OATS instrumentation may be used to facilitate the harvest of osteochondral/hyaline cartilage cores from a donor site superior and lateral to the notch or above the sulcus terminalis. The single-use OATS 2.0 kits include depth-stop features to aid in the preparation of the core and depth of the recipient site.
