Osteochondral Autologous Transfer System (OATS) is a surgical procedure where a plug of bone and cartilage is cored from a relatively unimportant area of knee cartilage and used to replace damage to an important area.
The plug is a core of cartilage and bone.
The plug is 'press fit' into the prepared defect, without any fibrin glue.
One-stage OATS procedure
In an Osteochondral Autologous Transfer System the plug of tissue (osteochondral graft) is taken from the patient rather than from a donor. It is a 'one-stage' procedure, where the harvesting and the grafting are performed at the same surgery.

"The OATS procedure has traditionally been considered an open procedure. However, with the advancement of arthroscopic techniques, the procedure can now be completed arthroscopically."
