Osteochondral autograft transfer (OATS)
What is the osteochondral autograft transfer (OATS)?
Like osteochondral autograft implantation, this procedure is designed to replace the damaged articular cartilage that lines the ends of bones within a joint. However, instead of using cartilage from a deceased donor, the surgeon uses cartilage from an undamaged area of your joint to replace the damaged cartilage. As a result, this procedure is typically only used when the damage occurs in an area 10 to 20 mm in size.
