OATS is an abbreviation for a procedure where a core of healthy cartilage and bone is taken from an unimportant area of the knee to replace a more important damaged area.

 

True cartilage

By transferring a core of healthy cartilage together with the underlying bone, the area should heal well and be covered by true cartilage, rather than fibroscartilage, which often is the result of other repair procedures such as ACI.

Synonyms: 
Osteoarticular transfer system
Osteochondral Autograft Transfer System
Osteochondral Autologous Transfer System
