OATS stands for which orthopedic procedure?

• A. Osteochondral Autograft Transfer System
• B. OsteoAllograft Transfer Solution
• C. Osteoarthritic Treatment System
• D. Osteo Allograft Transfer Sterilization

Answer: (A)

OATS is an osteochondral autograft transfer procedure used to treat focal articular cartilage defects, most often in the knee. It involves harvesting cylindrical osteochondral plugs from a nonweight-bearing region of the patient’s own knee and transplanting them into the defect to recreate a smooth articular surface. Because the graft is autologous, there’s no risk of immune rejection or disease transmission associated with allografts. The implanted plugs aim to restore hyaline cartilage–like tissue rather than fibrocartilage, improving durability and function when used for suitable defects. The other options describe allograft-based concepts or unrelated terms and do not reflect the autograft transfer approach.
