ACI for Ankle Cartilage DefectsMicrofracture produces fibrocartilage that deteriorates within two to three years for ankle cartilage lesions over 15 mm in diameter; autologous chondrocyte implantation regenerates more durable, hyaline-like cartilage that more closely resembles native tissue for larger defects.Microfracture produces fibrocartilage that deteriorates within two to three years for ankle cartilage lesions over 15 mm in diameter; autologous chondrocyte implantation regenerates more durable, hyaline-like cartilage that more closely resembles native tissue for larger defects.

Recovery After OATS for Ankle Cartilage RepairOATS (osteochondral autograft transfer) replaces damaged ankle cartilage and bone with a healthy graft from the knee, producing hyaline-like tissue rather than scar tissue; at ten years, graft survival reached 94.9% and functional scores improved from 51.9 to 75.3, though donor-site morbidity affected 6.7–10.8%.OATS (osteochondral autograft transfer) replaces damaged ankle cartilage and bone with a healthy graft from the knee, producing hyaline-like tissue rather than scar tissue; at ten years, graft survival reached 94.9% and functional scores improved from 51.9 to 75.3, though donor-site morbidity affected 6.7–10.8%.
