OATS for Osteochondral Lesions of the TalusLesions larger than approximately 150 mm² fail bone marrow stimulation treatment 97% of the time. OATS transplants genuine hyaline cartilage to replace the weakening fibrocartilage scar that microfracture produces in larger defects.Lesions larger than approximately 150 mm² fail bone marrow stimulation treatment 97% of the time.

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%.

ChondroFiller injection for ankle osteochondral lesionsChondroFiller is an injectable collagen scaffold that repairs ankle cartilage by recruiting the patient's own cells to rebuild the lesion, rather than introducing foreign cells or merely masking symptoms.ChondroFiller is an injectable collagen scaffold that repairs ankle cartilage by recruiting the patient's own cells to rebuild the lesion, rather than introducing foreign cells or merely masking symptoms.

When OATS mosaicplasty beats other ankle cartilage repairsLesions exceeding 150 mm² require OATS mosaicplasty: marrow stimulation produces fibrocartilage that breaks down within two to three years, whilst transplanted hyaline cartilage lasts decades.Lesions exceeding 150 mm² require OATS mosaicplasty: marrow stimulation produces fibrocartilage that breaks down within two to three years, whilst transplanted hyaline cartilage lasts decades.

Osteochondral Allograft for Ankle Cartilage DefectsLesions on the talus larger than 15mm fail with microfracture repair; osteochondral allograft instead restores the cartilage and bone using donor tissue, achieving 85% survivorship at ten years.Lesions on the talus larger than 15mm fail with microfracture repair; osteochondral allograft instead restores the cartilage and bone using donor tissue, achieving 85% survivorship at ten years.
