Particulated Juvenile Articular Cartilage Allograft Transplantation With Bone Marrow Aspirate Concentrate for Treatment of Talus Osteochondral Defects

Osteochondral defects (OCDs) of the talus are potential sequelae of traumatic ankle injury and chronic ankle instability. Conservative treatment may fail thus requiring surgical intervention. Primary surgical intervention has classically entailed bone marrow stimulation, which may include drilling, microfracture, and/or abrasion arthroplasty, filling in the defect with fibrocartilage. Clinical data has revealed good short-term success but the long-term effects and follow-up have been questioned. Newer techniques, such as osteochondral autograft transfer, fresh osteochondral allograft transfer, and autologous chondrocyte implantation, have shown initial promise in restoring physiological hyaline cartilage but each procedure carries increased morbidity as arthrotomy, osteotomy, or a second procedure are often necessary. Juvenile articular cartilage allograft transplantation has shown initial promising results in treating smaller sized OCDs and restoring physiological hyaline cartilage without the increased morbidity of osteotomy or 2-step procedures. Augmentation with biological adjuncts has been shown to further aid in healing and regeneration of physiological articular cartilage. The purpose of this article is to describe a novel surgical all-arthroscopic technique for transplantation of juvenile articular cartilage allograft augmented with bone marrow aspirate concentrate for the treatment of OCDs. Level of Evidence: Diagnostic Level 4. See Instructions for Authors for a com...
