Osteochondral Grafting: Effect of Graft Alignment, Material Properties, and Articular Geometry
Osteochondral grafting for cartilage lesions is an attractive surgical procedure; however, the clinical results have not always been successful. Surgical recommendations differ with respect to donor site and graft placement technique. No clear biomechanical analysis of these surgical options has been reported. We hypothesized that differences in graft placement, graft biomechanical properties, ...
متن کاملEffect of graft height mismatch on contact pressures with osteochondral grafting of the talus.
BACKGROUND Osteochondral allograft transplantation is technically demanding. It is not always possible to place the surface of the graft perfectly flush with the surrounding cartilage. One must often choose between placing at least some portion of the surface of the graft slightly elevated or recessed. The effect of this choice on joint contact pressure is unknown. PURPOSE This study was unde...
متن کاملMaterial Properties of Osteochondral Constructs and Biphasic Finite Element Models of Dynamic Loading for Articular Cartilage Tissue Engineering
INTRODUCTION The poor intrinsic healing capacity and a lack of effective clinical repair strategies for articular cartilage has generated great interest in the engineering of articular cartilage replacement tissues (e.g., [1,2]). Agarose hydrogels provide a 3D environment conducive to such tissue-engineering endeavors, as it maintains chondrocyte phenotype and allows for the development of a fu...
