Design and Characterisation of a Multi-Layered Collagen-Based Scaffold for Osteochondral Defect Repair
Introduction Articular cartilage is a highly specialised tissue which is organised into distinct layers that vary in both structure and composition according to distance from the surface. Cartilage has a poor ability to regenerate itself and as a result, superficial damage almost inevitably leads to the development of osteoarthritis (OA). Recently, the potential of osteochondral tissue engineer...
متن کاملBiomimetic biphasic scaffolds for osteochondral defect repair
The osteochondral defects caused by vigorous trauma or physical disease are difficult to be managed. Tissue engineering provides a possible option to regenerate the damaged osteochondral tissues. For osteochondral reconstruction, one intact scaffold should be considered to support the regeneration of both cartilage and subchondral bone. Therefore, the biphasic scaffolds with the mimic structure...
متن کاملMulti-layered collagen-based scaffolds for osteochondral defect repair in rabbits.
INTRODUCTION Identification of a suitable treatment for osteochondral repair presents a major challenge due to existing limitations and an urgent clinical need remains for an off-the-shelf, low cost, one-step approach. A biomimetic approach, where the biomaterial itself encourages cellular infiltration from the underlying bone marrow and provides physical and chemical cues to direct these cells...
متن کاملPrediction of the optimal mechanical properties for a scaffold used in osteochondral defect repair.
The optimal mechanical properties of a scaffold to promote cartilage generation in osteochondral defects in vivo are not known. During normal daily activities cartilage is subjected to large cyclic loads that not only facilitate nutrient transport and waste removal through the dense tissue but also act as a stimulus to the chondrocytes. In contrast, cartilage tissue is commonly engineered in vi...
متن کاملPorous tantalum biocomposites for osteochondral defect repair
OBJECTIVES We sought to determine if a durable bilayer implant composed of trabecular metal with autologous periosteum on top would be suitable to reconstitute large osteochondral defects. This design would allow for secure implant fixation, subsequent integration and remodeling. MATERIALS AND METHODS Adult sheep were randomly assigned to one of three groups (n = 8/group): 1. trabecular metal...
