Orthopaedic Implant Design and Manufacturing for Traumatic Injuries

Abstract

The overall objective of this project wis to develop a three-dimensional woven material that provides a new surface for damaged areas of localized cartilage defects. We show that welded-woven materials have dramatically improved wear resistance and that their mechanical properties are more similar to cartilage than their unwelded counterparts. Additionally, we began experiments with short-duration, nontoxic crosslinking protocols that will improve the wear resistance of cartilage. If further studies are successful, they may lead to techniques that reduce cartilage wear against engineering materials, increasing the life of implants such as the one proposed here.
