In joint replacement surgery with suboptimal bone, allograft materials are often used to achieve biological fixation of the metallic implant to the host bone and reducing the implant fixation time. The most commonly used techniques are cemented and hydroxyapatite (HA)-coated metallic implants. Typically, HA coatings are suggested for patients with better bone stock, whereas recommended implant fixation process for most other osteoporotic patients is bone cements. In general, there is a long-standing need to improve the performance of hip and other devices for longer in vivo implant lifetime that can help in reducing the number of revision surgeries, as well as minimizing physical and mental trauma to the patient. To achieve these goals, it is important to understand the mechanical and biological properties of coatings that can influence not only its short- and long-term bioactivity but also life span in vivo. Over the years, it has been recognized that the stability of a coated implant is governed by its physical and mechanical properties. A coating that separates from the implant provides no advantage over an uncoated implant and undesirable due to problems with debris materials, which can lead to osteolysis. Therefore, it is important to properly characterize the coated implants in terms of its physical and mechanical properties. In this chapter, specific details on coating characterization techniques including sample dimensions, sample preparation, experimental procedure and data interpretation are discussed. In particular, the standards and requirements of regulatory organizations are presented elucidating the significance and use of each characterization. It is important to appreciate that mechanical properties of coatings can only be determined with certain coating specification such as coating thickness. This chapter is designed even for non-experts to follow mechanical property characterizations of coatings on medical implants.

Bioengineers need a thorough grounding in biocompatibility - the biological performance of materials. Until now, there were no publications suitable for a neophyte in the field; prior publications were either not comprehensive or focused on rather narrow interests. Drawing on the author's 35 years of experience as a teacher, researcher, and consultant in biomaterials science and engineering (BSE), Biological Performance of Materials: Fundamentals of Biocompatibility, Fourth Edition focuses primarily on principles of biological performance at a relatively fundamental level, analyzing interactions between living organisms and nonliving materials used in medical devices - the subject that sets BSE apart as a distinct field of investigation. Following an introductory section, the book is divided into three sections: the material response to biological systems, host response to biomaterials, and test methods for determining biological response in vitro as well as in animal models and clinical settings. Supplemental "Interparts" summarize the physical properties of commonly used metallic, polymeric, and ceramic biomaterials. They also provide a guide to understanding the clinical performance of implanted biomaterials.

Despite the huge impact that biomaterials have had on patients' quality of life, improvements in device performance and the development of alternatives to augment available therapies are continuously being sought. This book explores the development and application of biomaterials over the past 25 years, examining the current clinical demand, the scientific rationale, and the technical challenges to be overcome. Furthermore, this book introduces the blood components involved in hemostasis and thrombosis, followed by the common biomaterials applied in blood-contacting devices. The complications induced by the interactions between blood and biomaterials is also briefly addressed, as well as the commonly used techniques for improving biomaterials' hemocompatibility. In addition, the authors give some valuable insight into calcium orthophosphate cements and concretes, as excellent biomaterials suitable for both dental and bone grafting application. Despite the growth of potential hydrogel based therapies, the route to market for new products is constrained by the need to develop an appropriate regulatory and metrological framework under which they will be assessed. This book outlines the role that metrology has to play in the regulation of emerging hydrogel-based therapies and detail possible strategies for assessing their safety and effectiveness. Other chapters examine the surface of CoCrMo alloy prior and after exposure into different solutions simulating oral conditions, recent research on delivery of gold nanoparticles inside the cells and their potential applications in nanomedicine, and the widely used biomedical applications for hydrogels.
