"The replacement of a degenerated joint such as the hip and knee is one of the most outstanding interventions that allows the medical community to restore the patient's quality of life. However, today's patient is increasingly younger and more active and this presents a challenge for the orthopaedic community as a greater demand has been created for a longer lasting artificial joint that can allow the patient to maintain their lifestyle and thus new approaches in biotribology have been focused on this area of research. This invaluable book provides a broad introduction to the boundary conditions, developments and latest research activities already available to the surgeon and offers an insight into solutions being developed for new high performance bearings in joint replacements. The contributors are leading experts in their field and this is the first complete volume to bring together such unique insights. Orthopaedic engineers, surgeons and researchers concerned with new biomaterials would find this a vital reference volume to evaluate the latest state of research in the area."--
Joint replacement is a very successful medical treatment. However, the survivorship of hip, knee, shoulder, and other implants is limited. The degradation of materials and the immune response against degradation products or an altered tissue loading condition as well as infections remain key factors of their failure. Current research in biomechanics and biomaterials is trying to overcome these existing limitations. This includes new implant designs and materials, bearings concepts and tribology, kinematical concepts, surgical techniques, and anti-inflammatory and infection prevention strategies. A careful evaluation of new materials and concepts is required in order to fully assess the stren...
This book addresses the background and significance of the factors potentially influencing the clinical and biological outcomes of metal-on-metal hip implants. Metal-on-metal bearings were introduced and evaluated as an alternative to other bearing couples, particularly metal-on-polyethylene, due to their enhanced wear resistance as determined in laboratory testing. Initially, reports of short-term clinical outcomes were favorable and an increasing number of metal-on-metal prostheses were implanted. Subsequently, isolated case findings describing adverse tissue responses around the articulation became the harbinger of an increasing number of reports describing pseudotumors and other signific...
Fundamentals of Tribology deals with the fundamentals of lubrication, friction and wear, as well as mechanics of contacting surfaces and their topography. It begins by introducing the reader to the importance of tribology in everyday life and offers a brief history of the subject. It then describes the nature of rough surfaces and the mechanics of contacting elastic solids and their deformation under load and friction in their relative motion. The book goes on to discuss the importance of lubricant rheology with respect to viscosity and density. Then, the principles of hydrodynamic lubrication are covered with derivations of the governing Reynolds and energy equations. Applications of hydrod...
Unicompartmental knee arthroplasty (UKA) - also known as unicondylar knee arthroplasty or partial knee replacement - is an excellent surgical option for the treatment of isolated medial, lateral and patellofemoral compartment arthritis of the knee, as long term results suggest high patient satisfaction and survivability that rivals total knee arthroplasty (TKA). These procedures are well-suited for rapid recovery protocols and outpatient surgery through well-structured surgical pathways. With demand increasing for knee arthroplasty, patients presenting sooner and at a younger age, and an ever-increasing interest from patients, surgeons and payors in outpatient surgery, the demand for unicomp...

This book presents the state of the art in and offers up-to-date guidance on the treatment of knee osteoarthritis (KOA), a rapidly evolving and expanding field. Written by experts from leading institutions, it offers a comprehensive overview of this condition, from initial treatment, to surgical approaches and rehabilitation. The book covers a variety of topics, including intra-articular injection options; treatment of uni- and tri-compartmental KOA; infected, unstable and stiff total knee arthroplasty; periprosthetic fractures; and prosthetic revision. A wealth of images and cutting edge information make this book an invaluable tool for orthopedic surgeons, rheumatologists, physiatrists, physiotherapists and all healthcare workers involved in the care of these patients.
Medical tribology can be defined as the science of tribological phenomena in the human body, both those that naturally occur in the tissues or organs and those that arise after implantation of an artificial device, while biomaterials are inert substances designed to be incorporated into living systems. Biomaterials and medical tribology brings together a collection of high quality articles and case studies focussing on new research and developments in these two important fields.The book provides details of the different types of biomaterial available and their applications, including nanoparticles for biomedical applications, synergism effects during fiction and fretting corrosion experiment...
