This open access book describes and illustrates the surgical techniques, implants, and technologies used for the purpose of personalized implantation of hip and knee components. This new and flourishing treatment philosophy offers important benefits over conventional systematic techniques, including component positioning appropriate to individual anatomy, improved surgical reproducibility and prosthetic performance, and a reduction in complications. The techniques described in the book aim to reproduce patients’ native anatomy and physiological joint laxity, thereby improving the prosthetic hip/knee kinematics and functional outcomes in the quest of the forgotten joint. They include kinematically aligned total knee/total hip arthroplasty, partial knee replacement, and hip resurfacing. The relevance of available and emerging technological tools for these personalized approaches is also explained, with coverage of, for example, robotics, computer-assisted surgery, and augmented reality. Contributions from surgeons who are considered world leaders in diverse fields of this novel surgical philosophy make this open access book will invaluable to a wide readership, from trainees at all levels to consultants practicing lower limb surgery

The introduction of total joint arthroplasty throughout the world has contributed manifold benefits to patients who suffer from joint diseases. Concurrently, however, there has been an increase in revision surgery. Many orthopedic surgeons agree that durability of prostheses is an eternal problem. In particular, periprosthetic osteolysis recently has been identified as one of the serious problems affecting prosthetic dura bility. To improve durability, osteolysis and many other problems must be investi gated and solved both experimentally and clinically with respect to such aspects as prosthetic material, design, and biological and biomechanical behavior. This book comprises 37 papers that were presented by orthopedic surgeons and biomedical engineers at the 28th Annual Meeting of the Japanese Society for Replace ment Arthroplasty, held in March 1998 in Kanazawa, Japan. The volume is thus a compilation of the latest knowledge about the pathogenesis and reduction of osteolysis and wear, newly developed total hip prostheses, and other current topics of total knee arthroplasty. We earnestly hope that this book will be of benefit to clinicians and researchers, and that it will contribute to the creation of more durable total joint prostheses in the future.

This book is published open access under a CC BY 4.0 license. White Paper on Joint Replacement This White Paper details the status of hip and knee arthroplasty care in Germany. Hip and knee replacements are amongst the most frequently performed procedures and usually become necessarily due to age-related wear of the joint, osteoarthritis and fractures of the femoral neck. In light of demographic change, demands with regard to standards of care and the procedures are likely to rise. Contents • This White Paper contains information on indications, procedures, health economic aspects and the healthcare system stakeholders involved. • It portrays current developments with regard to the prevalence of hip and knee arthroplasty, the healthcare situation and quality of care within the chain of medical care. • This book is complemented by a chapter assessing the current situation from an expert perspective with contributions from renowned experts in the fields of science, medical technology and medical practice. This book addresses people involved in shaping and representing the healthcare system from a variety of fields including medical professions, health insurances and health sciences as well as journalists and patient representatives.

It has been a pleasure to comply with requests to publish this book in English. During the intervening years, there has been little to add to our views as to the best management of acetabular fractures, but an additional chapter has been incorporated comprising recent findings in our patients and slight changes in emphasis on the indications for operations. Additionally, having recognised that one of the greatest difficulties in this method of treatment lies in the pre-operative assessment of the standard radiographs, we have prepared a short series of radiographs which the reader may find advantageous for study. We are grateful to Mr. Reginald Eison who has translated and revised the French edition. Considerable alteration of the text and the general presen tation was necessary in order to make the material palatable in English. Our thanks are due to our new publishers, Springer-Verlag, for their keen interest and skill. E. LETOURNEL R. JUDET Preface to the French Edition It is a long time since we first attempted surgical treatment of fractures of the acetabulum accompanied by displacement, with the aim of restoring perfect articulation. Such treatment demands an exact reconstitution of the anatomy of the acetabulum and pelvic bone. This volume comprises an account of our efforts to assess the place of open reduction and internal fixation of displaced fractures of the acetabulum. The principal aim is simple: the perfect restoration of the articular surface and the associated bony architecture.

The incidence of total hip arthroplasty is increasing in number because of successful outcomes. Although technically challenging, once mastered a hip replacement is one of the most gratifying surgeries for both patient and surgeon. This book covers some of the most important aspects of hip replacement surgery. These include preoperative planning, anesthesia, classification systems, management of proximal femur fractures, anterior approach, complications, and rehabilitation aspects of hip arthroplasty. The book is intended for arthroplasty surgeons, anesthetists, and physical therapists who will find the book useful in parts and as a whole if they deal with arthroplasty cases on a regular basis. Experience-based narration of various subjects by authors ensures that first-hand experience is passed on to readers in a simple, easy-to-understand manner.

Written by leading experts from the Mayo Clinic, this volume of our Orthopaedic Surgery Essentials Series presents all the information residents need on hip, knee, shoulder, and elbow reconstruction in adults. It can easily be read cover to cover during a rotation or used for quick reference before a patient workup or operation. The user-friendly, visually stimulating format features ample illustrations, algorithms, bulleted lists, charts, and tables. Coverage of each region includes physical evaluation and imaging, evaluation and treatment of disorders, and operative treatment methods. The extensive coverage of operative treatment includes primary and revision arthroplasty and alternatives to arthroplasty.
