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

Pathological conditions affecting the hip and knee joints occupy a particular place amongst the important orthopaedic entities affecting the extremities. On the one hand they are relatively frequent and on the other they mean for the patient limitation of his ability to walk, because of their considerably detrimental effects. A purposeful basic treatment of these joint diseases (and here osteoarthritis takes pride of place) is only possible if it stems from a reliable biomechanical analysis of the normal and patho logical stressing of the joint in question. Whilst the situation in the hip can be considered to be fundamentally clarified, a com prehensive representation of the knee is still lacking particularly when taking into account the latest knowledge of biomechanics. Recently our concepts of the kinematics of the knee have been completely changed, but the clinically important question of articular stressing remains unanswered. Dr. Maquet has carried out pioneer work in this field for some years in adapting, by analogy, to the knee joint, principles already accepted for the hip joint. Since the knee is not a ball and socket joint, a complicated problem arises for which new thoughts are necessary. The results of the numerous operations carried out by Dr. Maquet according to the biomechanical con siderations, demonstrate that his thinking is fundamentally correct. Above all, it is here again proven (as earlier in the case of the hip) that healing of osteoarthritis depends decisively on reducing and evenly distributing joint pressure.

The Multiple Ligament Injured Knee: A Practical Guide to Management includes the most developed knowledge needed to successfully diagnose and treat knee ligament injuries. This thorough work presents anterior and posterior cruciate and collateral ligament anatomy and biomechanics along with non-invasive methods for diagnosing the extent of injury, such as radiographic and arthroscopic evaluation. Various injuries are discussed in addition to useful treatment techniques, including arthroscopic reconstruction, posterolateral and posteromedial corner injury and treatment, assessment and treatment of vascular injuries, assessment and treatment of nerve injuries, rehabilitation, and post-operative results. Each of these clearly written chapters is accompanied by a wealth of line drawings and photographs that demonstrate both the surgical and non-surgical approaches to examination and treatment.

Worldwide experience with the Lcs• mobile bearing total knee prosthesis has been unpar alleled both in terms of enduring popularity and outstanding long-term clinical results. Buechel and Pappas's design was based on the principles of; restoring anatomical joint function to as near normal as possible, minimising contact stresses to avoid wear and darn age to the bearing surfaces. and finally the idea that constraint should refiect the need for mobility, to avoid shear stresses and loosening of the implant. In 1977, the LCS® knee was implanted by Dr. Frederick Buechel. This was the first mobile bearing, tri-compartmental knee implant. This was also the first to successfully address the key issues ofloosening, wear and patello-femoral problems associated with earlier designs. The unique design solution was the creation of a common articulating geometry for the tibia and patella on the distal femoral surface. This resulted in a tibial and patellar articulation that was mobile in nature, but with an identical radius of curvature and conformity. The mobile bearing concept was considered sufficiently novel and unproven that the US FDA (Food & Drug Administration) required that it be validated in an Investigational Device Evaluation (IDE). An FDA IDE study involving 25 US surgeons was initiated in 1981. Validation of the clinical success of the device in this study resulted in FDA approval of the LCS, Knee (for cemented, tri-compartmental use) in 1985.

This book presents a fundamental basic overview of orthopedic biomechanics in sports medicine, with a special focus on the current methodologies used in modeling human joints, ligaments, and muscle forces. The first part discusses the principles and materials, including the use of finite element analysis (FEA) to analyze the stress-strain response in the implant-bone interface and design. The second part focuses on joint-specific biomechanics, highlighting the biomechanics of the knee and shoulder joints, their modeling, surgical techniques, and the clinical assessment of joint performance under various kinematic conditions resulting from different repair techniques. Written by international experts working at the cutting edge of their fields, this book is an easy-to-read guide to the fundamentals of biomechanics. It also offers a source of reference for readers wanting to explore new research topics, and is a valuable tool for orthopedic surgeons, residents, and medical students with an interest in orthopedic biomechanics.​

Consists of the proceedings of the 4th International Seminar on Biomechanics.
