This book describes in full detail the surgical principles and technology of Total Knee Arthroplasty (TKA), providing evidence-based data on the biomechanics of the knee joint and biomaterials in arthroplasty. Starting the chapters with the history and anatomy, the book expands its focus on important issues such as implant designs of articular geometry and ligament substitution. It describes the thorough procedures of surgery from planning, operation, discussion on how to improve the range of motion, postoperative rehabilitation and also patient satisfaction. In chapters describing the surgical procedures, and approaches, step-by-step surgical techniques are shown to manage various severe deformities. Also, the clinical relevance of surgical techniques including soft tissue balancing and alignment of the components and computer-simulated studies are of importance to highlight. Advances in Total Knee Arthroplasty invite authors who are surgeons who have extensive experience in severely deformed joints. This book is collaborated with the Japanese Replacement Arthroplasty Society (JSRA), and it is an informative material for collecting academic insights for arthroplasty surgeons and orthopaedic residents. The translation was done with the help of artificial intelligence. Subsequently, human revisions were made, mainly in terms of content. Subsequently, stylistic revisions were made by a specialized copy editor.
