This book discusses total knee arthroplasty (TKA) with respect to the status of the cruciate ligaments in the replacement. The evolution of knee replacements, along with basic anatomy and kinematics of the knee, open up the presentation, with subsequent chapters on the present state of the art for each design with respect to the cruciate ligaments. The next chapters describe current and developing surgical techniques and technologies for various partial and total knee arthroplasty, including robotic and artificial intelligence techniques. Concluding chapters cover physical therapy following TKA, comparative kinematic analysis of modern designs, and future considerations for management. With authors from a variety of backgrounds - biomechanics experts, arthroplasty surgeons, rehabilitation physicians and physical therapists - this book will appeal to a broad audience including surgeons in practice, residents in training, surgeons involved in new knee designs, biomechanical engineers, and the physical therapists. .
