This state-of-the-art book focuses specifically on the current and emerging uses of robotics for knee and hip arthroplasty, with an expanding market anticipated, particularly as costs drop, data emerges and surgical efficiencies improve. It is divided into four main sections. Part one covers the background and basic principles of robotics in orthopedic surgery, discussing its history and evolution, current concepts and available technologies, perioperative protocols for recovery and pain management, economic considerations, and risks and complications. The second and third parts focus on the techniques themselves for the knee and hip respectively, including unicompartmental and bicompartmental knee arthroplasty, patellofemoral arthroplasty, and total knee and hip arthroplasty utilizing Navio, Mako, iThink, Omni and ROSA Knee robots. The final section presents the emerging use of robotics in spine surgery as well as for hospital process improvement.
