Abstract When compared to standard intramedullary and extramedullary referencing systems, computer-assisted navigation systems have been shown in multiple randomized studies to increase the accuracy of bone resections in total knee arthroplasty. Accuracy to within 1 degrees in the coronal plane resections can routinely be obtained. Recent modifications of the software programs address the problem of proper soft tissue balance. Newer techniques of bone morphing have obviated the use of preoperative imaging in most cases. Despite these advances, the systems remain somewhat cumbersome to use and costly to acquire. As these limitations are addressed, computer-assisted navigation may become a valuable part of the knee surgeon's armamentarium, especially for the patient with a deformed femur or tibia in whom conventional navigation instruments are difficult to use accurately.
