Computer assisted navigation in total knee arthroplasty: comparison with conventional methods.
Journal of Arthroplasty 2005 October
The success of knee arthroplasty is dependent on many factors. Postoperative extremity and component alignment are important determinants of outcome and longevity. Malalignment (>3 degrees ) results in higher failure rates. Computer-assisted navigation devices were developed to improve implant positioning. This study evaluated the early outcomes of a high-volume fellowship-trained surgeon relative to component positioning and limb alignment using an image-free navigation system. The navigation group consisted of 116 consecutive patients, and the conventional group consisted of 51 consecutive patients. The postoperative mechanical axis was within 3 degrees of neutral mechanical alignment in 95% of the navigation cases vs 84% of the conventional cases (P < .02). The range of the alignment and component position measurements narrowed, and the undesired outliers decreased. Accuracy was improved with navigation. Navigation was a viable device to improve the outcome of total knee arthroplasty relative to limb and component alignment.
