Disposable Navigation for Total Knee Arthroplasty.

Overview

Recent developments in surgical techniques and technologies have advanced accuracy and increased implant survival of total knee arthroplasty (TKA). The introduction of mechanical guides and computer-assisted navigation has improved component alignment and the ability to accurately reproduce component position. Over the past decade, computer navigation and intraoperative guides have been introduced to help control surgical variables and overcome the limitations and inaccuracies of traditional mechanical instrumentation. The use of disposable navigation increases the accuracy of component placement while decreasing the incidence of outliers compared to standard mechanical guides without the need for a large computer console in the operating room.
