title: Total knee arthroplasty with a novel navigation system within the surgical field.
abstract: Total knee arthroplasty is a common procedure, and current navigation systems are gradually gaining acceptance for improving surgical accuracy and clinical outcomes. A new navigation system used within the surgical field, iAssist, has demonstrated reproducible accuracy in component alignment. All orientation information is captured by small electronic pods and transmitted via a local wireless network, which directs the surgical workflow automatically to the femoral and tibial resection instruments. This simple and accurate navigation system used completely in the surgical field, without optical trackers or preoperative imaging, seems to be the latest generation of smart instrumentation for total knee arthroplasty.
