dc.description.abstractIn total knee arthroplasty TKA intramedullary and extramedullary tibial alignment guides are not proven to be highly accurate in obtaining alignment perpendicular to the mechanical axis in the coronal plane The objective of this study was to determine the accuracy of an accelerometer based handheld surgical navigation system in obtaining a postoperative tibial component alignment within 2 of the intraoperative goal in both the coronal and sagittal planes A total of 151 TKAs were performed by 2 surgeons using a handheld surgical navigation system to perform the tibial resection Postoperatively standing anteroposterior hip to ankle radiographs and lateral knee to ankle radiographs were performed to determine the varus valgus alignment and the posterior slope of the tibial components relative to the mechanical axis in both the coronal and sagittal planes Findings showed that 95 3 of the tibial components were placed within 2 of the intraoperative goal in the coronal plane and 96 1 of the components were placed within 2 of the intraoperative goal in the sagittal plane Overall mean postoperative lower extremity alignment was 0 3 2 1 with 97 of patients having an alignment within 3 of a neutral mechanical axis The handheld surgical navigation system improves the accuracy of the tibial resection and subsequent tibial component alignment in TKA It is able to combine the accuracy of computer assisted surgery systems with the ease of use and familiarity of conventional extramedullary alignment systems and the ability to adjust both the coronal and sagittal alignments intraoperatively may prove clinically useful in TKA
