No difference in clinical outcomes between portable navigation and conventional instrumentation in total knee arthroplasty: A randomised trial.

Background: Portable accelerometer-based navigation devices (PAD) in total knee arthroplasty (TKA) have been proposed to combine the alignment precision of computer navigation with the efficiency of conventional instrumentation (CON). The aim of this study was to determine if PAD was more effective than CON in TKA in improving clinical outcomes at medium term follow-up.

Methods: Participants undergoing primary TKA were randomly assigned to either PAD or CON.
