title: Functional impact of navigation-assisted minimally invasive total knee arthroplasty.
abstract: The functional results of 47 navigation-assisted minimally invasive total knee arthroplasties (TKAs) were compared with results of 50 conventionally performed TKAs with a minimum 1-year follow-up. Navigation-assisted minimally invasiveTKA showed better functional results than conventionally performed TKA at 1 year after surgery with regard to the Hospital for Special Surgery (HSS) score, Western Ontario and McMaster Universities (WOMAC) pain and function score, flexion range, and less outliers of leg and component alignment. Among the bilateral cases (one side by navigation-assisted minimally invasive TKA and the other side by conventionally performed TKA), more patients preferred the navigation-assisted minimally invasive side to the conventionally performed side.
