title: Functional results of navigated minimally invasive and conventional total knee arthroplasty: a comparison in bilateral cases.
abstract: This prospective study aimed to compare the clinical and radiologic results achieved using navigation-assisted minimally invasive surgery (NA-MIS) and conventional techniques in 42 patients who underwent bilateral total knee arthroplasty (TKA), with a minimum 1-year follow-up. Patients who underwent NA-MIS TKA showed better Hospital for Special Surgery (HSS) Scores and Western Ontario MacMaster (WOMAC) total scores for up to 6 months postoperatively than patients who underwent conventional TKA, and lower WOMAC pain score for up to 9 months postoperatively. Range of motion (ROM) was comparable in both groups at all times. More patients preferred the NA-MIS procedure to the conventional procedure. Radiologic results for the NA-MIS group showed fewer outliers than did results for the conventional group, but not in mean values.
