AAOS 2016: Navigated TKA by experienced surgeon leads to improved function and alignment .
Does the Use of Navigation by an Experienced Surgeon Improve the Outcomes of Primary Total Knee Arthroplasty
240 patients scheduled for total knee arthroplasty were randomized to undergo the procedure with either image-free navigation or standard instrumentation. The purpose of this study was to investigate whether TKA performed by experienced surgeons via image-free navigation would be associated with significantly improved prosthesis/limb alignment and functional scores. Results demonstrated that patients in the image-free navigation group had significantly improved pain, function sub scores and alignment values, as a well as a significantly decreased number of knee alignment outliers postoperatively.
