AAOS 2016: No advantage noted with subvastus versus medial parapatellar TKA .
Patient's Perception Between Subvastus and Medial Parapatellar Approach After Total Knee Replacement is not Different
50 patients scheduled for simultaneous bilateral total knee arthroplasty (TKA) had one knee randomized to the procedure through a subvastus approach, and the other knee to a medial parapatellar approach. The purpose of this study was to evaluate whether the SV approach had a significant positive effect on patient preference, patient-reported clinical outcomes, or physician-assessed objective outcome measures. The results demonstrated no significant differences between groups in patient preference at either 1 week or 1 year postoperatively. Additionally, with the exception of greater quadriceps strength at 1 week, no significant differences were noted between groups in any outcome measure.
