51 patients (102 knees) scheduled for same-day bilateral total knee arthroplasty were to undergo the procedure with one knee randomly assigned to be operated using the subvastus approach and the other with the medial parapatellar approach. The purpose of this study was to investigate whether patients perceived any differences (patient-reported outcome measures) and whether either surgical technique proved to be superior when assessed through physician-reported objective outcomes. Results of this study indicated that for all follow-up points, both patient-reported and physician-assessed outcomes were comparable between surgical techniques, suggesting that one technique was not significantly superior to the other for TKA.
