Navigation Matters: Initial Experience With Navigation for Bilateral Total Knee Arthroplasty

摘要

The purpose of this study was to evaluate the effectiveness and safety of surgical navigation for sequential bilateral total knee arthroplasty (TKA) in a single anesthetic session. We retrospectively evaluated our initial experience with navigated bilateral TKA to determine if benefits of improved consistency of implantation, decreased blood loss, and reduced systemic emboli could be identified.Two groups were compared. The investigational group had bilateral TKA using surgical navigation, and the control group had bilateral TKA using conventional instrumentation. Knee Society Scores were used for clinical evaluation and component placement, and alignment was determined using the Knee Society Radiological Evaluation protocol.
