This study presents a novel approach to revising failed medial unicompartmental knee arthroplasty into kinematically aligned total knee arthroplasty using an augmented reality (AR) system (NextAR by Medacta International). Traditional methods involve mechanically aligned TKA, which can be complex and often requires additional components like stems and augments. The proposed technique builds on calipered manual method by integrating AR-based navigation to enhance precision during surgery, particularly in maintaining the patient’s native joint line and soft tissues behaviour. The procedure includes preoperative three-dimensional planning and intraoperative adjustments based on real-time collateral ligament elongation data. This AR-assisted technique aims to reduce the technical challenges associated with UKA revisions, offering potential benefits in alignment accuracy and soft tissue management.
