Abstract

Background Robotic assistance and computer navigation may improve component positioning in total knee arthroplasty (TKA), but their clinical value depends on whether radiographic gains justify additional operative time and expenditure. Objective To compare robotic-assisted TKA (RA-TKA), computer-navigated TKA (CN-TKA), and conventional jig-based TKA (JIG-TKA) with respect to perioperative efficiency, short-term clinical efficacy, mechanical-axis restoration, cost, complications, and the observed learning curve.
