Accuracy of a Novel 3D‐Printed Patient‐Specific Intramedullary Guide to Control Femoral Component Rotation in Total Knee Arthroplasty

Abstract

The short-term clinical efficacy of TKA assisted by PSI was similar to the conventional TKA. Although TKA assisted by PSI spent more time during operation, it could assist in intramedullary guide and align femoral rotation more accurately.
