Patient-Specific Instruments Based on Knee Joint Computed Tomography and Full-Length Lower Extremity Radiography in Total Knee Replacement

摘要

Background:Restoring good alignment after total knee replacement (TKR) is still a challenge globally, and the clinical efficiency of patient-specific instruments (PSIs) remains controversial. In this study, we aimed to explore the value and significance of three-dimensional printing PSIs based on knee joint computed tomography (CT) and full-length lower extremity radiography in TKR.
