Radiographic accuracy in TKA with a CT-based patient-specific cutting block technique

摘要

Purpose: Patient-specific instrumentation (PSI) technology for the implantation of total knee arthroplasty (TKA) has a rising interest in the orthopaedic community. Data of PSI are controversially discussed. The hypothesis of this paper is that the radiological accuracy of CT-based PSI is similar to the one of navigated TKA published in the literature. Methods: Since 2010, all 301 consecutively performed PSI TKAs (GMK MyKnee
