Comparison of artificial intelligence-assisted or CT-based 3-dimensional preoperative planning with conventional 2-dimensional templating in total hip arthroplasty
Background: Implant planning is essential for prosthesis matching in total hip arthroplasty (THA). Conventional 2-dimensional (2D) templating has limitations in predicting implant size. Recently, artificial intelligence (AI)-assisted 3-dimensional (3D) planning and computed tomography (CT)-based 3D planning have been increasingly applied clinically. However, 3D planning methods remain heterogeneous, making the evidence difficult to interpret. This study aimed to systematically evaluate AI-assisted or CT-based 3D pr …
