Three-dimensional printing technique has been adapted for orthopedic surgery, and a patient-specific surgical guide (PSG) has been introduced as a convenient surgical instrument and implicated in the ideal positioning of the components, including acetabular and femoral components in total hip arthroplasty (THA). PSG is designed and manufactured based on preoperative imaging data, mainly computed tomography (CT) data. PSGs for implantation in THA are classified into three types: PSG for guidewire insertion, PSG for bone cutting, and PSG for bone reaming and implant fixation. PSG positioning accuracy depends on the PSG design and surgical preparation in contact area on the bone surface. PSGs for the acetabular component, for the conventional femoral component, and for the resurfacing femoral component have been clinically used. To achieve precise implantation, precise PSG setting needs and careful surgical preparation of soft tissues are important.
