Background The aim of this study was to validate the effectiveness of neck‐cut patient‐specific surgical guides (PSGs) for femoral component implantation in total hip arthroplasty (THA) through the anterolateral approach compared with that without PSG. Methods A total of 32 fresh cadaveric hips were included. Anatomical stem implantation with wide‐base‐contact PSG (AWP group) and without PSG (control group) were compared. The absolute errors between preoperative planning and PSG setting (E1), as well as those between preoperative planning and postoperative component implantation (E2) were evaluated using CT. Results The E1/E2 values of AWP were 0.9±0.3°/0.6±0.6° in the coronal plane, and 1.7±0.8°/1.0±0.9° in the sagittal plane, and 1.0±0.6 mm/1.0±1.1 mm for the medial height. The E2 value in the sagittal plane ( P =0.037) and the medial height ( P =0.011) of AWP were significantly smaller than those of control group. Conclusions The neck‐cut PSG through the anterolateral approach is effective for femoral component implantation.
