Abstract Background The surgical approach impacts the outcomes and recovery after total hip arthroplasty (THA), and approaches may affect the stem positioning. Contrary to the general concept of minimally invasive surgery, the direct anterior approach (DAA) results in more intraoperative blood loss. Therefore, the objective of this study was to compare stem positioning and hidden blood loss (HBL) among three surgical approaches: the minimally invasive DAA, Orthopadische Chirurgie Munchen (OCM), and the traditional posterolateral approach (PLA). Methods A total of 201 patients undergoing their first non-cemented THA using the DAA, OCM, and PLA were included in the study. General demographic data, stem alignment, and blood loss were evaluated. Specific comparison measurements included femoral neck anteversion, femoral stem anteversion, alignment of the stem in coronal and sagittal planes, proximal and distal medullary ratios, and femoral offset. Blood loss was measured by calculating Intraoperative Blood Loss ( IBL), visible blood loss (VBL), and hidden blood loss (HBL). Results There were no significant differences in age, gender, body mass index, preoperative diagnosis, or femoral Dorr classification among the three groups. The mean surgical time was longer for the DAA and OCM compared to the PLA (P
