摘要：

Purpose The purpose of this study was to clarify the difference in implant alignment between the direct anterior approach (DAA) and the anterolateral approach in the supine position (ALS). Methods A retrospective comparative study consisted of 215 consecutive primary total hip arthroplasties using tapered polished and straight cemented-stems via two different minimally invasive approaches (DAA group in 106 hips and ALS group in 109 hips). Results The cup radiographic anteversion angle was significantly lower in the ALS group than in the DAA group (12.9 degrees versus 16.9 degrees, p = 0.001). The frequency of the safe zone tended to be more favourable in the ALS group than in the DAA group (95% versus 87%, p = 0.052). Stem alignment in the sagittal plane was significantly better in the ALS group than in the DAA group (84% versus 71%, p = 0.022). Conclusions Both cup and stem alignments were better in the ALS group than the DAA group.
