Single wedge | Anatomical | Conical | |
Combined anteversion | Femoral anteversion (Pearson’s r = − 0.295, p < 0.0001: fair inverse correlation) | Femoral anteversion (Pearson’s r = − 0.274, p < 0.0001: fair inverse correlation) | No correlations |
Offset reconstruction | No correlations | No correlations | Offset (Pearson’s r = − 0.257, p 0.0002: fair inverse correlation) |
Coronal and sagittal tilt | No correlations | No correlations | No correlations |
Canal filling | No correlations | No correlations | No correlations |
Leg lengthening | Center of rotation height (Pearson’s r = − 0.308, p < 0.0001: fair inverse correlation) | Center of rotation height (Pearson’s r = − 0.361, p < 0.0001: fair inverse correlation) | Center of rotation height (Pearson’s r = − 0.450, p < 0.0001: fair inverse correlation) |
