Box plots of postoperative abduction (a) and anteversion (b) angles of the acetabular component in the previous version group and new version group. The mean postoperative cup abduction of the acetabular component was 39.2° ± 4.6° (range, 27° to 50°) in the previous version group and 40.3° ± 4.9° (range, 26° to 53°) in the new version group. The mean postoperative cup anteversion was 14.6° ± 6.1° (range, 1° to 27.5°) in the previous version group and 15.8° ± 5.6° (range, 6.7° to 29.5°) in the new version group. There were no significant differences between the previous version group and new version group with regard to mean cup abduction and anteversion (P = 0.218, 0.334). Significant differences in variation between groups were not indicated for cup abduction and anteversion (P = 0.767, 0.870). Results of previous version group were from our previous study [24]
