Measurement value of pelvic and femoral parameters.

	Surgical side	Non-surgical side	Difference between surgical and non-surgical side
AO (mm)*	19.0 ± 2.4 (11.7–25.7)‡	20.1 ± 1.9 (14.2–24.8)‡	− 1.2 ± 2.7 (− 7.3 to 5.6)
FO (mm)*	22.6 ± 3.6 (14.3–32.3)‡	21.2 ± 3.4 (9.5–29.1)‡	1.3 ± 3.7 (− 8.5 to 10.4)
GFO (mm)*	41.5 ± 4.5 (29.5–52.4)	41.4 ± 4.3 (29.6–50.1)	0.2 ± 4.3 (− 11.4 to 10.2)
AFO (mm)*	22.1 ± 4.4 (10.5–34.1)	21.6 ± 4.4 (9.0–36.2)	0.5 ± 5.5 (− 1.43 to 13.7)
LLD (mm)*			− 0.4 ± 5.1 (− 12.9 to 12.6)

Negative values indicated that the length of the surgical side was longer than that of the non-surgical side.

AO acetabular offset, FO femoral offset, GFO global femoral offset, AFO anterior femoral offset, LLD leg length discrepancy.

*Mean ± standard deviation (range).

These values were adjusted to 100 cm of body height.
