Curved periacetabular osteotomy (CPO) is one of the periacetabular osteotomies for the treatment of acetabular dysplasia. Several complications have been described after CPO. This study aimed to investigate the leg length change (LLC) after CPO and its impact on the clinical outcomes.

This study looked back at 70 consecutive hips from 67 patients with symptomatic acetabular dysplasia who had CPO. Anteroposterior radiographs were used to determine preoperative and postoperative leg lengths, and clinical results were assessed using the Harris hip score (HHS) and the Medical Outcomes Survey 36-item Short Form Health Survey (SF-36).

Results:
--The mean LLC (and standard deviation) after CPO was -0.08 ± 3.10 mm. The mean HHS significantly improved from 73.5 points to 91.9 points.

--The physical component and role component scores of SF-36 significantly improved from 35.1 to 46.1 and from 39.5 to 47.0, respectively.

--No significant differences were found between the pre- and postoperative mental component scores of SF-36.

--Additionally, among 70 hips, 35 hips exhibited leg length elongation (0 to plus 6.82 mm) after CPO, whereas 35 hips exhibited leg length shortening (0 to minus 6.23 mm).

--No significant differences were found in HHS and SF-36 between the leg elongation group and leg shortening group.

Conclusively, the mean LLC after CPO was -0.08 ± 3.10 mm, and this difference had no impact on postoperative clinical outcomes.
