Pelvic tilt remains unchanged after periacetabular osteotomy: A single-arm multilevel meta-analysis and meta-regression.

ABSTRACT:

Purpose

Understanding changes in pelvic tilt (PT) after periacetabular osteotomy (PAO) is essential for surgical planning and outcome assessment. This study aimed to synthesise current evidence on pre- and postoperative PT and identify associated factors using meta-regression.

Methods

A systematic search of PubMed, Embase, and Epistemonikos was conducted through 31 May 2025. A single-arm multilevel meta-analysis was performed using a random-effects model to estimate mean PT values before and after PAO. Subgroup analyses examined differences based on surgical indication (DDH/BDDH vs. others) and unilateral vs. bilateral surgery. Meta-regression assessed the impact of age, sex and BMI on PT outcomes. Statistical analyses were performed using R.
