Meta-Regression Analysis of the Association Between Acetabular Cup Positioning and Functional Outcome for Patients With Iliopsoas Impingement Syndrome After Total Hip Arthroplasty.

ABSTRACT:

Background

To examine the association between acetabular cup positioning and functional outcomes, measured with Harris Hip Score (HHS), in IPI patients after THA.

Methods

A literature search was conducted in PubMed, CENTRAL, Epistemonikos, and Embase up to November 30, 2024. A multilevel random-effects meta-analysis was performed with a restricted maximum likelihood heterogeneity estimator and Hartung-Knapp adjustment. Logistic regression on pooled data identified acetabular cup inclination and anteversion cut-offs associated with IPI, we performed logistic regression analysis on pooled data from the included studies.

Results

Ultimately, 32 studies with overall 1755 patients were included. The non-IPI subgroup (mean: 91.5; confidence interval [CI]: 88.2-94.9; I^2<
