Capsular management strategies in hip arthroscopy for femoroacetabular impingement syndrome: A multilevel meta-analysis.

ABSTRACT:

Purpose

To compare three capsular management strategies in hip arthroscopy (capsule preservation [CP], capsule repair [CR] and capsule unrepaired [CU]) for femoroacetabular impingement syndrome (FAIS). We hypothesized that CP and CR would provide superior outcomes compared with CU.

Methods

A systematic search of PubMed, Embase, CENTRAL and Epistemonikos was conducted up to 31 May 2025. Outcomes of CP, CR and CU were compared using a frequentist multilevel random-effects meta-analysis with restricted maximum likelihood estimation and Hartung-Knapp adjustment.

Results

Ultimately, 47 primary studies met the inclusion criteria and were included in the meta-analysis. A total of 7366 hips (7276 patients) were included across the 47 studies. These were distributed into three
