Utilization of Jumbo-Sized Cups in Conjunction With Dual-Mobility Constructs Does Not Increase Risk of Re-Revision in Revision Hip Arthroplasty.

ABSTRACT:

Background

Dual-mobility (DM) articulations are increasingly used in revision total hip arthroplasty (THA) to reduce instability, but their effectiveness in conjunction with jumbo cups is unclear. This study evaluated the risk of all-cause and instability-related re-revision when DM articulations were used with jumbo vs standard cups in revision THA.

Methods

A retrospective review included 199 revision THA patients with DM articulations: 156 with regular cups and 43 with jumbo cups (≥62 mm for females, ≥66 mm for males). Exclusion criteria were cup-cage constructs, cemented DM liners in pre-existing cups, and tumor cases. The primary outcome was re-revision, with focus on instability. Student's t-test compared revision rates, and multivariable logistic regression with
