Implication

Retrospective cohort study evaluates outcomes of multicup reconstruction in revision total hip arthroplasty, indicating effective management for severe defects.

Key Points

To evaluate the mid-term outcomes of the multicup reconstruction technique for severe protrusio acetabular defects during revision total hip arthroplasty.
Retrospective cohort study of 40 patients undergoing revision THA from 2015 to 2024.
Utilized trabecular metal revision shell and cemented porous hemispherical cups for reconstruction.
Follow-up averaged 61 months with survival rates assessed using Kaplan-Meier analyses.
Five-year survivorship free from acetabular failure was 94.6% (95% CI 80.0%–98.6%).
Five-year revision-free survivorship was 92.1% (95% CI 77.4%–97.4%).
Average Harris Hip Score improved to 78.0 points (range 66.5–86.7) at the final assessment.
