Systematic review demonstrates improved outcomes with cup-on-cup technique in severe acetabular defects, suggesting careful use.

Key Points

This systematic review aims to synthesize evidence on the cup-on-cup technique for managing massive acetabular defects in revision total hip arthroplasty.
Conducted a comprehensive literature search in PubMed, Embase, Scopus, and the Cochrane Library up to April 2025.
Included six studies assessing clinical outcomes of cup-on-cup constructs for acetabular revision with a total of 111 patients.
Used OCEBM criteria to assess methodological quality of the included studies.
The weighted mean Harris Hip Score improved from 33.6 points to 86.7 points postoperatively.
Only one study reported a 6.3% rate of aseptic loosening among the participants.
Complications included dislocation rates varying from 0% to 30% and deep infection in up to 20% of specific cohorts.
