A case control study of cemented acetabular total hip arthroplasty components in patients less than 50 with 5-year minimum follow-up

Abstract

Background

This study investigates the outcomes of cemented sockets in young patients (<50 years) requiring a total hip replacement (THR) compared to older patients (>50 years) having the same procedure, under the same surgeon between June 2005 and May 2009.

Methods

Prosthesis survivorship rates, patient outcomes and radiological findings were compared between a consecutive series of 56 young patients (mean 42, range 25-49) and 56 older patients (mean 69, range 53-81) that underwent a primary THR using a cemented Stryker® Exeter™ Contemporary™ flanged cup. The minimum follow-up was 5 years.

Results

No significant difference was observed between the groups’ Oxford Hip Scores (p = 0.078) or satisfaction scores (p = 0.67). Worst case scenario analysis for revision, failure or lost to follow-up showed 94.6% survival in the <50 year olds and 92.9% survival in the >50 year olds at 5 years. This study demonstrates no significant difference in patient outcomes, survivorship or radiographic findings at a minimum of 5 years between patients <50 years old and those >50 years old undergoing THR with a cemented socket.

Conclusions

We believe the current trend towards uncemented cups may be driven by marketing rather than by evidence of improved outcomes. Cemented sockets provide very good outcomes for patients of all ages.
