Revision total hip arthroplasty in younger patients: indications, reasons for failure, and survivorship.

Abstract

Increasing numbers of total hip arthroplasty (THA) procedures are being performed on younger patients, and the incidence of revision THA in this population is also increasing. The goals of our retrospective study were to survey the surgical indications and reasons for failure and survivorship of revision THA in patients aged < 50 years. We identified 139 cases of revision THA performed over a 6-year period in patients aged < 50 years. The most common reason for revision was aseptic loosening, followed by acetabular liner wear with or without osteolysis. We found an overall 10-year survivorship of 76%. When survivorship was stratified by the indication for revision surgery, revision for wear demonstrated the best 10-year survivorship, while revision for instability or infection exhibited poor survivorship.
