Abstract
Introduction: The purpose of this study was to assess the efficacy and complications associated with revision hip arthroplasty undertaken in patients under the age group of 55 years.
Methods: A review of our institutions revision hip database showed that 430 revision hip arthroplasties undertaken over the past 9 years had a minimum follow up of 2 years. Of this 84 (56 female, 38 male) patients were under 55 years of age (range 2 to 8 years). The index procedures were preformed at an average age of 46 years (range 15 years to 54 years). The single major etiology of failure was aseptic loosening (74%), followed by infection (8%) and recurrent dislocation (7%). In majority of cases uncemented implants were used at revision surgery (91% femoral stem, 100% acetabular cups). Bone grafts were necessary in 39% of cases.
Results: There was 1% incidence of DVT requiring treatment and 1% incidence of deep infection requiring a further revision hip surgery. There were no cases of dislocation in this series. At final follow up satisfactory progress was noted in all cases with a significant improvement in Harris hip score (p < 0.05).
Discussion: In conclusion, revision of hip arthroplasty in patients below 55 years is associated with improvement in function and patient satisfaction. They perform better than older cohorts but not as good as primary THRs. The complication profile is comparable in the two groups.
