Long term results of total hip arthroplasty in younger age group: comparative analysis with young resurfacing arthroplasty patients.

Abstract

Critical analysis of 87 total hip replacement patients with 116 hips, 60 years of age and under (16 to 60), followed for five to 10 years, resulted in 89% satisfactory results and an 11% revision rate. Complications requiring revision surgery were: loss of femoral component (five hips), broken femoral compartment (two hips), loosening of both acetabular component (two hips), and loosening of acetabular component alone (one hip). Revision rate in patients 40 years and under was 15.4%, compared to 6.7% of patients 41 to 60 years of age. Complication of loosening was directly related to activity level of patients. Comparing conventional total hip arthroplasty versus resurfacing arthroplasty, the revision rate was 11% and 21.3% respectively, with shorter followup in the latter group.
