| Résumé : |
While revision of total hip arthroplasty (THA) is being performed with increasing frequency, outcomes of repeated revisions have been rarely reported in the literature. The purpose of this study was to report mid-term outcomes of re-revision of failed revision THA acetabular components. We performed at least two revisions of the failed acetabular component in 57 patients (57 hips) between August 1996 and April 2008. Of these, 15 patients with infection were excluded and one died before 4-year evaluation. The final study cohort consisted of 41 patients (41 hips) with a mean age of 55.5 years (range, 37 to 82). Preoperative acetabular bone defects was classified as Paprosky Type IIA in 4 hips, Type IIB in 6, Type IIC in 9, Type IIIA in 16, and Type IIIB in 6. The mean duration of follow-up was 7.2 years (range, 4 to 15). Mean Harris hip score improved 45 points preoperatively to 83 points postoperatively. Six hips (14.6%) required additional revision procedure : 3 for aseptic loosening, 2 for deep infection, and 1 for recurrent instability. Complications included 2 dislocations and 1 peroneal nerve palsy. Kaplan-Meier survivorship with an end point of reoperation for any reason was 88.5% (95% CI, 78.0% to 100%) at 7.2 years. For aseptic loosening of the acetabular component, the survival was 91.8% (95% CI, 80.8% to 100%) at 7.2 years. Rerevision with contemporary uncemented cup or antiprotrusio cage for failed revision THA acetabular components showed encouraging mid-term outcomes for this technically challenging condition. |
