Hybrid revision total hip arthroplasty - A 7-year follow-up study

The hybrid method for fixation of total hip arthroplasty (THA) has shown excellent results during the first decade in primary operations. To investigate its role in revision surgery, data on 48 revision THAs in 45 patients that met the inclusion criteria were gathered prospectively, using HGP cementless acetabular components and precoated cemented femoral components inserted with so-called second generation femoral cementing technique in each case. For the 48 hips during an average follow-up period of 7.4 years, no acetabular components was loose or had pelvic lysis. One acetabular component was revised for recurrent dislocation; I of 48 femoral components was revised for aseptic loosening and I for periprosthetic fracture. Three additional femoral stems (6%) were loose. In this small series, the hybrid concept for revision of failed nonseptic THAs has shown excellent results.
