Abstract
The purpose of this prospective multicenter study was to evaluate results of 122 revision THAs using a 2nd generation modular femoral implant in 120 patients. Majority of cases had significant femoral bone loss. HHS improved from a pre-operative mean score of 46 to 88 points, and SF-36 scores improved from 31 to 44 points at 2- to 5-year follow-up. There were 18 cases of intraoperative fractures of which 10 were femur shaft, 7 trochanteric, and 1 acetabular. Dislocation incidence was 9% and overall survivorship at 5 years was 97%. Use of modular femoral implants provides versatility and simplification to restore stability, limb length and offset in patients undergoing femoral component revision, Additional steps need to be undertaken to minimize incidence of fracture and dislocation.
