Abstract
ObjectivesTo retrospectively review the mid-term outcomes of cementless femoral components used during revision arthroplasty. MethodsRecords of 52 hips with 28 women and 24 men (mean age 61.1 years) were reviewed in which cementless femoral revision was performed for aseptic loosening of the femoral component by a single senior surgeon. The clinical outcome was assessed using the Harris Hip Score. Radiological parameters followed were osseointegration, subsidence, remodelling and heterotropic ossification. ResultsMean follow-up period was 8.1 years. The mean Harris hip score improved from 32 to 81.8. Subsidence >10mm was noted in four hips within the first 6 months which was non-progressive. Osseointegration was noted in 42 hips; stable, fibrous integration was noted in the other 10 hips. Extended trochanteric osteotomy united in all cases (mean 5.2 months). ConclusionsBoth extensively porous-coated cylindrical stems and tapered, fluted long stems provide excellent outcomes and survival in reconstruction of femoral defects.
