RESUMO
A series of 120 primary total hip arthroplasties with minimal 10-year follow-up, in which a cementless, proximal-to-distal, dual-tapered geometry femoral component was used, was reviewed. At a mean follow-up interval of 12.20 years, a mean Harris hip score improvement of 38 points was calculated. Three (2.5%) femoral components were revised secondary to aseptic loosening, yielding a 97.5% survivorship. Thigh pain was mild or absent in 96.6% of the cases. Distal femoral osteolysis was observed in <2% of cases. The Harris hip score improvement, low incidence of severe thigh pain, high survivorship, and low incidences of significant stress shielding and distal osteolysis suggest excellent long-term results with the use of this uncemented tapered design, adding credence to the design rationale and justifying its continued use.
