Abstract: | We reviewed the clinical and radiographic results of a series of 215 consecutive hip arthroplasties in which a normalized, proportionalized, cemented femoral component was implanted. This component design may encourage more efficient force transmission from prosthesis to cement to bone and lessen hoop stresses and resultant interface failure. A total of 127 hips in 103 patients with a follow-up of 13 to 17 years (average, 14.8 years) were available for evaluation, which included survivorship analysis. An aseptic failure loosening rate of 3.9% at 15 years for this stem favorably compares with other reported series of first-generation and second-generation stems at similar follow-up. Excluding the 8 stems placed in varus, of which 3 required revision (failure rate, 37.5%), the series has a failure rate of 1.6%. |
