The Influence of Age and Sex on Early Clinical Results After Hip Resurfacing : An Independent Center Analysis

Patient selection is critical to the excellent medium-term clinical results after hip resurfacing. We assessed the influence of age and sex on early survivorship and functional outcome by comparing 100 female hips resurfaced with male hips resurfaced for the same period. In patients older than 55 years, Harris hip score improved to 97.4 in males compared with 91.2 (P < .01) in females with a revision rate of 2.2% and 7.4%, respectively. There was no correlation between age and functional score. Three percent of females and 1.3% of males sustained a femoral neck fracture. Hip resurfacing provides excellent early functional recovery in males and females. However, the revision rate in older females is high. Changes to surgical technique may minimize the risk of early failure in this group.
