This prospective study reports the midterm outcome of total hip arthroplasty performed in a consecutive series of patients using a tapered uncemented femoral component. The cohort consists of 631 patients (700 hips). The clinical records and the routine serial radiographs of these patients were monitored closely over a 5-year period. Follow-up averaged 4.35 years. There was a significant improvement in functional outcome of these patients as measured by Harris hip score and short-form 36.There were 4 revisions for aseptic loosening of the femoral component in this series, accounting for an overall survivorship of 99.4%. The study confirms that the midterm outcome of this stem is excellent, with a low revision rate.
