PRIMARY TOTAL HIP ARTHROPLASTY WITH A CEMENTLESS TAPERED FEMORAL COMPONENT: TWO-SIX-YEAR RESULTS

Abstract

This prospective study reports the midterm outcome of total hip arthroplasty performed in a consecutive series of patients using a tapered uncemented femoral component. From Nov. 2001 to Apr. 2006, total hip arthroplasties were performed in 138 patients (150hips). The clinical records and the routine serial radiographs of these patients were monitored closely over a 1-year period. Clinical evaluation was done by Harris hip score before surgery and at last follow-up. Radiological evaluation was done on plain radiographs. The average follow up period was 4.05 years. There was a significant improvement in functional outcome of these patients as measured by Harris hip score. There were no revisions for aseptic loosening of the femoral component in this series, accounting for an overall survivorship of 100%. The study confirms that the midterm outcome of this stem is excellent, with no revisions.
