ABSTRACT
The purpose of this study was to assess the survivorship of a proximally coated, cementless femoral stem used for total hip arthroplasty at a minimum 5-year follow-up by assessing clinical outcomes and implant survival. A total of 936 primary total hip arthroplasties were performed in 854 patients by 3 high-volume surgeons between 2001 and 2007. Patients included 385 men and 469 women with a mean age of 56 years (range, 20-88 years) and a mean follow-up of 7 years (range, 5-11 years). The aseptic revision rate related to the femoral component was 0.3%. Three patients underwent revision of the femoral component. Mean postoperative Harris Hip Score improved to 91 points (range, 70-100 points). When stratified by primary cause of total hip arthroplasty, no differences were found in implant survivorship or postoperative Harris Hip Scores. With the exception of the 3 patients who underwent revision surgery, postoperative radiographic evaluation of the stems demonstrated no progressive radiolucencies, component malalignment, change in component position, or implant subsidence at most recent follow-up. These results are encouraging and indicate a 0.3% revision rate for the femoral component. The cause of primary total hip arthroplasty did not affect the clinical outcomes. These types of prostheses will provide patients with a stable implant that is expected to have excellent durability and longevity.

Relatively little data are available on the impact of the patient's preoperative status and socioeconomic factors on the clinical results following THA. Questions/purposes:...

    Background: Uncemented stems have been used in THA for well over two decades, but there are relatively few studies reporting on the results after 20 years. Questions/purposes: The purpose of this study was to evaluate at a minimum followup of 20 years (1) hip scores; (2) radiographic findings,...

    Purpose: A tapered straight cementless stem was used for revision in a group of old and very old patients. We wanted to know whether the use of this implant could achieve satisfactory results despite age and osteoporosis. Methods: We retrospectively analysed data of 77 elderly patients (77 hips)...
