Background: Excellent intermediate-term results with use of tapered femoral components in primary total hip arthroplasty have been reported. The purpose of this study was to update our previous report and to evaluate the outcome of total hip arthroplasty with use of the porous Taperloc femoral component in patients who had been followed for a minimum of eighteen years postoperatively. Methods: One hundred and forty-five consecutive uncemented total hip arthroplasties in 138 patients were performed between 1983 and 1985, by a single surgeon, with use of the Taperloc femoral component. The outcome of every femoral component with regard to stem fixation, retention, or revision was determined for all 145 total hip replacements. At a mean of twenty years (range, eighteen to 22.6 years) postoperatively, fifty-eight patients (sixty-five hips) were living. In fifty living patients (fifty-seven hips), the femoral component had not undergone revision surgery. Evaluation of the living patients included clinical and radiographic analysis and recording of complications. Results: Of the eighty patients (eighty hips) who had died, five hips had undergone revision of the femoral component. Only one stem had been revised for aseptic loosening, and no femoral component had been definitely loose by radio- graphic criteria. In the remaining sixty-five hips in the fifty-eight living patients, eight femoral components were revised. No femoral component underwent revision for aseptic loosening. Definite radiographic evidence of femoral component loosening occurred in one hip. In the fifty living patients (fifty-seven hips) who had not undergone femoral component revision, there was a significant improvement in the mean Harris hip score from 49.3 points preoperatively to 85.4 points at the time of latest follow-up (p = 0.001). Survivorship analysis of all 145 hips, with revision for any reason as the end point, estimated that the survival rate for the femoral component was 87% (95% confidence interval, 79% to 93%) at twenty-two years. Conclusions: Primary total hip arthroplasty with the Taperloc femoral component is associated with a low rate of aseptic loosening at a mean follow-up of twenty years. Level of Evidence: Therapeutic Level IV. See Instructions to Authors for a complete description of levels of evidence.

    Objective: Trochanteric non-union may alter the biomechanics and the forces going through the hip joint leading to increased polyethylene wear and hence a higher revision rate. The aim of our study was to determine if trochanteric non-union was associated with a higher incidence of acetabular...

    Background and purpose: The Zweymüller-Plus system (SL-Plus stem, Bicon-Plus threaded cup) for primary total hip arthroplasty (THA) was introduced in 1993, as a successor of the Alloclassic THA with a few modifications in the conical stem shape and a new biconical threaded cup with a...

    Background: Evidence suggests some metal-on-metal (MOM) THAs have higher rates of failure and subsequent revision than other bearing surfaces. However, there are few studies demonstrating how these patients fare after revision. Questions/purposes: We asked: (1) What is the short-term...

    Background: This study was undertaken to provide a basis for decision-making when a well-fixed cemented cup is encountered at the time of a revision of a femoral component of a total hip replacement. It may be beneficial to retain the cup in some instances and thus reduce morbidity,...

    Subsidence of femoral hip prostheses with a rough surface has been associated with osteolysis and loosening. However, recent evidence has suggested that smooth-finish tapered stems may not incur these problems. An experimental monobloc satin finish, tapered femoral component was designed to...
