Precoated femoral component with proximal and distal centralizers: results at 5 to 12 years.
One study, confounded by the use of crystalline polyethylene and ceramic heads, reported a high rate of early failure of a precoated femoral component with proximal and distal centralizers. The present study reports the prospective clinical and radiographic results, and 10-year survival data of 166 consecutive hybrid total hip arthroplasties using this femoral component. An A or B cement grade was obtained in 93% of hips. At a mean follow-up time of 7 years (range, 5-12 years), there were only 4 (2.4%) femoral failures. Ten-year survival of this component was 95% (confidence interval, 94%-99%). The rate of radiographic failure and revision of this component implanted with conventional polyethylene and cobalt chrome heads is similar to that reported with other "modern" femoral components.
