  • Title: Long-term survivorship of cemented all-polyethylene acetabular components in patients > 75 years of age.
    Author: Levy BA, Berry DJ, Pagnano MW.
    Journal: J Arthroplasty; 2000 Jun; 15(4):461-7. PubMed ID: 10884206.
    Abstract:
    Between 1974 and 1982, 132 consecutive hips in 112 patients >75 years of age were treated with primary total hip arthroplasty for osteoarthritis using a cemented all-polyethylene T28 socket and cemented T28 or TR28 stem with a 28-mm head size. At the time of review, 94 patients (110 hips [83%]) had died and 18 patients (22 hips [17%]) were still living (mean age at follow-up, 93 years). Five hips (5 patients) were lost to follow-up. Clinical follow-up averaged 8.9 years for the entire group and 14.6 years for patients still living. Only 2 acetabular components have been revised (1 for recurrent dislocation, 1 for infection). No acetabular component has required revision for aseptic loosening. Survivorship free of acetabular revision for aseptic loosening at 10 years was 100%; free of symptomatic acetabular loosening, 97.4% (95% confidence interval, 91.8-100%); and free of acetabular loosening, 95.9% (95% confidence interval, 89.7-100%). The commonest complication was postoperative hip dislocation, which occurred in 11 hips (8.7%) and which required reoperation in 2 hips. Cemented acetabular components implanted in patients >75 years of age with a diagnosis of osteoarthritis showed a high rate of survivorship free of revision and free of symptomatic aseptic loosening.
