  • Hylamer vs Conventional Polyethylene in Primary Total Hip Arthroplasty: A Long-Term Case-Control Study of Wear Rates and Osteolysis JOURNAL OF ARTHROPLASTY Huddleston, J. I., Harris, A. H., Atienza, C. A., Woolson, S. T. 2010; 25 (2): 203-207


    The long-term results of Hylamer implants have not been reported previously. Clinical and radiographic results of a consecutive series of 43 patients (45 hips) who had primary total hip arthroplasty using Hylamer liners were compared with those of 37 patients (43 hips) who had conventional liners after 10-year follow-up. The linear wear rates for Hylamer and conventional polyethylene acetabular liners were 0.21 and 0.20 mm/y, respectively. The number of pelvic osteolytic lesions and their size detected on plain radiographs were significantly greater for Hylamer liners. Seven Hylamer hips were revised or are pending revision for osteolysis (16%) compared with 1 control hip. Close radiographic surveillance of patients who have Hylamer liners and evidence of osteolysis found on plain radiographs is warranted.
