  • Title: Matched-pair analysis of cemented and cementless acetabular reconstruction in primary total hip arthroplasty.
    Author: Clohisy JC, Harris WH.
    Journal: J Arthroplasty; 2001 Sep; 16(6):697-705. PubMed ID: 11547367.
    Abstract:
    In a matched-pair study of primary total hip arthroplasty, 45 all-polyethylene cemented acetabular components were compared with 45 cementless, hemispheric, titanium acetabular components. At 9 to 12 years, 1 of the cemented acetabular components was revised for aseptic loosening, and 14 (31%) were radiographically loose. Nine (20%) cemented acetabular components had pelvic osteolysis. In the cementless acetabular component group, 2 well-fixed components were revised. No components were radiographically loose, and 3 (7%) had pelvic osteolysis. Thirty-eight (97%) of the patients in each group were satisfied with the surgery. The clinical results of the cemented and cementless components were excellent. The cementless components had less loosening (P <.001) than the cemented components.
