  • Title: Cementless hemispheric acetabular component for acetabular revision arthroplasty: a 5- to 19-year follow-up study.
    Author: Lian YY, Yoo MC, Pei FX, Kim KI, Chun SW, Cheng JQ.
    Journal: J Arthroplasty; 2008 Apr; 23(3):376-82. PubMed ID: 18358376.
    Abstract:
    This study evaluated the 5- to 19-year clinical and radiographic results of cementless acetabular revision. Between 1986 and 1998, 130 hips (125 patients) underwent cementless acetabular revisions. Ten patients were lost to follow-up; 6 patients died. One hundred nine patients (114 hips) were reviewed at a mean follow-up of 8.8 years. The mean Harris hip score improved from 62.1 to 90.7 at final follow-up. Two hips underwent repeat revision. Twenty-two hips developed cavitary osteolysis. Kaplan-Meier survivorship at 121 months was 98.2% with repeat revision for any reason as the end point and 89.5% with repeat revision or radiographic loosening as the end point. Cementless acetabular revision provides favorable clinical and radiographic results, and the initial disease and age may adversely affect the outcomes.
