Dearborn JT, Harris WH. Acetabular revision arthroplasty using socalled jumbo cementless components: an average 7-year follow-up study. J Arthroplasty.2000 ;15:8-15.[CrossRef][Medline]

Acetabular revision in the presence of major bone-stock deficiency is a difficult clinical and surgical problem. Of an original pool of twenty-four consecutive patients treated with an acetabular revision with a so-called jumbo (>65-mm) cementless hemispherical acetabular component, fifteen were followed for an average of seven years in our previous study. The current report presents the results for the twelve patients in this group who were alive at a minimum of twelve years (mean, 13.9 years) postoperatively and agreed to return for follow-up. The average final Harris hip score was 79 points. No acetabular shell had been revised because of aseptic loosening, and none was loose as seen radiographically. The complication rate was high but was largely related to infection. In the patients without infection, the fixation of these large sockets remained excellent at the time of long-term follow-up.

Level of Evidence: Therapeutic Level IV. See Instructions to Authors for a complete description of levels of evidence.
