title: Uncemented jumbo cups for revision total hip arthroplasty: a concise follow-up, at a mean of twenty years, of a previous report.
abstract: Uncemented jumbo cups are commonly used for acetabular revision because they are technically straightforward to implant and provide good intermediate-term results. Understanding long-term survival is particularly important because this method is common and because jumbo cups do not provide notable bone stock restoration. The purpose of the present study was to determine the twenty-year results of jumbo cup use during revision total hip arthroplasty. In the original publication, we reported on eighty-nine patients who underwent revision with an uncemented jumbo cup with a single design (Harris-Galante) prior to 1993. The Harris Hip Score (HHS), radiographic results, and Kaplan-Meier survivorship curves were evaluated. Mean follow-up was twenty years. The mean postoperative HHS was 71 compared with 56 preoperatively (p=0.001). A total of five jumbo cups were revised for aseptic loosening; one, for infection; and one, for recurrent dislocation. Eight liners were revised with retention of the metal acetabular component: six during femoral component revision, one for wear, and one for recurrent dislocations. Twenty-year survivorship was 88% free from aseptic loosening of the metal acetabular component, 85% free from aseptic loosening or radiographic evidence of definite loosening of the metal acetabular component, and 83% free from revision of the metal acetabular component for any reason. The twenty-year results of revision with uncemented jumbo acetabular components demonstrated acceptable clinical outcomes and radiographic stability. These results justify the use of jumbo cups as a common method of acetabular revision.
