Acetabular Revision Arthroplasty Using an Uncemented Deep Profile Jumbo Component: A Ten to Sixteen Year Follow-Up Study.

BACKGROUND

The purpose of this study is to evaluate the outcome of revision total hip arthroplasty using an uncemented deep profile jumbo acetabular component in patients who had been followed for a minimum of 10 years postoperatively.

METHODS

Between 1997 and 2001, 61 revision total hip arthroplasties were performed in 58 patients, with use of the +5 Deep Profile acetabular shell. The outcome with regard to retention vs re-revision of the acetabular component was determined for every hip. At a mean of 13 years (range 10-16) postoperatively, 30 patients (32 hips) were living. The Harris hip score, radiographic results, complications, and Kaplan-Meier survivorship were evaluated.

RESULTS

In the entire cohort of 61 hips, 4 acetabular components have been re-revised. Two shells were re-revised for sepsis: 1 shell was re-revised for aseptic loosening and 1 for recurrent dislocation. In the 32 hips followed for a minimum of 10 years postoperatively, 2 cups have been re-revised: 1 for aseptic loosening and 1 for recurrent dislocation. One additional shell was loose by radiographic criteria. With failure defined as re-revision for any reason, implant survival (95% confidence interval) was 92.6% (81.0-97.2) at 16 years. With failure defined as re-revision for aseptic loosening, implant survival was 97.4% (82.8-99.6) at 16 years.

CONCLUSION

Revision total hip arthroplasty with the +5 Deep Profile acetabular component was associated with a good rate of survival at 16 years.
