Patient 11 (Table 1) is a 67-year-old woman who had a failed Zimmer Trilogy® Longevity® Constrained liner placed for recurrent instability, as seen on the AP radiograph (A). She was revised to a Trident® Osteonics constrained liner (B), which subsequently failed as well (C). She then underwent acetabular revision with implantation of DM components (D). She has a stable hip without subsequent dislocations at 5 years postoperatively.
