title: Squeaking in a Delta ceramic-on-ceramic uncemented total hip arthroplasty.
abstract: Squeaking is one of the main concerns related to the use of ceramic-on-ceramic total hip arthroplasty. Although it has received much recent publicity, most of the previous reports on this complication have been related to the use of the second generation of alumina ceramics combined with a cup having an elevated metal rim to protect the ceramic liner from neck impingement. We report a patient with a third-generation Biolox Delta (CeramTec AG, Plochingen, Germany) ceramic-on-ceramic uncemented total hip arthroplasty without an elevated metal rim in the cup who presented with a squeaking hip at 23 months postoperative. Although this complication was mainly related to a specific design in the literature, this case demonstrates that newer generation of ceramics can also present squeaking.
