Abstract
Polyethylene liner dissociation (PLD) is a rare but catastrophic complication following total hip arthroplasty (THA). When it occurs in the early postoperative period, it can be easy to miss the diagnosis. Liner dissociation has been reported previously with the Pinnacle® (DePuy), Harris-Galante® (Zimmer), and Trident® (Stryker) acetabular components. To the best of our knowledge, this is the first case reporting PLD in the G7® cup (Zimmer-Biomet). This case report, along with a review of the literature, highlights the clinical presentation, radiological imaging, treatment options, and technical tips to avoid PLD in the early postoperative period.
