Single-institution retrospective cohort study of 295 revision THAs comparing dual mobility cups (DMC, n=184) to standard mobility cups (SMC, n=111) performed over a decade, asking whether DMC reduces dislocation risk without increasing aseptic loosening — including in patients under 55 years old.
When planning revision THA — especially for instability or in patients with multiple prior surgeries — dual mobility cups offer a significant reduction in postoperative dislocation without the early loosening penalty historically feared, making them a strong default choice over standard cups in the revision setting, including in patients under 55 years.
