Abstract
The aim of this paper was to assess the impact on stability of revision of 29 standard acetabular cups to press-fit uncemented dual mobility (DM) cups in THAs with recurrent dislocation. This series was composed of 17 women and 12 men aged on average 75.6 ± 8.1 years (55–88), operated on between November 2000 and July 2010. The average number of dislocations before revision surgery was 3.87 ± 1.79 (2–10), and the average time from primary procedure to revision was 6.6 ± 4.3 years (45–15 years). 9 patients (31.03 %) had already undergone one or more procedures for instability prior to revision to DM cup. All patients were reviewed at an average time of 46 ± 28 months (range: 17 months–11 years). Only one patient had redislocated in this time (3.4 %). This patient underwent a simple closed reduction and did not dislocate again.
Level of evidence: IV retrospective cohort study.
