| Popis: | Limiting the risk of dislocation is one of the main aims of both dual mobility and Lefevre retentive cups. However, these devices have never been compared. The goal of our study was to compare these devices in total hip arthroplasty revisions for instability. The judgement criterion was non-recurrence of dislocation in a follow-up period of eight years. This retrospective case-control study compared two continuous paired series of total hip arthroplasty revisions for instability. These series included 63 patients and 159 patients with implantation of a Lefevre retentive cup and a dual mobility cup, respectively. The success rate at eight years (i.e., no recurrence) was 91 ± 0.05% and 95 ± 0.02% in the Lefevre retentive cup and dual mobility groups, respectively. The difference was not statistically significant (p = 0.6). It seems that the Lefevre retentive cup provides comparable outcomes with the dual mobility cup in the total hip arthroplasty revisions for instability, avoiding recurrence in long term. |
