Functional outcomes after nonrecurrent dislocation of primary total hip arthroplasty.
The influence of dislocation on functional outcomes of primary total hip arthroplasty is unclear. The purpose of this study was to assess the effect of nonrecurrent dislocations treated with closed reduction after primary total hip arthroplasty on postoperative outcome in the short to medium term. Ninety-six patients were enrolled in this retrospective case-control study. There were 32 patients who had a postoperative dislocation. The control group consisted of 64 matched patients who did not dislocate. All patients had a minimum of 1-year follow-up. The 2 groups were compared using the SF-12, reduced WOMAC, and satisfaction questionnaire. There was no statistical difference between the 2 groups in subjective functional outcomes using the WOMAC or SF-12. However, there was a trend toward better quality of life scores in the control group, and they were more satisfied with their surgery compared with the dislocation group.
