Background

Wound complication after primary direct anterior (DAA) hip arthroplasty has been reported in the literature but there has been no comparison regarding revision anterior vs revision posterior (PA) hip arthroplasty. The authors hypothesize that anterior approach revision surgery may have increased wound complications compared with posterior hip revisions and also report on secondary outcome metrics.

Methods

Ninety-nine DAA and 191 PA revisions were included for analysis. Preoperative demographic characteristics, indication for revision, operative details, type of revision performed, components utilized, and postoperative complications were compared between DAA and PA groups including multivariate analysis.

Results

The DAA cohort demonstrated an increased risk of superficial wound complications (7.1% vs 0.5%, P = .003) and a decreased dislocation rate (2.0% vs 13.1%, P = .002). There was a trend toward increased overall complications in the PA group (OR 1.71, P = .078).

Conclusion

Revision DAA THA is associated with an increased risk of superficial wound complications, but may impart a decreased dislocation rate.
