As portrayed from a recent study published in ‘The Journal of Arthroplasty’, the revision primary direct anterior (DAA) total hip arthroplasty (THA) was found to be associated with an increase in odd ratio of superficial wound complications, but on the other hand, have a reduced dislocation rate.

Gregory Kurkis et al. in a study hypothesized that anterior approach revision surgery may have greater wound complications than the posterior hip revisions (PA) and also report on secondary outcome criterion.

All in all, 99 DAA and 191 PA revisions were considered. Descriptive stats- preoperative demographic features; indication for revision, operative characteristics; type of revision executed, components used, and postoperative complications were distinguished between the DAA and PA groups comprising multivariate analysis. The DAA cohort revealed an higher risk of superficial wound complications (7.1% versus 0.5%) and a lessened dislocation rate (2.0% versus 13.1%). A trend towards increased overall complications in the PA group (OR 1.71, p=0.078) followed, refer to the table below:
