INTRODUCTION: The increased use of the direct anterior approach (DAA) for primary total hip arthroplasty (THA) has extended to revision THA. This systematic review evaluated studies reporting both the utility and clinical outcomes of revision THA using DAA, focusing on studies comparing revision approaches. MATERIALS AND METHODS: A review of the Cochrane Library, EMBASE, and MEDLINE databases identified 577 publications. 538 were excluded after abstract screening. Full-text review identified 21 studies with 1627 patients. All studies were retrospective, level IV evidence. MINORS criteria rated 14 as poor and seven as moderate. Five studies compared DAA to alternative approaches. Meta-analysis was not performed due to significant heterogeneity and lack of comparative studies. RESULTS: The most common indications for revision were aseptic loosening (n = 929) and polyethylene wear (n = 158). The majority of the studies (n = 11/21) performed primarily acetabular revision or head-liner exchanges. Half the revisions (50.6%; n = 823/1627) included femoral revisions (35.2%; n = 573/1627) or combined femoral-acetabular revisions (15.4%; n = 250/1627). However, 80.6% (n = 462/573) of femoral revisions were from two non-comparative studies. Among the five comparative studies, two included femoral or combined revisions with significantly more performed using the posterior approach. Three of the five comparative studies did not find the DAA protective against postoperative dislocation. The overall complication rate was 14.0%; periprosthetic femoral fracture (n = 106), dislocation (n = 80), and infection (n = 36) were most common. Fourteen studies reported patient-reported outcome measures, demonstrating consistent improvements following revision THA. CONCLUSIONS: Current data on revision DAA THA are limited due to their retrospective nature. They demonstrate the ability to safely perform acetabular and head-liner revisions in carefully selected patients. Comparative studies lack femoral revisions, show a propensity for femoral fractures, and exhibit selection bias. Higher-quality, comparative prospective studies are needed.
