Bone deficiencies in dysplastic acetabula create technical difficulties during total hip arthroplasty (THA). Bulk femoral head autograft (FHA) is one method to increase cup coverage and bone stock of the true acetabulum; however, only limited data exist on its efficacy through a direct anterior approach (DAA). This study aimed evaluate outcomes FHA THA via DAA hips.Retrospective review 34 patients (41 hips) with dysplasia (Crowe I-III) who underwent primary at single institution was performed. Surgical procedures were performed traction table intraoperative fluoroscopy highly porous-coated placement acetabulum. Patients assessed clinically radiographically minimum 2 years postoperatively (range, 7).The average modified Harris Hip Score improved from 31.9 ± 10.8 94.1 5.8, Merle d'Aubigné 7.5 2.8 16.6 1.1, visual analog pain score 7.9 2.7 1.4 (all P < .001). All hips had an "anatomic" inferomedial position postoperatively, horizontal 43.4%. Mean postoperative limb-length discrepancy 21.8 16.1 mm 1.6 5.7 (P There no cases revision THA, nor complications such as dislocation, infection, or osteolysis.Reconstructing can be successfully accomplished increased acetabular accurate correction discrepancy.
