Direct anterior versus anterolateral approach in one-stage supine total hip arthroplasty. Focused on nerve injury: A prospective, randomized, controlled trial.
BACKGROUND The difference in clinical results between the direct anterior approach ( DAA ) and the anterolateral approach ( ALA ) for  total hip arthroplasty ( THA ) is still unclear . The purpose of this study was to compare clinical results , including nerve injuries , between DAA and ALA in one-stage bilateral THA in a prospect i ve , r and omized controlled trial . METHODS Thirty patients were recruited for primary bilateral THAs from 2014 to 2016 . The left and right hips of each patient were r and omly assigned to DAA and the others to ALA . We prospect ively compared the clinical results , incidence of lateral femoral cutaneous nerve ( LFCN ) injury , and tensor fascia lata ( TFL ) atrophy considered to be related to superior gluteal nerve injury between both approaches . RESULTS No significant difference was found in the clinical results between both sides at postoperative 1 year . Temporary symptom of LFCN injury was observed only in DAA sides ( 7/30 , 23.3 % ) . The ratio of 3-month postoperative to preoperative cross-sectional area of TFL on computed tomography was significantly lower on the side subjected to DAA ( DAA side , 78.8 ± 22.8 % ) than on the side subjected to ALA ( ALA side , 90.7 ± 17.7 % ) ( p < 0.01 ) . In magnetic resonance imaging at postoperative 1 year , the mean grade of fatty atrophy of TFL by Goutalier classification was significantly higher in DAA sides ( 2.00 ± 1.6 ) than in ALA sides ( 1.1 ± 1.3 ) ( p = 0.03 ) . CONCLUSIONS Excellent clinical results for both DAA and ALA were achieved . LFCN injury was found only in DAA sides . Although TFL atrophy was found in both approaches , it was found significantly more in DAA sides . Our study suggested that ALA should be used rather than DAA in terms of the risk of nerve injuries
