[Short-term effectiveness analysis of one-stage bilateral total hip arthroplasty by direct anterior approach].

Objective: To compare the effectiveness of one-stage bilateral total hip arthroplasty by direct anterior approach (DAA) and by posterolateral approach, and to investigate the application value of DAA in one-stage bilateral total hip arthroplasty. Methods: The clinical data of 65 patients who underwent one-stage bilateral total hip arthroplasty by DAA or posterolateral approach between June 2010 and November 2015 were analyzed retrospectively. DAA was used in 34 cases (group A) and posterolateral approach was used in 31 cases (group B). There was no significant difference in the gender, age, body mass index, preoperative hemoglobin level, etiology, disease duration, preoperative Harris score, and preoperative visual analogue scale (VAS) score between 2 groups ( Results: The incision length, operation time, intraoperative blood loss, total blood transfusion volume, and hospitalization time of group A were significantly less than those of group B ( Conclusion: The application of DAA in one-stage bilateral total hip arthroplasty can significantly relieve the pain, accelerate the recovery of hip joint function, and improve the patient satisfaction. But in clinical application, more attentions should be paid to strictly grasp the indications and prevent the early complications. The long-term effectiveness needs to be further observed.
