Comparison of the Early Results of Lateral Direct Anterior Approach (L-DAA) and Traditional Posterolateral Approach (PLA) in Hip Arthroplasty

Objective. To evaluate the early results of lateral direct anterior approach (L-DAA) and traditional posterolateral approach (PLA) in hip arthroplasty. Methods. A total of 24 patients who underwent hip replacement from 2018 to 2021 were divided into PLA group (N=12) and L-DAA group (N=12) according to the method of random table number. Outcomes were evaluated between the two groups. Results. The length of incision was shorter; the amount of bleeding was less in the L-DAA group than that in the PLA group. The visual analogue scale (Vas) pain scores for the L-DAA group were significantly lower than that for the PLA group at 24 h, 72 h, and 1 month after operation, and Harris hip scores in the L-DAA group were significantly high in the PLA group at 1 month after operation. In addition, there are no statistically significant differences in acetabular anteversion, abduction, and angle between the two groups. Conclusion. L-DAA was superior to PLA for early recovery after hip arthroplasty.
