Objective  To compare the early rehabilitation effects of total hip arthroplasty (THA) with direct anterior approach (DAA) versus posterior approach (PA). Methods  A retrospective analysis was made in the data of 83 patients with unilateral osteonecrosis of the femoral head between March 2014 and May 2017. Forty-eight patients were treated with THA via PA (PA group) and 35 patients were treated with THA via DAA (DAA group). There was no significant difference in gender, age, body mass index, stage of osteonecrosis of the femoral head, and disease duration between 2 groups (P>0.05). The length of incision, operation time, total amount of bleeding, the time of first postoperative walking with crutch, the time of first postoperative walking without crutch, the Harris scores, and the visual analogue scale (VAS) scores of 2 group were recorded and compared. Results  All incisions healed primarily and no infection, dislocation, or fracture occurred. All patients were followed up 30.2 months on average (range, 6-44 months). The numbness symptom caused by the lateral femoral cutaneous nerve injury occurred in 2 patients of DAA group and released after symptomatic treatment. The length of incision, total amount of bleeding, the time of first postoperative walking with crutch, and the time of first postoperative walking without crutch of DAA group were significantly superior to those of PA group (P<0.05). The Harris scores of DAA group were significantly higher than those of PA group at 2 weeks and 1 month after operation (P<0.05), while no significant difference was found between 2 groups before operation and at 3 months and 6 months after operation (P>0.05). The VAS scores of DAA group were significantly lower than those of PA group at 1 day, 4 days, 1 week, and 2 weeks after operation (P<0.05), while no significant difference was found between 2 groups before operation (P>0.05). Conclusion  DAA is meaningful to enhanced recovery after THA. But it should be chosen carefully because of the disadvantages, such as long learning curve, limited indications, and requirements of specific instruments.
