No Difference in Functional, Radiographic, and Survivorship Outcomes Between Direct Anterior or Posterior Approach THA: 5-Year Results of a Randomized Trial.

Background: Both the direct anterior approach (DAA) and posterior approach (PA) to THA have known advantages and disadvantages. The comparison between DAA and PA THA has been widely explored during the early postoperative period. However, few randomized trials have compared these approaches at a minimum follow-up of 5 years; doing so would be important to establish any differences in mid-term outcomes or complications.

A Prospective Randomized Clinical Trial in Total Hip Arthroplasty-Comparing Early Results Between the Direct Anterior Approach and the Posterior Approach.

Background: We report a prospective randomized study comparing early clinical results between the direct anterior approach (DAA) and posterior approach (PA) in primary hip arthroplasty.

Methods: Surgeries were performed by 2 senior hip arthroplasty surgeons. Seventy-two patients with complete data were assessed preoperatively 2, 6, and 12 weeks postoperatively.
