Background: Direct anterior hip replacement is a slightly aggressive surgical procedure but potentially widespread. It involves opening on the front of the hip to allow the joint to be substituted by moving muscles aside along their ordinary tissue planes without removing any tendons. Nevertheless, there is diminutive consent concerning the threats and profits of this method compared to the posterior approach (PA) regarding the rates of dislocation and infection. Methods: This research is a prospective study conducted in Erbil city from September 2015 to September 2017 on 57 patients, including 28 females and 29 males, with primary total hip arthroplasty (THA). Twenty-nine patients were enrolled in the direct anterior approach (DAA: First group), and 28 patients were registered in the PA group (PA: Second group). Their age ranged between 49 and 80 years, and the regular follow-up was 12 months for all patients. Results: It was found that using the DAA, there was a significantly (P ≤ 0.05) lower incidence rate of dislocation in patients undergoing THA than the PA. No significant difference in the rates of infection was noticed between both groups. However, slightly shorter operational time and extent of the incision were noticed in the DAA group, and less blood loss was found in the PA group (non-significant). Conclusion: We realized that DAA has a clear advantage over PA regarding the lower incidence in the dislocation risk and without variance in the infection rates.
