Abstract: Purpose: Purpose: The study investigated the benefits of the direct anterior approach (DAA) compared to the posterolateral approach (PLA) in patients over 75 years of age.Materials and Methods: Materials and Methods: This study included 144 patients who underwent total hip arthroplasty (THA) from December 2012 to November 2021.Group A had 93 patients with a mean age of 80.8±5.0 years, who underwent DAA.Group B had 51 patients with a mean age of 79.7±4.6 years, who underwent PLA.Clinical outcomes included operative time, time to ambulation, walking ability, and complications.Results: Results: There were no demographic differences between the groups.The mean age was 80.9±5.0 years in Group A and 80.5±4.8 years in Group B. Mean operative time was 94.2±7.2 minutes in Group A and 91.2±8.8 minutes in Group B (P=0.02).Early ambulation within 3 days postoperatively was seen in 72 patients (77.4%) in Group A and 31 patients (60.8%) in Group B (P=0.03).No significant change was seen in modified Koval Index in Group A (4.35 to 4.06, P=0.51), while Group B showed a significant decrease (4.47 to 3.88, P=0.04).The postoperative modified Koval index negatively correlated with time to ambulation (P=-0.17,P=0.04).Dislocation occurred in 3 patients (3.2%) in Group A and 7 patients (13.7%) in Group B (P=0.02).No differences were found in medical complications or mortality.Conclusion: Conclusion: THA via DAA may provide earlier functional recovery than PLA, with comparable safety in patients over 75 years of age.
