Introduction: In recent years, the advent of new procedures, surgical instruments, and surgeon skills has contributed to a reduction in the number of early complications that can arise after hip arthroplasty. Among the most frequent are femoral loosening, deep vein thrombosis, and dislocation. Objective: To evaluate the rate of intraoperative complications and complications within the first 12 months after a hip arthroplasty performed utilizing the direct anterolateral approach; and to compare the results to a series published in 2007. Materials and Methods: Retrospective cohort study, which included patients who underwent surgery for primary hip osteoarthritis at two institutions, divided into: group I (468 patients who were operated between June 1999 and June 2003) and group II (344 patients who were operated between January 2018 and January 2020). Results: The global rate of complications in group II was 4.7%. Deep vein thrombosis was the most frequent event, and there were no episodes of dislocation. The use of 22 mm diameter heads was associated with a higher risk of dislocation compared to surgeries in which larger heads were used (OR= 6.7 - 95% CI 1.2 - 78.2). Conclusions: Total hip replacement through a direct transgluteal anterolateral approach had a low global rate of complications within the first postoperative year. Complications were reduced by almost half in surgeries performed between 2018 and 2020, compared to the previous series, mainly in regards to dislocation.
