Objective: To evaluate real-world outcomes of patients receiving ACTIS, a medial collared, triple-tapered (MCTT) hip system vs. other implants, for primary total hip arthroplasty (THA). Methods: Patients with THA between 2016–2021 from Mercy Healthcare Systems–Orthopedics Database were evaluated. The primary outcome was the 2-year revision. Secondary outcomes included operating room (OR) time, length of stay (LOS), and discharge disposition. Fine Stratification and Weighting (FSW) controlled for baseline characteristic differences between ACTIS and other implant groups. Cox proportional regression evaluated the hazard ratio (HR) for revision. Results: Among 9,225 patients with 10,205 THAs (mean [SD] age 66.8 [11.3] years, 56.0% female), MCTT was implanted in 1,591 hips and other implants in 8,614 hips. The balanced cohort included all 10,205 procedures (54.2% female; age 65.5 [11.3]; 14.1% Elixhauser index ≥5; 84.5% MCTT, 82.2% other since 2018; obesity 43.6% MCTT, 43.0% other). Two-year revision was 0.9% for MCTT and 1.8% for other implants (p =.021). HR for revision MCTT vs. other was 0.53 (95% CI 0.30–0.92; p =.023). Mean (SD) OR time was 69.07 (18.93) minutes for MCTT, 83.69 (43.88) for other implants (p
