To evaluate 90-day revision rates, early complications, functional recovery, and operative characteristics associated with a modern collared triple-tapered cementless femoral stem in an outpatient surgical setting.
Retrospective cohort study of 525 consecutive primary direct anterior total hip arthroplasties performed by 15 fellowship-trained surgeons across ambulatory surgery centers between September 2024 and August 2025.
Evaluated 90-day all-cause and stem revisions using Kaplan–Meier estimates, early complications, patient-reported outcome measures (HOOS-JR, FJS, VR-12) at 12 weeks, and operative time comparing automated versus manual impaction.
The 90-day Kaplan–Meier revision-free estimate was 99.62% for all-cause revision and 99.81% for stem revision, with 2 revisions (0.4%), a 0.2% periprosthetic fracture rate, and a 1.0% dislocation rate.
Patient-reported outcome measures improved significantly at 12 weeks, with HOOS-JR increasing by 28.7 points and Forgotten Joint Score by 41.9 points (both p < 0.0001), achieving minimal clinically important differences in 84.2% and 85.8% of patients, respectively.
In a within-surgeon analysis of 384 automated and 58 manual impaction cases, automated impaction device use was not associated with operative time (adjusted difference: 0.18 min; 95% CI: −2.04 to 2.39; p = 0.8764).
