Technology-assisted Total Hip Arthroplasty: A Contemporary Analysis of Regional Trends, National Trends, and 90-day Outcomes in a Nationwide Cohort.
Article in Arthroplasty today, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Technology-assisted total hip arthroplasty (THA)-including computer-navigated and robotic-assisted techniques-has emerged as a strategy to enhance component alignment and potentially improve postoperative outcomes. Although prior studies have described increasing utilization, contemporary trends and associated complication rates remain underexplored. Methods: A retrospective cohort study was conducted using a large national database to identify patients who underwent primary elective THA between 2010 and 2023. Patients were stratified into conventional vs technology-assisted THA groups, with the latter defined by the use of computer navigation or robotic assistance. Annual utilization trends were evaluated using linear regression, and 90-day postoperative complications were compared using multivariate logistic regression after adjusting for demographic, clinical, and regional factors. Results: Among 1,062,597 patients undergoing primary elective THA, 4% received technology-assisted procedures. Utilization increased from 1.2% in 2010 to 12% in 2023-a 927% relative increase. Regional variation was notable, with highest utilization in the Northeast and the lowest in the Midwest. Technology-assisted THA was associated with lower odds of 90-day complications (5.36% vs 6.26%; adjusted odds ratio [OR]: 0.77; 95% confidence interval [CI]: 0.75-0.80), particularly reduced odds of dislocation (OR: 0.64; 95% CI: 0.60-0.69) and periprosthetic joint infection, though with higher odds of wound dehiscence (OR: 1.15; 95% CI: 1.07-1.23). Conclusions: Utilization of technology-assisted THA has increased substantially across the United States, accompanied by improved short-term outcomes, most notably decreased dislocation. These findings support the potential clinical benefits of surgical technology in THA, while underscoring the need for ongoing evaluation of long-term results.
