Clinical Trends and Outcomes in Technology-Assisted Total Hip Arthroplasty.

In recent years, there has been a widespread focus on implementing technology in total hip arthroplasty (THA) to further improve precision and outcomes. This study aimed to identify recent trends in the utilization, clinical variables, and rate of adverse events for technology-assisted THA (TA-THA) and compare the outcomes to those of conventional THA. This retrospective cohort analysis of the ACS-NSQIP database queried data on THA patients (CPT 27130) from 2015 to 2020. Technology assistance was identified with CPT 20985, 0054T, and 0055T. Matched cohorts were created to compare clinical comorbidities and adverse events. This analysis included 219,216 conventional THAs and 2258 cases utilizing TA-THA. The number and percentage of surgeries utilizing technology, as well as the average operative time, consistently rose from 2015 to 2019, with all declining in 2020. Length of stay decreased yearly from 2015 to 2019, with an increase in 2020. There were no significant differences in the incidence of adverse events by year. Matched cohort analysis demonstrated that TA-THA led to longer operative times (102.6 ± 35.6 vs. 91.6 ± 37.4 min, < 0.001) and a shorter average length of stay (1.6 ± 1.4 vs. 2.0 ± 1.9 days, < 0.001). Transfusion rates were higher in the TA-THA cohort (6.0% vs. 4.4%, = 0.013). The usage of TA-THA increased from 2015 to 2019, with declines during 2020. TA-THA led to longer operative times, increased transfusion rates, and no difference in the incidence of adverse events compared to conventional arthroplasty. These findings demonstrate that TA-THA is growing in popularity without a significant improvement in short-term complication rates.
