Abstract
Purpose
The adoption of robotic-assisted total hip arthroplasty (THA) is increasingly widespread, yet its influence on outcomes in outpatient surgery remains uncertain. This study aimed to evaluate whether robotic assistance reduces the rate of 90-day postoperative events in patients undergoing outpatient THA, compared to those in inpatient procedures.
Methods
This historical-prospective cohort study analyzed 706 primary THA cases performed between January 2017 and January 2023 by three senior surgeons. Patients were grouped into outpatient (n = 132) and inpatient (n = 576) cohorts. From December 2019, robotic-assisted THA using the MAKO™ system was implemented. Propensity score matching was used to minimize baseline differences between groups. The primary outcome was the occurrence of any event within 90 days post-surgery, including readmissions, reoperations, and other complications. Secondary outcomes included functional scores, length of hospital stay, and intraoperative factors such as blood loss and Operative Room (OR) time.
Results
No significant differences were found between inpatient and outpatient groups in terms of gender, age, BMI, ASA score, or surgeon. The 90-day event rates were similar between the two groups (8.59% vs. 9.38%, p > 0.999). However, outpatient THA was associated with lower blood loss (p = 0.02) and shorter hospital stays (p < 0.001). Multivariate analysis identified prolonged OR time (> 2 h), BMI ≥ 25, and manual surgical techniques as significant risk factors for 90-day events. Robotic-assisted surgery, although not statistically significant (p = 0.105), showed a trend towards reducing complications in outpatient THA.
Conclusion
Outpatient THA is a safe alternative to inpatient surgery, with no significant difference in 90-day postoperative events. Robotic-assisted surgery appears to reduce complications, particularly in the outpatient setting, and may optimize outpatient care pathways. Further research is needed to confirm these findings and explore long-term outcomes.
