Intraoperative anesthetic typically consists of either general anesthesia (GA) or isolated regional anesthesia (RA).


A retrospective propensity-matched cohort analysis on patients undergoing TSA was performed to determine differences between GA and RA in regard to patient population, complications, LOS and hospital readmission.


4158 patients underwent TSA with GA or isolated RA. Propensity-matching resulted in 912 patients in each cohort. RA had lower overall in-hospital complications and greater homebound discharge disposition with lower 90-day readmission rates than GA.


After TSA, isolated RA was associated with lower in-hospital complications, readmission rates and odds of hospital readmission than GA.
