Association between anesthetic approach and clinical outcomes of ACL reconstruction: a retrospective cohort study

In the short-term, GA had increased revision ACLr (RR 2.00, p = 0.01), postoperative pain (RR 1.56, p < 0.01), and opioid dependence (RR 1.96, p < 0.01), but less knee stiffness (RR 0.49, p < 0.01) and physical therapy (PT) (RR 0.87, p < 0.01) than combined anesthesia. RA had higher postoperative pain (RR 1.44, p = 0.02) and opioid prescriptions (RR 1.16, p < 0.01), but less PT (RR 0.62, p < 0.01) than combined anesthesia. GA had less knee stiffness (RR 0.43, p < 0.01) and opioid prescriptions (RR 0.80, p < 0.01), but more PT (RR 1.38, p < 0.01) than RA.
