An unpaired student’s t test was used to analyze the data between iPACK and LIA groups. Values are presented as mean ± SEM. iPACK: interspace between the popliteal artery and the capsule of the posterior knee, LIA: local infiltration analgesia, BPM: beats per minute SEM: standard error of the mean, PACU: Post-Anesthesia Care Unit, CI: confidence interval
