Core Tip
Core tip: In this retrospective analysis, intrathecal morphine (ITM) with spinal anesthesia and single shot femoral nerve block (FNB) with general anesthesia were compared in 54 patients undergoing primary total knee arthroplasty over two years at our institute. Pain scores and morphine consumption in 1st 24 h after surgery were significantly lower in ITM group compared to FNB group (P < 0.001); while complication rates, high dependency unit admission rates, and time to discharge from the hospital were similar in both groups. Also, patients in ITM group were highly satisfied (P < 0.001).
