Title: Effectiveness of Pain Relief Between Adductor Canal Block and Femoral Nerve Block in Total Knee Arthroplasty in General Anesthesia
Brief Summary: This study aims to compare the effectiveness of adductor canal block and femoral nerve block in total knee arthroplasty in general anesthesia. Two block techniques were proved safe and effective in pain control after total knee arthroplasty. But some authors insist that quadriceps muscle power was decreased by femoral nerve block. The study design is a double-blind randomized controlled trial. Fifty patients planed to undergo simultaneously bilateral total knee arthroplasty are randomised to receive ultrasound-guided femoral nerve block on one leg and adductor canal block on the other, in addition to combined general anaesthesia. The primary outcome was comparative postoperative pain in either extremity at four, eight, 12, 24, 72 hours and 7days postoperatively. Secondary comparative outcomes included motor strength by cybex test.
