Effectiveness of Pain Relief Between Adductor Canal Block and Femoral Nerve Block in Total Knee Arthroplasty
Effectiveness of Pain Relief Between Adductor Canal Block and Femoral Nerve Block in Total Knee Arthroplasty
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.
Total knee arthroplasty(TKA) is very popular in nowadays. But almost patients complained of
 postoperative pain and it affect the delay of early mobilization which prevent knee
 stiffness, lessens hospital stay and improves overall patient satisfaction and outcome of
 TKA. Intravenous patient-controlled analgesia (PCA) or epidural analgesia is a conventional
 postoperative analgesia. Recently other block techniques like a adductor canal block and
 femoral nerve block were known for good methods of pain relief after TKA. However, femoral
 nerve block reduces quadriceps muscle strength thereby potentially compromising postoperative
 mobilization. Therefore, it is necessary to evaluate the effectiveness of pain treatment and
 the preservation of muscle function after the procedure of adductor canal block and femoral
 nerve block.

 The present study aimed to determine and compare the efficacy of adductor canal block and
 femoral nerve block combined with general anesthesia on (1) postoperative pain control, (2)
 early patient ambulation and functional recovery and (3) change of muscle power after total
 knee arthroplasty.
