Compare the Quadriceps Function of Adductor Canal Block Versus Femoral Nerve Block With Electromyography Following Total Knee Arthroplasty

Adductor canal block and femoral nerve block are the most commonly used nerve blocks for pain control after total knee arthroplasty. The block area for adductor canal is a sensory branch near the knee area, which can potentially reduce the effect of motor blockage of quadriceps muscle. We try to proof adductor canal block can reduce the pain level after surgery effectively and preserve the muscle power of quadriceps muscle. Therefore, the rehabilitation course can be reduced and further lowering the risks of falling and complications.
