In recent years, adductor canal block (ACB) has been introduced as an alternative for femoral nerve block with a great advantage of preserving or minimally reducing quadriceps strength. The technique is relatively easy and is performed under ultrasound guidance. Despite growing evidence regarding efficacy and safety of ACB following knee surgery, use of ACB is still limited to high volume ortho...

Wake Forest School of Medicine 73 Background: For ultrasound-guided saphenous nerve blockade within the adductor canal, the location of the saphenous nerve relative to the superficial femoral artery may be important for continuous blockade or low-volume, diagnostic block. Currently, there are inconsistencies in the literature and anatomy textbooks as to the anatomic relationship of these two st...

BACKGROUND Femoral continuous peripheral nerve blocks (CPNBs) provide effective analgesia after TKA but have been associated with quadriceps weakness and delayed ambulation. A promising alternative is adductor canal CPNB that delivers a primarily sensory blockade; however, the differential effects of these two techniques on functional outcomes after TKA are not well established. QUESTIONS/PUR...

BACKGROUND AND OBJECTIVES Adductor canal block (ACB) has been suggested as an analgesic alternative to femoral nerve block (FNB) for procedures on the knee, but its effect on quadriceps motor function is unclear. We performed a randomized, blinded study to compare quadriceps strength following adductor canal versus FNB in volunteers. Our hypothesis was that quadriceps strength would be preserve...
