Abstract
This problem wasn’t solved despite trials to minimize it through changing either the concentration of drugs (10), or changing the position of catheter in relation to femoral nerve
(catheter in front or behind the nerve) (11).
Blocking the femoral nerve (or saphenous nerve) in the adductor canal is increasingly used for knee analgesia (12). It carries potential benefits that encourage anaesthesiologists to do
it. It has a motor sparing property (it blocks only the nerve to vastus medialis, which represent
only 8% of quadriceps power) (13).
Another potential value of adductor canal block that it allows blocking of other sensory
branches that are involved in knee innervations other than the saphenous nerve (14). ACB can
allow also a simultaneous blocking of sciatic nerve (anterior approach of sciatic nerve) (15) and
allows an easy catheter insertion within the adductor canal that can allow a continuous
postoperative analgesia (16).
