Adductor Canal Block (ACB) Versus ACB /Saphenous Block in Patients Undergoing Anterior Cruciate Ligament Repair

Summary

Knee surgeries are associated with severe postoperative pain. Blocking the femoral nerve (or saphenous nerve) in the adductor canal is increasingly used for knee analgesia. It carries potential benefits that encourage anesthesiologists to do it. It has a motor sparing property. Injection of local anesthetics in this lengthy canal that contains a variable amount of connective or fibrous tissue might lead to a patchy distribution of local anesthetics. Thus, the possibility of incomplete block of the saphenous nerve (most important nerve in knee innervations) cannot be excluded.
