Study 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.

Study Description

Aim of the study is to compare the efficacy of the adductor canal block to the combined adductor canal block and saphenous nerve block at the distal third of thigh in the intermuscular plane between Vastus Medialis and Sartorius muscles in pain relief following knee arthroscopic anterior cruciate ligament repair.

After written informed consent, patients will be randomized in three groups:

Group (Adductor 20): Ultrasound guided adductor canal block will be performed with injection of 20 ml bupivcaine 0.5%.

Group (Adductor 30) Ultrasound guided adductor canal block will be performed with injection of 30 ml bupivacaine 0.5%. Group (Adductor/saphenous ): Ultrasound guided adductor canal block will be performed by injection of 20 ml bupivacaine 0.5%, combined with ultrasound guided saphenous
