View clinical trials related to Adductor Canal Block.
Filter by:The adductor canal block (ACB) is the standard of care for analgesia after Anterior Cruciate Ligament (ACL) repair. ACB is performed by injecting local anesthetic (freezing) in the subsartorial canal in the thigh which is about 7-10cm long. Preliminary evidence suggests that different injection sites within the canal may produce different degrees of analgesia and quadriceps motor block. This trial seeks to determine the effects of various ACB injection sites on postoperative analgesia and motor power following ACL repair.
The blockade of the femoral nerve (FNB) is the most common postoperative pain therapy after total knee replacement. Because of motor-driven weakness of the quadriceps muscle induced by femoral nerve block mobilization of Patients is difficult even dangerous (falls) and hospital stays are extended. An alternative method could be an adductor canal block (ACB). Anatomical studies of the adductor canal demonstrated that the adductor canal contains the saphenous nerve, a pure sensory nerve for medial and anterior aspects of the knee and the tibia without any motor function. This prospective, double-blinded, randomized study investigates the effect of FNB and ACB on quadriceps motor weakness and analgesia determined by Numeric Rating Scale (NRS). We expect the ACB to be superior in muscle strength but equal in pain score. Both groups receive an additional anterior sciatic nerve block for complete sensory block of the operated knee
