Brief Summary

Anterior cruciate ligament repair (ACL) surgery presents moderate to severe pain during the inmediate postoperative period and the first days after surgery. In addition, due to the interest of surgeons and patients for early reinstatement, the use of blockages that decrease the strength of the quadriceps is avoided. Therefore, in recent years, the adductor canal block (ACB) has been used for postoperative analgesia with variable results. Genicular nerve block (GNB) has been used for pain management in patients with knee osteoarthritis and recently in knee arthroplasty surgery with results similar to the local anesthetic infiltration techniques by the surgeon (LIA). Considering their good results in these patients in addition to being a 100% sensitive block without risk of motor involvement. The investigators proposed this experimental study to evaluate tha analgesic efficacy of the genicular nerve block (GNB) compared with the adductor canal block (ACB) for the Anterior cruciate ligament (ACL) repair surgery.

Study Arms (2)

Adductor canal block

EXPERIMENTAL

Injection of local anaesthetics under ultrasound guidance in the adductor canal by the anaesthesiologist prior the surgery, after inducction of general anesthesia.

Procedure: Adductor canal block

Genicular nerve block

EXPERIMENTAL

Injection of local anaesthetics under ultrasound guidance in the genicular nerves ( Superomedial genicular nerve, superolateral genicular nerve and inferomedial genicular nerve) by the anaesthesiologist prior the surgery, after inducction of general anesthesia.

Procedure: Adductor canal block

Interventions

Adductor canal block PROCEDURE

Injection of the local anesthetic prior to the surgery, either in the the adductor canal or in the genicular nerves by the anesthesiologist under ultrasound guidance.

Also known as: Genicular nerve block

Adductor canal block; Genicular nerve block
