Brief Summary

The aim of this study is to compare the postoperative analgesic effect of femoral triangle block (FTB) and adductor canal block (ACB)after arthroscopic anterior cruciate ligament (ACL) reconstruction.

Conditions

Femoral Triangle Block; Adductor Canal Block; Anterior Cruciate Ligament Reconstruction

Outcome Measures

Primary Outcomes (1)

• Total morphine consumption

  Rescue analgesia of 3 mg morphine IV will be given if the Numeric Rating Scale (NRS) \> 3 to be repeated after 30 min if pain persists until the NRS \< 4. NRS will be assessed at 2, 4, 6, 12, and 24h postoperatively

  24 hours postoperatively

Secondary Outcomes (4)

• Time of 1st rescue analgesia

  24 hours postoperatively

• Pain score using Numeric Rating Scale (NRS)

  24 hours postoperatively

• Quadriceps strength

  24 hours postoperatively

• Patient satisfaction

  24 hours postoperatively

Study Arms (2)

Femoral Triangle Block (FTB) Group

EXPERIMENTAL

Patients will receive femoral triangle block (FTB) at the end of surgery.

Other: Femoral Triangle Block

Adductor Canal Block (ACB) Group

EXPERIMENTAL

Patients will receive adductor canal block (ACB) at the end of surgery.

Other: Adductor Canal Block

Interventions

Femoral Triangle Block OTHER

Patients will receive femoral triangle block (FTB) at the end of surgery. The probe will be positioned at the level where the medial border of the sartorius muscle intersects the medial border of the adductor longus muscle, a block needle advanced in an in-plane technique into femoral triangle. After negative aspiration, 2ml of saline will be injected to confirm the needle tip position close to the femoral artery then injection of 15ml of bupivacaine 0.25% will be performed.

Femoral Triangle Block (FTB) Group

Adductor Canal Block OTHER

Patients will receive adductor canal block (ACB) at the end of surgery. The probe will be positioned at the point midway between the anterior superior iliac spine and the upper pole of the patella. The adductor canal will be located as a hyperechoic structure beneath the Sartorius muscle and a block needle advanced in an in-plane technique toward the target nerve after negative aspiration, 2ml of saline will be injected into adductor canal to confirm the block needle tip within it, the block needle will be advanced with the guidance of ultrasound in an in-plane technique and 15ml bupivacaine 0.25% will be injected.
