77 patients scheduled for ACL reconstruction were randomized to postoperative analgesia with either an adductor canal block or a femoral nerve block. The purpose of this study was to compare analgesic efficacy and functional recovery between groups. Patients administered the Please login to view the rest of this report.

Why was this study needed now?
Femoral nerve block is a common method for postoperative analgesia following anterior cruciate ligament reconstruction. However, the effect that femoral nerve block has on motor response has led to more recent studies investigating effective alternatives. The adductor canal block has been suggested as a possible alternative, though the majority of previous research has been conducted in populations undergoing total knee arthroplasty. Therefore, a trial comparing adductor canal block and femoral nerve blocks in ACL reconstruction was needed.
What was the principal research question?
In ACL reconstruction, how do the adductor canal block and femoral canal block compare regarding analgesic efficacy and functional recovery?
Population: 77 patients scheduled for ACL reconstruction.
Intervention: ACB group: Participants were administered a preoperative adductor canal block.
Comparison: FNB group: Participants were administered a preoperative femoral nerve block
Outcomes: Reported results included postoperative pain, time to the ability to perform straight leg raise, patient satisfaction, analgesic use, and time spent in the recovery room.
Methods: RCT; Single-blinded, Single-center
Time: Patients were followed for 1 week postoperatively.
