Adductor Canal Block for Knee Surgeries: An Emerging Analgesic Technique

In recent years, adductor canal block (ACB) has been introduced as an alternative for femoral nerve block with a great advantage of preserving or minimally reducing quadriceps strength. The technique is relatively easy and is performed under ultrasound guidance. Despite growing evidence regarding efficacy and safety of ACB following knee surgery, use of ACB is still limited to high volume ortho...

Adductor Canal Block for Knee Surgeries: An Emerging Analgesic Technique.

Adductor canal block versus femoral nerve block for total knee arthroplasty: a prospective, randomized, controlled trial.

BACKGROUND This prospective double-blinded, randomized controlled trial compared adductor canal block (ACB) with femoral nerve block (FNB) in patients undergoing total knee arthroplasty. The authors hypothesized that ACB, compared with FNB, would exhibit less quadriceps weakness and demonstrate noninferior pain score and opioid consumption at 6 to 8 h postanesthesia. METHODS Patients received...

Adductor canal block is useful but does not achieve a complete block of the knee.

W e congratulate Kwofie et al 1 on their thorough study on the motor effects after adductor canal block (ACB). The authors found no motor weakness after ACB in healthy volunteers using a relatively high volume of local anesthetic. The injection was made at a point considered distal to the motor supply to the quad-riceps femoris muscle. However, the motor branch to the vastus medialis muscle con...

Rehabilitation Outcomes for Total Knee Arthroplasties: Continuous Adductor Canal Block Versus Continuous Femoral Nerve Block

Objective To determine whether any strength, range of motion (ROM), or functional improvement exists in the adductor canal block (ACB) group after completion of inpatient rehabilitation and following the removal of the continuous block. Design Retrospective cohort. Setting Inpatient rehabilitation at discharge and outpatient orthopedic clinic for follow-up. Participants Two hundred forty-...
