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 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...

Comparison of Adductor Canal Block and Femoral Nerve Block for Postoperative Pain in Total Knee Arthroplasty

A total knee arthroplasty (TKA) has always been associated with moderate-to-severe pain. A systematic review of randomized controlled trials (RCTs) and non-RCTs was performed to evaluate the efficacy and safety of pain control of adductor canal block (ACB) and femoral nerve block (FNB) after TKA.Relevant literatures about the ACB and FNB after TKA for reducing pain were searched from Medline (1...

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...
