editorial: 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 orthopedic centers where trained anesthesiologists in regional anesthesia are available. in this editorial, we aim to briefly review current evidence about acb.
