About

This study aims to compare the effect of dual subsartorial block (DSB), adductor canal block (ACB), and femoral nerve block (FNB) for postoperative analgesia in patients undergoing total knee arthroplasty (TKA).

Full description

Total knee arthroplasty (TKA) offers increased joint mobility and painless ambulation to patients. Femoral nerve block (FNB) is commonly used to relieve postoperative pain and opioid consumption.

Adductor canal block (ACB) is a common analgesic intervention for postoperative pain control following TKA. The dual subsartorial block (DSB) is a novel procedure-specific and motor-sparing regional analgesia (RA) technique that may reduce overall postoperative opioid consumption when used in conjunction with multimodal analgesia.
