Combined adductor canal block with periarticular infiltration versus periarticular infiltration for analgesia after total knee arthroplasty

AbstractBackground:Both adductor canal block (ACB) and periarticular infiltration (PI) have been shown to reduce pain after total knee arthroplasty (TKA) without the motor blockade. However, the efficacy and safety of combined ACB with PI (ACB + PI) as compared to PI alone for analgesia after TKA re
