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

摘要

Background: 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 remains controversial. We therefore performed a meta-analysis to compare the effects of ACB+PI with PI alone on pain controll after TKA.
