Analgesic efficacy and quadriceps strength of adductor canal block versus femoral nerve block following total knee arthroplasty

摘要

Femoral nerve blocks (FNBs) provide effective analgesia after total knee arthroplasty, but have been associated with quadriceps weakness. Adductor canal block (ACB) is a promising alternative option that delivers a primarily sensory blockade. The aim of this study was to determine whether ACB provides superior quadriceps strength and similar pain control than FNB.
