Summary

This study employs a randomized controlled trial to investigate whether bupivacaine liposome injection for adductor canal block can effectively improve lower limb muscle strength after total knee arthroplasty.

Conditions

  • TKA
  • Muscle Strength

Interventions

PROCEDURE

a single-injection adductor canal block

An ultrasound-guided adductor canal block is performed via the conventional adductor canal approach. Under ultrasound guidance, 20 milliliters of 1.33% bupivacaine liposome is injected into the adductor canal.

PROCEDURE

continuous femoral nerve block

An ultrasound-guided perineural sheath block of the femoral nerve is performed via the conventional femoral nerve approach. A femoral nerve catheter is then placed and connected to an analgesia pump containing 150 milliliters of 0.20% ropivacaine.
