Brief Summary

We hypothesize continuous adductor canal block with steroid adjuvant would offer no inferior analgesics and rehabilitation ability than continuous femoral nerve block for postoperative patients receiving total knee arthroplasty.

Study Arms (2)

adductor canal block

ACTIVE COMPARATOR

Continuous adductor canal block and single shot posterior tibial nerve block under ultrasound guidance and using nerve stimulating needle (bolus: 0.5% Ropivacaine 10-15ml with dexamethasone 4mg ;with single shot posterior tibial nerve block (8-10ml 0.5% ropivacaine)

Procedure: adductor canal block

continuous femoral nerve block

OTHER

Femoral nerve catheter inserted under ultrasound guidance using nerve stimulating needle administering ropivacaine bolus 10-15ml and infusing 0.2% ropivacaine at 4-6ml/h; plus a single shot posterior tibial nerve block under ultrasound guidance and use of nerve stimulating needle

Procedure: femoral nerve block

Interventions
