Brief summary

The purpose of this study is to assess early ambulation following total knee replacement in patients receiving continuous adductor canal block with posterior capsular injection compared to continuous femoral nerve block with tibial nerve block.

Interventions

PROCEDURECanal Block and Capsular Injection

Continuous Adductor canal block with 15ml of ropivacaine 0.2% with epinephrine 1:400,000 followed by an infusion of ropivacaine 0.2% at 6ml per hour for 2 days post operatively. This is combined with ultrasound guided posterior capsular knee injection with 30ml ropivacaine 0.2% with epinephrine 1:400,000.

PROCEDUREFemoral Nerve Block with Tibial Nerve Block

Continuous femoral nerve block with 15ml of ropivacaine 0.2% followed by an infusion of ropivacaine 0.2% at 6ml per hour for 2 days after surgery combined with tibial nerve block in the popliteal fossa with ropivacaine 0.5% up to 15ml.
