Secondary Outcome Measures:
  • satisfaction with anesthesia [ Time Frame: 1 month ] [ Designated as safety issue: No ]
  • pain control [ Time Frame: 24-72hrs, 2weeks, 4weeks ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: Single Shot Sciatic Nerve Block
Single shot sciatic nerve blocks will be performed by resident trainees supervised by faculty.
 Drug: Bupivacaine
Bupivacaine 0.625% with epinephrine 1:300,000
Active Comparator: Continuous Sciatic Nerve Block
Continuous sciatic nerve block catheters will be performed using an insulated needle connected to the negative lead of a constant current nerve stimulator. The catheter will be advanced under ultrasound guidance. A test dose of 1.5% lidocaine with epinephrine will be injected to confirm catheter placement. All subjects will receive a portable pump. The subjects will follow standard protocol discharge instructions in regards to removing the catheter themselves.
 Drug: Ropivacaine
0.2% ropivacaine 5 ml/hr with a 5 ml bolus/hr.
