Study Arms:
- Single Shot Sciatic Nerve Block (Type: ACTIVE_COMPARATOR): Single shot sciatic nerve blocks will be performed by resident trainees supervised by faculty. Bupivacaine 0.625% with epinephrine 1:300,000 will be injected incrementally in 3-ml aliquots to a total volume of 0.4 ml/kg (minimum, 20 ml; maximum, 35 ml).
- Continuous Sciatic Nerve Block (Type: ACTIVE_COMPARATOR): 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 that will infuse 0.2% ropivacaine 5 ml/hr with a 5 ml bolus/hr. The subjects will follow standard protocol discharge instructions in regards to removing the catheter themselves.

Based on this trial design, predict the completion outcome and termination type (if applicable).
