Measure
Single Shot Adductor Canal
Subjects had a catheter placed in the Post Anesthesia Care Unit following clinically indicated surgery with saline. Placebo: Saline filled catheter
Ropivacaine Continuous
Subjects had a catheter placed in the Post Anesthesia Care Unit following clinically indicated surgery with 0.2% ropivacaine dispersed in a continuous infusion. Ropivacaine Continuous Infusion: 0.2% continuous infusion 6mL/hr
Ropivacaine Intermittent Bolus
Subjects had a catheter placed in the Post Anesthesia Care Unit following clinically indicated surgery with 0.2% ropivacaine dispersed in pulsed intermittent bolus. Ropivacaine Intermittent Bolus: 0.2% intermittent bolus infusion 8mL every 2 hours
