We test the hypothesis that providing different infusion techniques (continuous infusion of 6mL/h or patient-controlled infusion 3mL/bolus per 30min of 0.08% levobupivacaine) produces comparable quadriceps muscle power reductions, analgesic efficacy and rehabilitation progress when uses in the femoral nerve block after total knee arthroplasty.
Efficacy
Confirmatory
Explanatory
Phase III
The primary endpoint is the difference in maximum voluntary isometric contraction (MVIC) of the quadriceps 48 hours after surgery compared with the preoperative MVIC, expressed as a real amount of reduction and a percentage of the preoperative MVIC.
Secondary endpoints included postoperative knee range-of-motion, ambulatory ability, Knee Society Score, pain scores(Visual Analog Scale) at rest and during knee movement, and the consumption of additional analgesics.

Treatment
Device,equipment |
Postoperative continuous femoral infusion of levobupivacaine 0.08% 6mL/h for 24 hours.
After 24 hours of continuous infusion, switch to patient-contorolled bolus infusion of levobupivacaine 0.08% 3mL/bolus for additional 24 hours.
Postoperative continuous femoral infusion of levobupivacaine 0.08% 6mL/h for 48 hours, using dummy PCA botton.
