Objectives
Narrative objectives1
We test the hypothesis that providing different local ansthetics (0.15% ropivacaine 4ml/h vs. 0.1% levobupivacaine 4mL/h) produces comparable quadriceps muscle power reducutions and analgesic efficacy when uses in continuous femoral nerve blocks after total knee arthroplasty.

Assessment
Primary outcomes
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 percentage of the preoperative MVIC.
Key secondary outcomes
Secondary endpoints included postoperative knee range-of-motion, ambulatory ability, pain scores(Visual Analog Scale) at rest and during knee movement, and the consumption of additional analgesics.
