Actual (reported)Quadriceps femoris muscle strength
The primary end point will be the quadriceps femoris maximum voluntary isometric contraction (MVIC) expressed as a percentage of the pre-ropivacaine MVIC: post / pre x 100; with the two sides of each subject compared with each other
percentage of baseline muscle strength six hours after infusion initiation
Each subject will have one lower extremity (Right or Left) randomized to receive a perinural catheter, placed anterior to the femoral nerve, with a continuous infusion of local anesthetic and then the outcomes will be measured.
Each subject will have the opposite lower extremity (Right or Left) randomized to receive a perinural catheter, placed posterior to the femoral nerve, with a continuous infusion of local anesthetic and then the outcomes will be measured.
Extremity randomized to Anterior Placement will be given a peripheral nerve block with the catheter placed just anterior to the femoral nerve. 4cc of Ropivicaine will be administered continuously every hour by a pain pain pump and the outcome measures will be tested.
Extremity randomized to Posterior Placement will be given a peripheral nerve block with the catheter placed just posterior to the femoral nerve. 4cc of Ropivicaine will be administered continuously every hour by a pain pain pump and the outcome measures will be tested.
