Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Catheter Anterior to Femoral Nerve
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.
Catheter Anterior to the Femoral Nerve
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.
Catheter Posterior to Femoral Nerve
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.
Catheter Posterior to the Femoral Nerve
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.
