Brief Summary:
Adductor canal (AC) nerve block is a commonly used modality for postoperative pain control after total knee arthroplasty (TKA). When the adductor canal is viewed by ultrasound, the femoral artery and femoral vein can easily be identified, however, the nerve that is to be blocked is often not visible. For this reason, the femoral artery is used as a landmark for the block. There currently are no studies examining the optimal placement of the nerve block catheter relative to the femoral artery in the canal. The goal of this study will be to examine the relationship between nerve catheter tip location relative to femoral artery within the adductor canal for continuous AC nerve blocks. The investigators specifically will compare postoperative pain as well as incidence of vascular puncture during the procedure and time to complete the procedure for two different catheter locations.

Arm Intervention/treatment
Experimental: Above Artery Group Procedure: Above Artery Catheter Placement
Nerve catheter placed between superficial femoral artery and sartorial muscle

Active Comparator: Between Artery and Vein Group Procedure: Between Artery and Vein Placement
Nerve catheter placed between superficial femoral artery and femoral vein




Primary Outcome Measures :
  1. AVERAGE PAIN [ Time Frame: 08:00AM to 24:00 on the first day following surgery ]
    Average pain on post operative day 1 following surgery as measured on a numeric rating scale (0-10, 0=no pain, 10=worst imaginable pain).


Secondary Outcome Measures :
  1. Procedure duration [ Time Frame: Prior to surgery ]
  2. Opioid consumption [ Time Frame: Postoperative days zero and one ]
  3. Distance Ambulated [ Time Frame: Physical Therapy sessions on postoperative day one ]
  4. Worst pain score (NRS 0-10 reported by patient) [ Time Frame: Postoperative day , entire day ]
  5. Number of vascular pictures during placement [ Time Frame: During the catheter placement procedure ]
  6. Intravascular injection assessed by heart rate response to epinephrine in injection [ Time Frame: During the catheter placement procedure ]
  7. Total local anesthetic infused on first postoperative day [ Time Frame: Postoperative days zero and one ]
