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.

Conditions

Osteoarthritis, Knee

Outcome Measures

Primary Outcomes (1)

• AVERAGE PAIN

  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).

  08:00AM to 24:00 on the first day following surgery

Secondary Outcomes (7)

• Procedure duration

  Prior to surgery

• Opioid consumption

  Postoperative days zero and one

• Distance Ambulated

  Physical Therapy sessions on postoperative day one

• Worst pain score (NRS 0-10 reported by patient)

  Postoperative day , entire day

• Number of vascular pictures during placement

  During the catheter placement procedure
