Summary

This is a randomized clinical trial in healthy volunteers. 12 volunteers will have suture-method catheters placed in the adductor canal of each leg using the long-axis plane and short-axis plane technique. The investigators will inject LA in both catheters to confirm correct position. Following return of cold sensation the catheter is then displaced intentionally. The orifice is identified by injection of isotonic saline to ensure a proper displacement (spread outside of the adductor canal) and the distance from the delivery orifice of the catheter to the adductor canal is noted. A second investigator will assess distance from the LA delivery orifice of the catheter to the adductor canal using hydrodissection with isotonic saline to pinpoint the delivery orifice and subsequently reposition the catheter to obtain LA spread within the adductor canal. Successful repositioning is defined as a combination of LA spread within the adductor canal and loss of cold sensation on the medial part of the lower leg.
