Summary
This is a single center, randomized, blinded trial in healthy volunteers. The volunteers will
receive bilateral placement of the new catheter corresponding to the adductor canal. Each
volunteer will have a catheter placed in the adductor canal in both legs. The catheters are
randomized to be placed either in the long-axis or short-axis plane of the adductor canal.
Both catheters will be injected with local analgesics (LA). Allocation will be blinded to the
volunteer and the investigator assessing sensory function. The volunteers will be sent home
with the catheter in situ and return the following day. Injection with LA is repeated and
sensory function is tested again. Furthermore catheter position is determined with ultrasound
during injection. If sensory function is not affected by injection of LA then the catheter is
visualized with ultrasound and repositioned followed by a second injection of LA and
subsequent assessment of sensory function
