Sponsor's own description

There has been dispute about the location at which the adductor canal block should be performed (3-6). Two Common approaches have been used for ultrasound guided adductor canal blocks with the 'point of entry' being:

1. Point A: midway point between the ASIS and base of patella
2. Point B: Point which is 2-3 cm proximal to the site where the femoral artery becomes the popliteal artery as it traverses away from the sartorius muscle towards the femur at the adductor hiatus (2)

We want to determine ultrasound anatomy in healthy volunteers by:

1. Measuring the distance between Point A and Point B
2. Studying the ultrasound anatomy at Point A and B - Determine their location with respect to the adductor canal and femoral triangle.

This will allow us to determine which is the best site for performing an adductor canal block
