 There has been dispute about the location at which the adductor canal block should be performed 3-6. Point A has been disputed to be within the femoral triangle and would therefore be a femoral nerve block as suggested by a small body of evidence 4-5. Clinically, it is unclear if there is a difference between quadriceps muscle weakness between the two approaches although it could be hypothesized placing a block at point A would lead to more quadriceps muscle weakness. With information gathered from this study, we plan to perform a clinical study by performing the nerve blocks at these two points with different volumes of local anesthetic and compare the amount analgesia and motor weakness between the two different approaches.
