Summary
This is a randomized noninferiority interventional study to determine the equivalence of two
adductor canal block (ACB) methods: mid-thigh and distal thigh in patients undergoing medial
foot, medial ankle, or medial leg surgery. Sixty eight patients will be identified during
their orthopedic presurgical clinic visit, anesthesia preoperative clinic visit or Day
Surgery Unit (Zale Lipshy Hospital, Clements University Hospital, and University of Texas
Southwestern Outpatient Surgery Center) for eligibility. Eligible individuals may be
introduced to the study in the orthopedic presurgical clinic or the anesthesia preoperative
clinic by staff. After consent patients will be randomized (break-seal method) to receive
either a mid-thigh or distal thigh block using ropivacaine prior to foot, ankle, or leg
surgery. The following measurements will be obtained to determine the change in sensory
distribution: pinprick test with Neuropen, maximum voluntary isometric contraction before and
after block, postoperative pain scores (24 hrs and at discharge) and postoperative opiate
consumption.
