This study will consist of patients 12 years and older undergoing ACL reconstruction using a quadriceps or bone-patella tendon bone (BTB) graft. The patients will be randomized to adductor canal block alone, or adductor canal block + iPACK block. The primary goal will be to determine the differences in postoperative pain during the first 72 hours when comparing the two groups. Secondary outcomes will include opioid utilization during the first 72 hours postoperatively and range of motion including terminal knee extension at postoperative follow-up visits.

This study will compare the safety and effectiveness of a new facemask, the Tao mask, as compared to the standard mask for manual ventilation of patients with BMIs of 40 or greater who are undergoing elective surgery. The Tao mask and the standard mask will both be used for each patient but the order of evaluating the masks will be randomized.
