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.

Pain Scores
The primary endpoint will measure subjective pain scores using a Visual Analog Scale ranging from 0 (no pain) to 100 (severe intolerable pain) at 12-hour intervals during the first 72 hours of the postoperative window. A higher score means worse outcome.
Time frame: 0-72 hours post op
Total Postoperative Opioid Consumption (Total MME)
The secondary endpoints will measure perioperative opioid consumption through postoperative day 2 in 12-hour intervals and converted into morphine milligram equivalents using standard conversions.
Time frame: up to 72 hours post-op
Range of Motion (Degrees)
An additional secondary endpoint is the range of motion, measured in degrees, of the operative knee at post-op visit 1 and 2. The post-op measurements will be compared to the pre-operative measurements. The scale of range of motion is from 0 - 135 degrees. The higher the score (degrees), the better the outcome.
Time frame: up to two months after surgery
