Use of Simplified Pain Questionnaire Among People Receiving Anterior Cruciate Ligament (ACL) Knee Surgery?

The goal of this randomized clinical trial is to compare opioid consumption among patients who receive a binary pain scale compared to those who receive a standard 10-point pain scale after undergoing anterior cruciate ligament (ACL) reconstruction surgery.
