ACL-deficient patients with combined injury of ligaments other than the medial collateral ligament or knee fracture were excluded. Patients aged 16 to 55 who were diagnosed with ACL rupture on magnetic resonance imaging and Kellgren-Lawrence grade &lt; II on radiograph were included. All ACL injury patients were divided into 2 groups based on physical examination under anesthesia: 58 patients with a positive anterior drawer and Slocum test under anesthesia served as the AMRI group; 25 patients with a positive anterior drawer test but negative Slocum test under anesthesia served as the isolated ACL injury group (nonanteromedial rotatory instability [NAMRI] group). Preoperative magnetic resonance imaging was used to characterize bone morphological factors, including lateral femoral condyle ratio, medial femoral condyle width (MFCW), notch width, notch width index, coronal tibial slope, medial tibial depth, medial tibial posterior slope, and lateral tibial posterior slope. Medial structural injuries (superficial medial collateral ligament, deep medial collateral ligament [dMCL], and anteromedial retinaculum [AMR]) were assessed via ultrasound and magnetic resonance imaging. All patients did not experience postoperative infections or other surgical complications during at least 3 months of follow-up.

Preoperatively, patients completed questionnaires including demographics, medical history, Visual Analog Scale (VAS), Brief Resilience Scale, Six-Item State-Trait Anxiety Inventory, Patient Health Questionnaire-2, Single Assessment Numeric Evaluation score, and patient-reported outcome measures (PROMs) including Patient-Reported Outcomes Measurement Information System physical component. Postoperatively, patients received acetaminophen, meloxicam, tramadol, gabapentin, and oxycodone. Morphine milligram equivalents (MMEs) and VAS were assessed at multiple timepoints through 6 months. PROMs were completed at 3 and 6 months. Patients were analyzed as a single group and partitioned by Brief Resilience Scale and Six-Item State-Trait Anxiety Inventory scores into low-normal (1.00-4.30) and high (4.31-5.00) resilience, and low (20-37) and moderate-high (38-80) anxiety groups, respectively.</p><p><strong>Results: </strong>Prior opioid use positively predicted VAS and MME at 48 to 72 hours and MME at 6 weeks.

Patients with prior opioid use exhibited greater postoperative pain and narcotic consumption.
