All the tests were performed with univariable logistic regression and adjusted for preoperative KOOS QoL using logistic regression.
ACL, anterior cruciate ligament; BMI, body mass index; KOOS, Knee injury and Osteoarthritis Outcome Score; PASS, Patient Acceptable Symptom State; PLC, posterolateral corner; QoL, Quality of Life; ROC, receiver operating characteristic.
