PPV, positive predictive value; NPV, negative predictive value; ACL, anterior cruciate ligament; “specified”, by injury time, for both the ACL and the menisci.
Statistically significant findings were achieved for the anterior cruciate ligament and both menisci; patellofemoral data lacks in p-value, positive predictive value and sensitivity as all imaging diagnosis made were negative; specified lesions data for the anterior cruciate ligament and menisci lacks in sensitivity and specificity as it was evaluated as a whole.
