The overall agreement across all MRI results between the two radiologists was good (kappa = 0.83, P < 0.001). MRI was found to have high sensitivity (90.7%) and moderate specificity (63.6%) in the diagnosis of injuries to the ACL; high sensitivity (90.4%) and moderate specificity (50%) in the diagnosis of injuries to the PCL; moderate sensitivity (79.1%) and low specificity (46.7%) in the diagnosis of injuries to the MCL; fair sensitivity (55.6%) and moderate specificity (68.4%) in the diagnosis of injuries to the LCL; fair sensitivity (61.5%) and low specificity (39.4%) in the diagnosis of injuries to the meniscus. The accuracy was good for ACL injuries (87.6%) and PCL injuries (84.5%), moderate for MCL injuries (69.1%) and LCL injuries (66.9%), low for the meniscus injuries (45.4%). The agreement between MRI results and intraoperative findings was moderate in the ACL injuries (kappa = 0.47) and PCL injuries (kappa = 0.39), poor in the MCL injuries (kappa = 0.26) and LCL injuries (kappa = 0.18), and meaningless in tears of the meniscus (Table (Table3).3). Only one of the 9 injured PLC was revealed by preoperative MRI, so the sensitivity and specificity cannot be calculated. The preoperative MR images of the injured ligaments
Just saw Dr Jesse Morse on twitter say an examination and MRI should already tell the folks treating him about a full tear or not. So they would already know by now he says.
