Once the consultation has been completed, the physician will issue prescriptions for the usual medical treatment, laximetry prescription (GNRB) to be performed between 3 to 6 weeks after the accident when the knee is indolent and the prescription of the MRI to be performed between 7 days and 1 month after the accident. The physician will inform the patient that they should consult with the investigator's orthopedic surgeon once the results of GNRB and MRI are available within 6 weeks of the accident.
