Summary: | Introduction: Internal derangement of knee joint
constitutes a major source of morbidity. It includes a group
of disorders due to disruption of normal functioning of
ligaments and menisci of knee joint leading to persistent or
intermittent signs and symptoms such as pain, instability,
or abnormal mobility of the knee. Among these Anterior
Cruciate Ligament (ACL) tears are the most commonly
encountered injury in radiology practice.
Aim: To identify the various MRI imaging findings in
clinically suspected cases of ACL injury and to identify,
assess indirect signs of ACL tears.
Materials and Methods: This study was performed in the
Department of Radiodiagnosis, Mysore Medical College
and Research Institute, Mysuru, Karnataka, on patients
referred from Orthopedics Department for a period of one
year. Fifty patients with clinically suspected ACL tears
(37 men, 13 women) were included in this prospective
study. Patients were subsequently subjected to imaging of
knee using 1.5 T MRI 8 channel GE Brivo MRI machine.
Sequences used were axial, sagittal and coronal PD Fat
Sat; sagittal, axial and coronal T2 FSE and sagittal T1
FSE.
Results: Among 50 patients ACL was the commonest
ligament to be injured with complete tear being more
common than partial tear. Indirect signs of ACL injury were
evaluated and helped to corroborate the tears. Certain
patterns of associations of injuries were found such as ACL
tear with posterolateral corner injury and O’Donoghue’s
triad.
Conclusion: MR imaging of knee complements therapeutic
arthroscopies and would greatly reduce the need of
diagnostic arthroscopies. As MR is a non-invasive, painless
and morbidity-free modality for accurate preoperative
assessment, it is well accepted by patients. Hence, MR is
an excellent tool for evaluation of ACL pathologies. |
